.SHORT TERM ...
(Today through Friday night)
Issued at 255 AM CDT Thu May 2 2024

A cold front was pushing southward and was just about to move into
the Oklahoma Panhandle early this morning. This front will likely
push through the southern Texas Panhandle by mid morning.
Thunderstorms will be possible along and ahead of the front this
morning, mainly across the eastern Panhandles. A few thunderstorms
may be possible across the far southeast Texas Panhandle late
tonight as upslope flow combines with low level warm air
advection.

On Friday, winds return to the south and southeast.  This will
advect moist air back into the region behind the cold front. Showers
and thunderstorms will be possible through the day given the low
level moisture and warm air advection.

Friday night, a cold front moves through and this could spark
additional showers and thunderstorms.  Some of these storms could be
severe with large hail and damaging winds the main threats.  An
upper level short wave trough moving across the Panhandles will also
aide in the lift department.

.LONG TERM ...
(Saturday through Wednesday)
Issued at 255 AM CDT Thu May 2 2024

Showers and thunderstorms are expected to continue through Saturday
in the post frontal environment.  Plus and additional short wave
trough is expected to move across.  Showers and thunderstorm chances
continue Saturday night into Sunday as yet another short wave trough
moves across.

The upper level flow then increases from the southwest Sunday night
into Monday as a strong upper level closed low moves from the
northern Rockies onto the northern high Plains. This low will have a
negatively tilted trough extending southward from it that will swing
across the Panhandles Monday morning.  Southwest winds will respond
to the upper level short wave and dry air will sweep across the
Panhandles on Monday leaving the region POP free, except for the far
southeast Texas Panhandle where some moist air may hang on long
enough for some thunderstorms to develop during the afternoon.

The forecast then remains dry for Tuesday and Wednesday as a fast
zonal flow aloft spreads across the Panhandles.

High temperatures are expected to be around to just below average
for today through Sunday.  Temperatures will then rebound to above
normal again for Monday through Wednesday.

.AVIATION...
(06Z TAFS)
Issued at 1148 PM CDT Wed May 1 2024

A cold front will push south across the TAF sites this morning.
North winds in the 20 to 25 knot range with higher gusts will be
expected. Winds will slowly decrease by late this afternoon to 10
to 15 knots and they will turn more northeast and east.

MVFR cigs are expected at AMA before the front and right after the
front. MVFR cigs may be possible at GUY behind the front, but
confidence is not high enough to add those cigs in a this point.

