.NEAR TERM... (Rest of tonight and Sunday) Issued at 1038 PM CDT Sat Oct 4 2025
A troughing west and ridging east upper pattern continued over the greater CONUS. Even with upper ridging in place over the east coast, a weak upper level low spinning south of AL/FL was spreading clouds over parts of the SE states, with a few showers (mainly over the Gulf of America). More inland from the Gulf coast (say Birmingham and northward), it was too dry in the low/mid troposphere to support shower activity at this time. This could change later during Sunday, as more of this moisture seeps further inland. A weak area of low pressure trying to form south of the TX/LA coast should remain over that portion of the Gulf into late Sunday.
For tonight, another dry and cool/mild period is expected. With relatively dry air in place, low temperatures will cool from the low/mid 60s with ESE winds of 5-10 mph, with a few higher gusts at times. A return of more high altitude moisture will make for partly cloudy skies Sunday afternoon. High temperatures should rise into the low/mid 80s, with SE winds of 5-15 mph in the afternoon.

.SHORT TERM... (Sunday night through Tuesday) Issued at 1038 PM CDT Sat Oct 4 2025
Shower activity along the Gulf coast on Sunday should slowly creep inland Sunday night into Monday. The models for the most part were suggesting that lower end chances of showers returns sometime late Sunday into Monday. Output from the NAM and FV3 were rather skimpy with rain coverage. The new NBM run has kept similar coverage regarding rain chances late Sunday into Tuesday.
Temperature forecasts...rather mild night time conditions are expected Sunday and Monday night, with lows in the low/mid 60s. Despite cloud coverage and rain chances, high temperatures on Monday should rise into the upper 70s to lower 80s, and into the low/mid 80s Tuesday. These values may be a bit lower if chances of shower coverage becomes greater.

.LONG TERM... (Tuesday night through Saturday) Issued at 1038 PM CDT Sat Oct 4 2025
Upper level ridging now over the coastal Mid Atlantic will slowly build to the SW during the early portion of next week. Troughing that was producing unsettled weather over parts of the northern Rockies should also weaken and move Ontario/Quebec by the mid week. This will essentially bring a more zonal upper flow pattern across much of the Lower-48 towards the middle of next week.
A cold front will be approaching the area from the NW late Tuesday, and move across the Tennessee Valley on Wednesday. With more clouds and low rain chances (20-30%), highs temperatures for the mid week should be a tad cooler into the upper 70s and lower 80s. A bit cooler Wed night with lows in the upper 50 and lower 60s. An airmass change will make for slightly cooler conditions for the second half of next week, with highs in the mid 70s to around 80, and lows in the mid 50s to lower 60s.
Limited lower level moisture return before the front moves across the region, will help keep rain chances and amounts on the low side. For the Thu-Sat timeframe, spotty rain chances should continue Thursday, with Fri/Sat trending dry and worsen the on- going drought.

.AVIATION... (06Z TAFS) Issued at 1152 PM CDT Sat Oct 4 2025
VFR conditions are forecast through the TAF period. The main concern will be an increase in easterly winds through the morning and especially by Sunday afternoon. Sustained winds around 10 knots are anticipated, with wind gusts to around 20 knots or so. This will also persist through the evening. Additionally, LLWS might become a concern by around 6Z Sunday night, but this will be reassessed in later updates. Also, expect an increase in mid to upper level cloud cover through the day. Any precipitation that occurs will likely remain to our south and southeast and not affect the terminals.
