 - Medium to high (40-80%) chances of showers and storms this
   weekend, with the highest chances between midnight Saturday
   night and 1 PM on Sunday.

 - Probabilities for any severe storms remain low at this time
   due to weak instability, but will be monitored.

.DISCUSSION...
(This evening through next Tuesday)
Issued at 1225 PM CDT WED OCT 15 2025

Through Friday Night

A ridge axis remains nearby and will continue the dry, unseasonably
warm conditions across Central Alabama. The ridge axis will begin to
shift eastward on Thursday in response to an ejecting longwave
trough over the Four Corners region. As the pattern shifts, expect
generally sunny conditions with better chances of clouds on Friday
as a shortwave lifts across the Midsouth region. There will be some
scattered high level clouds on Thursday as the easterly increases,
but will only have limited affects on the temperatures. Temperatures
will reach the 80s each day with seasonably cool conditions at night.

Saturday Through Tuesday

The ridge axis will be well situated to our east by Saturday and
south to southeasterly low to mid-level flow will develop across
Central Alabama as the trough deepens over the Plains. This should
initiate gradual moisture advection in advance of an approaching
cold front which will be situated near the Mississippi River around
Saturday night into Sunday morning timeframe.

A severe threat will exist across the Midsouth region Saturday
afternoon, weak low-level lapse rates and meager instability should
limit the severe threat by the time the rain and storms reach our
forecast area overnight Saturday night into the morning hours of
Sunday. Nonetheless, a level 1 out of 5 severe risk may be warranted
as we get closer and are able to better assess the details. No need
to initiate messaging for that potential risk at this point.
Otherwise, the entire area should receive beneficial rainfall, but
amounts will be far from drought-busting. There are medium chances
of exceeding one inch of rainfall across the northern and
northwestern portions of the area while forecast amounts are less
than an inch elsewhere, largely due to the quick passage of the
front. We could potentially see a brief increase in convection in
the southeast late Sunday morning into early Sunday afternoon
that could increase rainfall totals in this area as well.
Essentially resulting in the areas in worst drought, seeing the
least rain.

Cooler and dry conditions are set to return on Monday as
northwesterly flow develops behind the frontal passage. Many
locations across the northern half of the area will see lows in the
40s Monday morning. Models are indicating the development of another
large ridge, becoming the dominant feature to maintain dry
conditions heading into next week.

.AVIATION...
(18Z TAFS)

VFR conditions with light winds for the period. Winds will shift to
more of a northeasterly after 15z Thursday.

.FIRE WEATHER...

Warm and dry conditions are expected to continue through Friday.
Minimum RH values of 25-35 percent are expected each afternoon
through Thursday before a moistening trend begins on Friday. 20 foot
winds should remain below Red Flag criteria. Outdoor burning remains
highly discouraged due to ongoing drought conditions.

Updated at 1259 PM CDT Wed Oct 15 2025 - Dry conditions will persist through Friday, with increasing rain chances this weekend. - The risk of life-threatening rip currents will increase on Friday, with a high risk on Saturday and Sunday. Before heading to beach, check the local conditions and follow the posted beach warning flags. && .DISCUSSION... Issued at 142 PM CDT Wed Oct 15 2025 The strong upper level ridge over the area causing the hot and dry conditions will slowly move east of the area through the end of the week. Meanwhile, sfc high pressure will shift off the east coast by Saturday allowing deep layer moisture levels to gradually increase as a southerly flow develops. Rain chances increase late Saturday into Sunday as an upper trough moves east across the plains and sends a cold front toward the area. The GFS has backed off on the strength of the trough and now stalls the front across central Alabama and Sunday in zonal upper flow. A stronger trough Tuesday into Wednesday finally pushes the front through the area. The Euro maintains a stronger trough and sends the front through Sunday afternoon/evening. The frontal timing differences lead to a wide range in POPs and temps between the models for this weekend into early next week. Due to the uncertainty, will maintain the NBM blend for now and see if better agreement develops on later runs. High temps remain above normal through Saturday and becomes uncertain after due to the frontal timing differences. Low temps will gradually increase through the week as moisture levels increase. /13 && .AVIATION... (18Z TAFS) Issued at 142 PM CDT Wed Oct 15 2025 VFR conditions will prevail through the next 24 hours. /13 && .MARINE... Issued at 142 PM CDT Wed Oct 15 2025 A light mainly southeasterly flow develops Thursday afternoon, with winds gradually increasing Friday into Saturday along with building seas. A light to moderate southeasterly flow to start the weekend will shift southerly and then southwesterly going into Sunday ahead of a cold front approaching from the northwest, and then northerly Sunday evening as the cold front passes through the area. /13 && .PRELIMINARY POINT TEMPS/POPS...