Office: EWX FXUS64 KEWX 020823 AAA AFDEWX Area Forecast Discussion...UPDATED National Weather Service Austin/San Antonio TX 323 AM CDT Thu May 2 2024 ...New SHORT TERM, LONG TERM... .SHORT TERM... (Today through Friday) Issued at 235 AM CDT Thu May 2 2024 The complex of strong to severe thunderstorms that affected the northern Hill Country last night into the overnight hours is rapidly moving away into the HGX and FWD CWAs. Also the potential of heavy rains is coming to an end as well. However, we will continue with the Flood Watch for a few more hours to allow flooded waters to recede. For the rest of today's forecast: Isolated to scattered showers and isolated thunderstorms are forecast for South Central Texas throughout the day. The Rio Grande and southern Edwards Plateau areas have better probabilities to stay dry for the morning hours while locations along and east of Highway 281 have better chances to experience shower and thunderstorm activity as an upper level short wave over central Texas pushes to northeast. There is plenty instability in place across the local area and this helps for a quick shower or thunderstorm to develop with the heating of the day. Any shower or thunderstorm that manages to develop has the potential to become strong to marginally severe with large hail and damaging winds being the main threats. Also, precipitable water values are around 1.2 to 1.7 inches, which means that any strong updraft could produce a heavy downpour in a short period of time. Cloudy skies are expected to prevail for most of the day with the exception of the Rio Grande, where partly cloudy skies are forecast for the mid to late afternoon. Today's highs are forecast to range from the mid 80s across the Hill Country, I-35 corridor and Coastal Plains to low and mid 90s along the Rio Grande. Later tonight, things are expected to stay relatively quiet for the most part with some isolated showers or a few thunderstorms along and east of Highway 77. Isolated to widely scattered showers and thunderstorms are expected across the local area as the dry-line sits across west Texas and a weak frontal boundary slowly pushes into central Texas. Friday's highs range from the mid 80s along and east of Interstate 10 and Interstate 35 to upper 80s through mid 90s across the southern Edwards Plateau and Rio Grande Plains. && .LONG TERM... (Friday night through Wednesday) Issued at 235 AM CDT Thu May 2 2024 HREF members seem to suggest a stormy afternoon Friday to carry over into the evening for Friday night. The GFS is also a bit more bullish on convection for Friday night. For this reason have pushed some areas of the CWA into a chance category for storms, as the WPC QPF for 00-06Z suggests a robust round of storms rolling off the higher terrain into the Rio Grande Plains. Repeated rounds of isolated to scattered convection will keep the stormy narrative lively, but as has been experienced for much of the spring the better potential has favored the Hill Country and Central Texas. while there has been little predictability with the most recent activity, and likely to remain the case in the short-term, there is perhaps a period from noon to midnight Saturday, where more organized storm clusters can generate a cool outflow boundary and potentially spread farther south for a better coverage across the area. Aside from that the San Antonio area and areas south of I-10 and east of I-37 look to end up on the short end again in the need for drought-relieving rains. Rain chances de-escalate Sunday, and by late Sunday night the forecast pivots toward a more hot and dry scenario for the work week. while a weak SW flow pattern aloft will remain over TX, stronger dynamics over the Central Plains will likely keep a strong inversion over much of TX with some hot/dry plateau air spilling NE from Mexico. Thus a dry-line is expected to invade into South Central TX while the moist sector to the east is expected to be too shallow to give us a shot at convection. Monday should be a transition day to the hot weather but some areas may remain fairly mild and humid from the recent rains. Then the heat ramps up Tuesday and continues through at least Wednesday. Some triple digit heat is projected for the Rio Grande Plains by Tuesday, and the central and eastern counties could get into the mid-upper 90s by Wednesday. Any lingering humidity could combine with this heat for a low-end Heat Advisory potential. && .AVIATION... (06Z TAFS) Issued at 1224 AM CDT Thu May 2 2024 A complex of strong to severe thunderstorms are moving across the Hill Country while pushing to the northeast. Some activity at the tail end of this feature could clip KAUS within the next hour or two. Therefore, included a TEMPO group with -TSRA for KAUS. In addition, low cigs at IFR category are forecast overnight into the middle of the morning for KAUS. Similar situation apply for KSAT and KSSF where IFR cigs are expected to prevail overnight through at least 18Z Thursday. MVFR cigs return sometime in the mid to late afternoon. KDRT sits at MVFR but around dawn lowering to IFR. MVFR cigs return late morning with cigs lifting to VFR by 17Z. Southeasterly flow 5 to 10 knots are forecast to prevail through the forecast period. && .PRELIMINARY POINT TEMPS/POPS...

(Tonight through Thursday night) Issued at 147 PM CDT Wed May 1 2024 The short-term forecast period will continue to feature a steady state pattern, that being warm, humid and rain-free with continued onshore flow. Morning and nighttime hours will continue to see overcast skies while afternoon hours will see some breaks in the overcast. Daytime highs will be slightly warmer than normal while nighttime lows will be warmer than normal. For tonight and Thursday night, overnight lows are progged to be in the mid to upper 70s (some +4-8F degrees above average). The high temperature on Thursday is expected to be in the upper 80s to mid 90s (some +2-3F degrees above average) across Deep South Texas and the Rio Grande Valley. && .LONG TERM... (Friday through next Wednesday) Issued at 147 PM CDT Wed May 1 2024 Shortwave energy, upslope flow and strong to extreme instability will produce isolated to scattered convection initially across the Sierra Madre in the late afternoon and evening on both Fri and Sat. Most of this convection is expected to wane significantly before reaching the Rio Grande Plains or Upper Valley given the increasing cap strength and lack of forcing across our CWA. For now, will maintain slight chance POPs for just Zapata county for these Fri and Sat time periods. Otherwise, strong capping within the 915-630 mb layer will keep our convective chances close to nil through most of, if not all, of the extended forecast period. The main weather story will be the building heat next week. A broad strengthening mid/upper ridge axis will continue to expand its grip and influence on our CWA next week. The result will be increasing subsidence, even drier conditions, and rising temps. Diminishing cloud cover will further add to the building heat. H8 temps by Wed will be 25-28 degrees Celsius! Widespread daytime highs in the 90s through the weekend will gradually be replaced with 100s during the Mon-Wed timeframe across inland areas, especially west of I-69C. An expanding Major HeatRisk area by Tue and Wed will prevail across areas west of I-69C. As for Heat Indices, we could be looking at marginal heat advisories for this same geographical area by Wed. && .AVIATION... (06Z TAFS) Issued at 1237 AM CDT Thu May 2 2024 MVFR to VFR will continue to be the rule at the aerodromes through the next 24 hours. Moderate to breezy winds will diminish to light levels around sunset Thursday. Mostly cloudy skies and no rainfall are also likely. && .MARINE... Issued at 147 PM CDT Wed May 1 2024 Tonight through Thursday night...Moderate winds may yield periodic Small Craft Exercise Caution (SCEC) conditions. Conditions are expected to range between a moderate chop to choppy at the bay. Meanwhile, moderate seas are expected to continue with wave heights between 4-6 feet. Elevated seas will result in a MODERATE RISK for rip currents at the local beaches through Thursday. Friday through Wednesday...Moderate to occasionally strong southeast winds will prevail through most of the period across the coastal waters. Small craft caution conditions will be the dominant hazard. However, at times in the afternoon and evening, there will be marginal Small Craft Advisory conditions expected for the Laguna Madre and nearshore waters given the enhanced pressure and thermal gradients early next week. The rip current risk will remain moderate to occasionally high throughout the period. && .PRELIMINARY POINT TEMPS/POPS...

