Widespread dense fog has formed within a weak pressure gradient

Rain-free and much cooler conditions will arrive Wednesday night
and continue through Saturday morning.

An extended period of enhanced rain chances should begin Saturday

becomes established at 500 mb across the southern CONUS.

Updated at 1027 PM CST Tue Nov 25 2025 - Strong offshore flow will create hazardous conditions for small craft across portions of the marine area Wednesday night into Friday morning. - There is a moderate risk of life threatening rip currents at area beaches Wednesday, then a high risk is anticipated this weekend. && .DISCUSSION... Issued at 1027 PM CST Tue Nov 25 2025 A cold front has advanced into the western portion of the area and will continue through the remainder of the area overnight. Oddly enough, the frontal boundary is fairly weak at the moment and patchy fog, dense in some locations, has developed over southeast Mississippi and portions of southwest Alabama. The fog is expected to dissipate overnight as cooler and drier air begins to move into the area in the wake of the front. Dry conditions are expected for Wednesday through Saturday as a large surface ridge shifts across the region in the wake of the cold front. A deep surface low develops over the Plains on Saturday then moves off across the Great Lakes region and in the process brings a cold front through the forecast area on Sunday. A series of shortwaves move across the region Saturday night ahead of the approaching front, and while it appears that shear values would be sufficient to warrant concern, instability looks to be sorely lacking and precluding the potential for strong storms. For Sunday, shear values are currently indicated to be low, and it's not clear how much instability will be able to develop over the area before the front moves through. Will need to monitor at this point. Highs on Wednesday generally range from the mid/upper 60s well inland to the lower 70s closer to the coast. Highs on Thanksgiving Day range from the mid/upper 50s well inland to the lower 60s closer to the coast. Highs on Friday will be a bit cooler, then temperatures moderate through Sunday to highs in the mid 60s to around 70. Highs trend cooler Monday into Tuesday, with highs on Tuesday ranging from the mid 50s well inland to the mid 60s at the coast. Lows Wednesday night range from the mid 30s well inland to the lower 40s at the coast, then lows Thursday night range from around 30 well inland to near 40 at the coast. Overnight lows trend by Saturday night to range from the lower 40s well inland to the mid 50s at the coast, then in the wake of Sunday's cold front, lows by Monday night dip to around 40 well inland to around 50 at the coast. A moderate risk of rip currents on Wednesday will be followed by a low risk through Friday. A high risk of rip currents is expected for this weekend. /29 && .AVIATION... (00Z TAFS) Issued at 601 PM CST Tue Nov 25 2025 A broken line of storms near the I-65 corridor will continue moving east and should be mostly clear of the region by 06-08z. Brief periods of IFR conditions possible in any stronger storms. Otherwise, there will be a band of MVFR cigs ahead of the convection that will clear out once the convective line moves through. VFR conditions will become predominate after midnight into early Wednesday morning. Winds will shift out of the north/northwest across the area as a cold front moves through late tonight. The front should be east of the area by 12z Wednesday. 34/JFB && .MARINE... Issued at 1027 PM CST Tue Nov 25 2025 A moderate northerly flow develops overnight into Wednesday morning, then a moderate to strong offshore flow follows for Wednesday night. The offshore flow diminishes somewhat on Thursday then strengthens mainly over the open Gulf waters Thursday night. A northeasterly flow develops on Friday then becomes southeasterly on Saturday. A Small Craft Advisory is in effect for most of the marine area Wednesday night then tapers to over the 20-60 nm portion for late Thursday morning through Friday morning. May need to consider adding the near shore waters to the Small Craft Advisory late Thursday night into early Friday morning. /29 && .PRELIMINARY POINT TEMPS/POPS...

(06Z TAFS) Issued at 1129 PM CST Tue Nov 25 2025 A mixed bag of VFR to LIFR conditions across the area. VFR conditions are present mainly east of I-65 across south central Alabama into the western Florida panhandle. Patchy fog and low ceilings have developed across the I-65 corridor ahead of a approaching cold front from the northwest. Fog should linger for the next hour or two until the front progresses through the area leading to VFR conditions returning to the area. Winds will quickly turn north-northwesterly behind the front and increase during the day to around 15 knots gusting to 20 knots. VFR condition should persist through the remainder of the forecast.