Office: CRP FXUS64 KCRP 020725 AFDCRP Area Forecast Discussion National Weather Service Corpus Christi TX 225 AM CDT Thu May 2 2024 ...New SHORT TERM, LONG TERM, MARINE... .SHORT TERM... (Tonight through Friday night) Issued at 225 AM CDT Thu May 2 2024 A largely uneventful forecast is expected during the short term period. Regional radar imagery indicates that deep convection has remained well north of San Antonio tonight. Therefore, the likelihood of thunderstorms across the Victoria Crossroads early this morning is very low (less than 20%). The only other low chance for precipitation will be Friday afternoon over La Salle and Webb Counties. This low chance will be dependent on whether there will be sufficient forcing from mesoscale boundaries to support the development of robust updrafts. Warm temperatures and abundant low level moisture will result in maximum apparent temperatures ranging from the mid 90s to low 100s today and Friday. These conditions will be a precursor to the increasing risk for heat related impacts next week. && .LONG TERM... (Saturday through next Wednesday) Issued at 225 AM CDT Thu May 2 2024 Key Messages: - Increasing risk of heat related impacts next week. Mainly dry conditions are expected through the long term period as moisture will be confined to a shallow surface layer...that will gradually get even more shallow as we head into next week. For Saturday, there is still the potential for an isolated storm coming out of the Sierra Madre and across into the Rio Grande Plains, however chances are low (10-20%). Beyond Saturday, winds above the surface shifting more to the south and southwest will bring drier conditions in the lower levels to leave only moisture confined to only within a couple thousand feet of the surface...and in the upper levels (maintaining some high cloud cover). This drier layer will also result in warming temperatures through next week. We'll start the week on Monday with highs around 100 west and in the upper 80s and lower 90s east. We'll quickly warm above 100 west through mid- week with highs approaching 110 by Thursday. If this verifies it would be our first high temperatures above 100 for the season. The risk of heat related illness will increase to moderate to high by mid-week, especially for vulnerable populations. While lower RH is expected west to keep heat index values near the temps, farther east heat index values will likely top 100 degrees. && .AVIATION... (06Z TAFS) Issued at 1025 PM CDT Wed May 1 2024 Storms have developed well north of the area this evening. However, there is abundant moisture in place across S TX that could interact with the tail end of the upper disturbance that is moving across Central TX overnight. There is a very low chance for convection to impact VCT during the early morning hours. Otherwise, MVFR conditions are expected across S TX overnight through Thursday morning. Brief VFR conditions are expected by early to mid afternoon across VCT, CRP, and ALI, then quickly becoming MVFR once again by early Thursday evening. MVFR conditions are forecast to persist across COT through much of the TAF period, while VFR conditions are expected across LRD by Thursday mid afternoon and then persisting through Thursday evening. Surface winds are progged to remain 5-15kt overnight before becoming gusty by mid to late Thursday morning into Thursday afternoon with gusts between 20-25kt. && .MARINE... Issued at 225 AM CDT Thu May 2 2024 A mainly weak to moderate onshore flow will persist through the weekend and into early next week.

Office: EPZ FXUS64 KEPZ 020533 AFDEPZ Area Forecast Discussion National Weather Service El Paso Tx/Santa Teresa NM 1133 PM MDT Wed May 1 2024 ...New AVIATION... .SYNOPSIS... Issued at 106 PM MDT Wed May 1 2024 A fairly persistent large scale weather pattern across the Southwestern U.S. will keep a fetch of very dry air over the Borderland for the rest of the week and through the weekend. Day to day temperatures will be quite steady, and average warmer than normal. Skies will typically be mostly clear, with plenty of sunshine. After a breezy day today, winds will slacken, with only occasional breezes in the afternoons through Friday, but then pick back up for the weekend and early next week. The primary concern, due to weather, over the next seven days will be compounding warmth and dryness, leading to drying of vegetation across the region, and fire weather conditions elevating to critical this weekend. && .DISCUSSION... Issued at 106 PM MDT Wed May 1 2024 A low-amplitude progressive wavy pattern will persist over the Western U.S. during this 7-day forecast period. This means generally a quasi-zonal pattern with passing minor ridges and troughs. With the pattern favoring flat, the troughs, with their associated moisture and dynamics will pass well to our north. For our forecast area, with will mean a continuation of the our stretch or precip-less weather. We have almost no precip, of any kind, in our forecast (with the exception of the east slopes of the SACs for Sunday). A deep dry environment will mean few clouds, plenty of sunshine, dry surface layers (low RH), warmer than normal temperatures, and deep mixing. Daily max/min temps should run pretty consistent from day to day, with only 2-4 degree changes through the period. Winds will slacken off after this evening as the currently upper trough passing to our north, crosses the Rockies, in the the Northern and Central Plains. We will see a 3 day stretch of generally light winds (for the season) with light afternoon breezes. Friday night through Saturday morning a front pushes in from the Plains over our NE and E zones. This does back in some Gulf moisture into the SACS, but it will be very shallow, and stay only briefly into the day on Saturday. We do have minor POPs and precip in for the eastern areas of the SACs and Guad escarpment of Otero Co., but the really don't believe we will see any realistic risk of showers or storms. The next Pacific trough approaches Sunday, and that will be reflected with and upward trend in winds as we see stronger winds aloft mix down in tighter mid-level gradients, and good mix down, and some lee surface troughing through central NM into Chihuahua, MX. Sunday could bring winds requiring a Wind Advisory. Monday and Tuesday follow with very similar winds that will border on additional Wind Advisories. There will almost certainly be RFWs posted for these three days, given RH in the 5-10 percent range. The associated trough swings through our area on Monday, but it looks to pass with insufficient moisture to produce any precip. Beyond Tuesday, it appears we settle back into a flat zonal pattern through late week, with more seasonally dry and warm conditions. && .AVIATION... (06Z TAFS) Issued at 1132 PM MDT Wed May 1 2024 VFR conditions persist through the forecast period. Other than FEW250 from time to time, SKC expected. W winds near 10kts expected through the AM, except for KELP which remains gusty due to downslope flow until daybreak. Gusts return for all TAF sites for the afternoon up to 20kts before subsiding late in the period. && .FIRE WEATHER... Issued at 106 PM MDT Wed May 1 2024 Fire weather season is in full swing, and the next 7 days ahead will ramp up those conditions from traditional, to elevated, to critical. We will continue with a deep and dry westerly flow pattern that ensures our region will remain warm and dry. The large-scale pattern will be low in amplitude, with the storm track positioned well north. This means only small changes in weather elements day to day. Temperatures will be largely steady, with only small day to day changes. Each day should have mild nighttime temps, and warmer than normal temps. Our RH will be pathetically low, overnight recoveries will be poor and struggle to rise above 30-35%. Daily minRH will be largely below 10%, and as low as 5% for most afternoons. The warm and dry air will mean deep instability and good mixing aloft. Winds will be moderate to low for the season through Saturday, with generally light overnights and mornings, and marginally, occasionally breezy afternoons. Sunday through Tuesday will be the time frame that we need to be focused on as a slow passing Pacific trough moves across the Western U.S. We will see increasing winds, while still being exceedingly dry. We are pretty certain these 3 days will be Red Flag Warning days. && .PRELIMINARY POINT TEMPS/POPS...

(Today through Friday Night) Issued at 247 AM CDT Thu May 2 2024 The bulk of the widespread showers and thunderstorms tonight have re- mained mostly north of a line from Lake Somerville to Lake Livingston. Unfortunately, this means that a lot of the same locations that got a bunch of rains earlier this week are getting yet another round. These storms (the initial development here along with the western activity, which is finally moving into the CWA), are expected to organize a bit more before finally tracking off to the east by mid to late morning. However, in its wake the associated frontal/outlflow/surface boundary will be left lingering across the FA. And so, with some daytime heat- ing, we could see more development later this afternoon. We could get another break from the storms by this evening, but hi-res models seem to be indicating yet another round of widespread showers and thunder- storms for late tonight through early Fri morning. Current models are tracking these storms more across the central and southern CWA during this period. So, with this in mind, have extended the Flood Watch through Fri aft- ernoon. This watch will likely be tweaked by later shifts...mainly to include counties south of the current watch. If all this goes accord- ing to the plan, we may see improving conditions (that is, decreasing POPs) by late Fri afternoon/evening. 41 && .LONG TERM... (Saturday through Wednesday) Issued at 247 AM CDT Thu May 2 2024 On Saturday afternoon, chance for showers and thunderstorms are still on the table, mainly for the Brazos Valley and Piney Woods region as another disturbance passes just to the north of the region. Although there is some capping in place during the morning hours, forecast sounding show it decreasing in the afternoon, and with fairly good instability, we could see some isolated to scattered activity developing over the aforementioned region. A similar set up is progged for Sunday, with chance of showers and thunderstorms, mainly north of I-10. We might even have the combination of locally driven storms along with the storms developing over Central Texas moving into our northern counties. It is important to note that with all the expected rainfall for today and Friday, some of these locations may have very saturated soils along with some ongoing localized area flooding and river flooding. Therefore, any additional heavy rainfall could result in additional minor flooding along with further rises in creeks, small streams, and rivers. Remember to never pass through flooded roadways. Things will be settling down more next week as mid to upper level ridging begins to build over Southeast Texas. Fairly tranquil conditions can be expected Monday into Wednesday but conditions will be warming up each day and highs will be reaching the upper 80s to low 90s with some locations possibly in the mid 90s by midweek. PWs will range between 1.3 to 1.8 inches and with dewpoints mainly in the low 70s, conditions will feel even warmer as well as muggy. In fact, might even see heat indices in the low 100s by midweek. 24 && .AVIATION...

Further south, are are getting reports of light rain. Hi-res models are keeping with the idea of the storms further west eventually moving east across our CWA overnight into Thurs morning (generally from a 10-15Z time frame). There is a potential for another round of SH/TSRAs by Thurs afternoon with conditions finally improving by tomorrow evening. Of note, there are indications that yet another round of storms are possible by late Thurs night/early Fri morning. 41 && .MARINE... Issued at 247 AM CDT Thu May 2 2024 Generally moderate onshore winds will prevail through much of the forecast period. Winds today may reach Advisory levels at times, but are expected to be mainly between 15-20 knots. For the next several days, seas will be between 4 and 6 feet over the offshore waters and between 2 and 5 feet over the nearshore waters. Bays may be slightly choppy at times. Also, strong rip currents along the Gulf facing beaches could develop at times. There is a chance for showers and storms, some could become strong, through Friday. During the weekend, much of the rainfall is expected to remain inland. Tranquil weather conditions expected next week as mid to upper level ridging builds over the region. 24 && .HYDROLOGY... Issued at 247 AM CDT Thu May 2 2024 There is ongoing river flooding over parts of Southeast Texas, particularly along portions of the Trinity and San Jacinto rivers. The following river points continue to remain at or above flood stage as of this morning: - Trinity River (Liberty): Major Flood Stage - Trinity River (Goodrich): Moderate Flood Stage - Trinity River (Riverside): Moderate Flood Stage - San Jacinto (New Caney): Moderate Flood Stage - Trinity River (Moss Bluff): Minor Flood Stage - Navasota River (Normangee): Minor Flood Stage Additional rainfall over the next few days, both over the area and upstream, may result in further water level rises and prolonged river flooding. Remember to heed any instructions from your local officials and to never travel through flooded areas or roadways. Please monitor updated forecasts via the NWS AHPS website and/or the new NWS NWPS webpage (https://water.noaa.gov/) as the river flood threat continues. 24 && .PRELIMINARY POINT TEMPS/POPS...

Office: LUB FXUS64 KLUB 020820 AFDLUB Area Forecast Discussion National Weather Service Lubbock TX 320 AM CDT Thu May 2 2024 ...New SHORT TERM, LONG TERM... .SHORT TERM... (Today and tonight) Issued at 313 AM CDT Thu May 2 2024 A welcome respite from severe storms awaits much of the forecast area today with the exception found roughly along and east of the Highway 83 corridor where a cold front and dryline intersection later today could fuel a few severe storms. Until then, we'll be contending with moist E-SE upslope flow this morning thanks to a large mesohigh in the wake of an MCS still churning over N TX as of 2 AM. This upslope flow will maintain some stratus over the region until a cold front drives south later this morning and scours this away. Clearing may struggle in our eastern column of counties where deeper moisture within a theta-E axis ahead of a dryline may serve as an obstacle to the front and effectively slow its progress. Any low clouds here should still scatter out by midday while allowing for MLCAPEs of 1500-2500 J/kg with minimal CIN. Sufficient deep layer shear of 30-35 knots within weakly cyclonic SW flow should help storms remain organized with some supercells once again on the table. However, there is more uncertainty than yesterday with storm development as some recent hi-res models are accelerating FROPA through most of the Rolling Plains by the afternoon which would shut the door on our 20-30 PoPs. This scenario will be revisited through the day and adjusted accordingly. As the cold front stalls this evening to our south, N winds will veer E and tug richer moisture westward onto the Caprock. This upslope regime looks favorable for stratus development overnight and potentially some fog. Various soundings exhibit stratus depths increasing to 1000-2000 feet thick which could be enough for drizzle at times, while higher aloft there exists a bit of ECAPE for thunder should any elevated ascent materialize. Kept PoPs very low after midnight and favoring our NE zones where moist isentropic ascent is a bit more evident than elsewhere. && .LONG TERM... (Friday through Wednesday) Issued at 313 AM CDT Thu May 2 2024 Post-frontal easterly upslope flow will continue through the day on Friday which will result in a continued increase in low level moisture. However, guidance is still not in agreement regarding the magnitude of this moisture return, with some models considerably more agressive in bringing a notable theta-e ridge northward into our area by early afternoon. There is also a growing signal of deepening surface troughing over eastern NM providing a dry downslope component near the TX/NM state line on Friday afternoon, and should this occur, a diffuse dryline may set up somewhere over the forecast area during the afternoon hours on Friday. A subset of synoptic models as well as some hi-res solutions do depict scattered thunderstorms developing along this feature Friday afternoon and evening, though capping and weak forcing aloft may limit coverage. Nevertheless, the signal is strong enough to maintain PoPs Friday afternoon and evening with highest chances along and east of I-27 with a severe storm or two not out of the question either. Attention then turns to the potential for more widespread showers and storms Saturday into Sunday with locally heavy rainfall also looking like a good bet over portions of the region. Early Saturday, initially west-southwesterly flow aloft will strengthen and back to a more southwesterly direction as a well-defined mid/upper level disturbance transits overhead. At the surface, a cold front will pass southward through the region early in the day before washing out over the southern South Plains or Permian Basin region during the afternoon. The presence of the remnant frontal boundary combined with robust low level upslope flow and increasing large-scale forcing for ascent is expected to result in the development of fairly widespread showers and thunderstorms late Saturday through early Sunday. Periods of heavy rainfall appear possible particularly late Saturday night off the Caprock where rich deep layer moisture (PWATs near 200 percent of normal) intersect with more coherent forcing associated with the difluent region of a southern stream jet streak. Overall, ensemble consensus suggests rainfall totals in excess of one inch will be possible over most of the Rolling Plains and SE TX Panhandle, with lesser amounts on the Caprock. Showers and storms will decrease in coverage from west to east throughout the day on Sunday, although PoPs do remain elevated off the Caprock for most of the day where moist upslope flow persists for longest. A fairly potent upper low will then pass eastward over the Intermountain West on Monday, but the track of this low still appears to be too far north to support widespread additional storm chances locally, except for the SE TX Panhandle and eastern Rolling Plains where a a couple of storms may be possible Monday afternoon before moisture exits eastward. Instead, most of the region is expected to see warm, dry, and breezy conditions return on Monday and persist through the middle of next week. && .AVIATION... (06Z TAFS) Issued at 1230 AM CDT Thu May 2 2024 MVFR stratus will continue to expand overnight on moist E-SE upslope winds, with CDS more likely to see this lower to IFR before daybreak. A FROPA and N wind shift later this morning will scour these clouds away and restore VFR, although this could prove a tougher task at CDS where moisture will linger. Not impossible that a few TS could redevelop near CDS during the afternoon along the front. && .LUB WATCHES/WARNINGS/ADVISORIES... None. && $$ SHORT TERM...93 LONG TERM....30 AVIATION...93

(Today through Friday afternoon) Issued at 219 AM CDT Thu May 2 2024 Once again, efficient moisture return and convective outflow from yesterday's storms has shoved the dryline back up against the western high terrain. However, the dryline will mix all the way into the western Low Rolling Plains and San Angelo's area this afternoon thanks to an upper trough ejecting from the Rockies into the north- central Plains. This keeps our weather significantly quieter than yesterday with most of the area just seeing a typical sunny, hot, and dry day. On the heels of this trough, it will help to push a cold front into the area today, and could start to nose into the northern Permian Basin in the late afternoon/early evening time frame. How this front evolves Thursday evening/night will play a large role in how Friday shakes out. That being said, the front and dryline interactions this evening will likely fire off a few storms, with a storm or two possible for Scurry/Mitchell counties. More importantly, the convective outflow from these storms would help push the front into our area and many of the high resolution models take the front all the way to the Pecos Valley. With uncertainty in how far the front makes it and how much it retreats/mixes north/east Friday, there is also a fair amount of uncertainty in both high temperatures (in the Permian Basin) and where any storms set up. For now, the thinking is a few more storms could fire off along the dryline or front, primarily across the far eastern Permian Basin. More details will likely come once it's determined what tonight's front will do. -Munyan && .LONG TERM... (Friday night through Wednesday) Issued at 219 AM CDT Thu May 2 2024 A potentially active weekend is ahead of us with the threat of more severe weather and flooding for portions of the area. Deep low level moisture will have returned to the area by Saturday morning with dewpoints >60F east of the higher terrain. At the same time, a cold front will be making its way south across the TX PH reaching our CWA boundary with LUB around mid morning. The front will slow its forward progress with daytime heating and height falls ahead of an approaching shortwave. As we reach peak heating by mid afternoon Saturday thunderstorms will develop along and behind the cold front. It's still a little far out in time to know where the front will be, but models are suggesting convective initiation somewhere across the Permian Basin. There will be plenty of instability and shear for storms to become severe with large hail and damaging winds the main threats. PWATs will be abnormally high for early May suggesting a threat for heavy rain and flooding, especially if storms train along the front. We could see some lingering clouds and showers Sunday keep tempertures down to around normal. Zonal flow aloft along with several storm systems passing to our north next week will mean a return to very dry and hot conditions. It's looking more likely we could see temperatures in the 100s across the Trans Pecos and Big Bend by mid week. Break out the sunscreen and swimsuits, summer is about here! && .AVIATION... (06Z TAFS) Issued at 1220 AM CDT Thu May 2 2024 Southerly return flow has overtaken all terminals and should persist through the overnight hours. This flow has brought low clouds in already to MAF, and guidance suggests MAF will be the only terminal to see the clouds. For now, they are at low MVFR CIGs but could dip into IFR levels at times throughout the night. All other sites remain VFR through the period. West winds take over shortly after sunrise and persist throughout the day. A cold front noses into the area by the end of the period which is set to bring a east- northeast wind shift. && .PRELIMINARY POINT TEMPS/POPS...

(This evening through Thursday) Issued at 232 PM CDT Wed May 1 2024 ...Severe Thunderstorms Possible Evening... Early this afternoon, a dryline was situated across far west Texas. Thunderstorms are expected to develop along the dryline during peak heating this afternoon, with storms moving eastward across the area during the evening hours. Initial storms are expected to be discrete, with supercells likely, then storms should become more linear with time as they push east across the area. Latest meso-analysis shows SBCAPES between 3000-4000 J/kg, which will support intense updrafts with any storms that develop. Effective shear is currently around 25 kts, but is expected to increase this evening as a shortwave approaches from the west. This will result in more widespread thunderstorm development later this evening. Very strong instability, coupled with steep lapse rates will support large to very large hail with any supercells initially, along with a tornado threat. Storms should gradually become more outflow dominant as they move eastward with time, with damaging winds becoming more of a concern. Storms should exit far southeast counties between 2 and 3 AM, although some lingering showers may remain for a bit longer across eastern portions of the forecast area. Thunderstorms will possible again Thursday afternoon and evening, as the dryline sets of across central sections and a weak cold front enters the Big Country during the late afternoon hours. In addition, several outflow boundaries will likely be present. Thunderstorm development will be possible along any of these features tomorrow afternoon into the evening hours. Very strong instability will occur east of the dryline and south of the front, along with deep layer shear between 35 and 40 kts. These parameters will support severe storms capable of producing large to very large hail, damaging winds and isolated tornadoes. The greatest risk for severe storms tomorrow will be across the eastern two thirds of the Big Country, eastern portions of the Concho Valley and the Heartland counties. As for temperatures, expect lows tonight in the mid and upper 60s, with highs Thursday mainly in the upper 80s and lower 90s. However, a few readings in the mid 90s will be possible across the western Concho Valley west of the dryline. .LONG TERM... (Thursday night through next Wednesday) Issued at 122 PM CDT Wed May 1 2024 Late Thursday afternoon, a dryline will be situated across our central counties. Meanwhile a cold front will be across the Big Country and is forecast to slowly move south through the evening hours, then stall somewhere across our central or southern counties. Isolated to scattered showers and thunderstorms are possible during the evening hours, ahead of the front and east of the dryline. Most of this activity should be confined to our eastern counties. A few strong to severe thunderstorms are possible, with large hail and damaging winds being the main hazards. Highs on Friday will be in the low to mid 80s across the Big Country, behind the weak cold front, and in the upper 80s to lower 90s elsewhere. Overall, drier conditions are forecast on Friday, although isolated to scattered showers and thunderstorms are possible with the remnant cold front in the region. Saturday into Sunday, West Central Texas will be in the southwest flow aloft, with a weak remnant cold front in the region. Showers and thunderstorms will be possible both days, with the higher rain chances across the Big Country. Locally heavy rainfall is possible with any thunderstorms. Highs will be slightly cooler, generally in the upper 70s to mid 80s. Drier conditions are expected next week with much warmer temperatures. Highs by Tuesday will be in the low to mid 90s, with highs on Wednesday in the approaching the upper 90s in some locations. && .AVIATION...

As this line of storms evolves, our damaging wind threat may increase through the early morning hours. Our greatest potential for severe weather will exist west of the I-35 corridor overnight tonight, although instances of severe weather will be possible into the morning hours as this line of storms moves through. Our main concerns with severe weather potential continues to include damaging winds and flash flooding, with lower potential for large hail and isolated tornadoes. Despite the rather progressive nature of this convective system, areas across South and Central Texas will see continued exacerbation of flooding issues with the current Flood Watch still set to last through this afternoon. Much of this activity will have exited our area to the east by this afternoon. However, this window of quiet weather will be short-lived as our next round of dry line convection fires off once again to our west. This activity will also be supported by a passing shortwave aloft, which will provide more large-scale ascent. This could very well play out in a similar fashion to tonight's activity, with organizing clusters of thunderstorms pushing in across portions of Central Texas through this evening into the early morning hours on Friday. Of course the environment will be supportive of thunderstorms across portions of North Texas as well, and severe weather will once again be on deck. Large hail and damaging winds will be the primary concerns, with a low- end tornado threat as well. Continual waves of heavy rainfall will likely continue the flash flooding concern across Central Texas as well. To echo our discussions as of late, please continue to monitor the weather over the next 12 to 24 hours as our active stretch of mid-spring weather persists in our forecast. Reeves && .LONG TERM... /New/ /Friday through Wednesday/ Friday through Sunday will remain unsettled with multiple opportunities for showers and thunderstorms. The good news is that the overall severe weather threat will be low. The passage of an upper trough across the Central Plains Thursday night will send a weak cold front southward Friday. The front is progged to move only partially through North Texas before retreating back to the north Friday afternoon and evening. Lift supplied by the front, in combination with larger scale lift from the passage of a subtle shortwave, will result in scattered showers and storms. Our confidence in the movement of the front is low so we will keep PoPs in the 20 to 40 percent range both Friday and Friday evening. There should be a brief lull in precipitation overnight Friday when the initial shortwave passes to the east and front temporarily moves north of the Red River. The front will return on Saturday once another shortwave in the northern branch of the jet stream pushes through the Central Plains. This secondary push will be stronger than the first, sending the front deeper into the CWA. Lift along the front will bring another chance of showers and thunderstorms, especially late Saturday night into Sunday morning when a shortwave rotates across the region. Once the shortwave passes to the east, storms will temporarily end but will return again on Monday with the approach of the dryline from the west and yet another shortwave. We will keep PoPs on Monday low for now since a cap of warm air will likely be in place. Once the early week shortwave moves to the east, the upper pattern will become more zonal which should limit convection, but with plenty of low level moisture in place, any subtle disturbance could produce a shower or storm. Temperatures Friday through the weekend will be near seasonal normals with highs in the lower and middle 80s and lows in the 60s. Southwesterly winds will return to about the western half of the forecast areas Tuesday and Wednesday pushing afternoon highs into the upper 80s and lower 90s. && .AVIATION... /NEW/ /06z TAFs/ Concerns...MVFR Ceilings and Thunderstorm Potential Overnight. A line of storms is currently racing across our coverage area to the west of the D10 TAF sites, with ongoing thunderstorms over Waco at the time of writing this discussion. These thunderstorms will push through the TAF sites around the 08-11z timeframe. As this moves through, expect a brief one to two hour window of westerly winds that could gust upwards of 35 knots. These will be short-lived and will quickly return light and southerly once this activity passes off to our east through Thursday morning. On top of this, MVFR ceilings will linger through much of the period with a brief window of clearing and VFR conditions on Thursday afternoon. There is low end potential for IFR ceilings across all TAF sites, but current confidence only allows for an inclusion in the Waco TAF. MVFR ceilings will return across all TAF sites as we move into late Thursday night. Additional potential for thunderstorms will also exist through early Friday morning, but this will be further assessed in the 12z package. Reeves && .PRELIMINARY POINT TEMPS/POPS... Dallas-Ft.
