.NEAR TERM... (Rest of tonight and Wednesday) Issued at 1015 PM CDT Tue Sep 30 2025
Some light showers could be seen late this evening over NW GA that may clip portions of eastern Jackson and DeKalb counties. These are related to an upper wave located across the western Carolinas as outer bands from Hurricane Imelda stay more confined to the coast. Will keep low chances for rain over NE AL over the next few hours but otherwise a dry forecast is ahead during the overnight period as high pressure remains the dominating factor. The main concern tonight will be the potential for patchy dense fog, especially in and around river valleys. Overnight lows will fall to the low to mid 60s with mostly clear skies and light easterly winds.
The aforementioned disturbance will sink to our south on Wednesday and drier air will move into the area. Temperatures will be similar to what we saw today with highs in the mid to upper 80s. We should see plenty of sunshine today as high pressure settles over the northeast Atlantic.

.SHORT TERM... (Wednesday night through Friday) Issued at 1015 PM CDT Tue Sep 30 2025
Upper ridging and the aforementioned high will enforce a cooler and drier airmass into the late-week period as highs drop to the upper 70s/lower 80s across much of the area Thursday and Friday. A weak disturbance is progged to develop near the Gulf Coast late this week but any resulting showers/storms should be suppressed well south of the area. With that in mind, will maintain dry PoPs through Friday with sunny skies and light easterly winds. With the drier air in place and lack of recent rainfall, fog should become less likely each night.

.LONG TERM... (Friday night through Tuesday) Issued at 1015 PM CDT Tue Sep 30 2025
Surface high pressure situated along the coastal Mid Atlantic region will provide an easterly flow across the Tennessee Valley into the upcoming weekend. Under generally clear skies, seasonably mild to warm condition are expected. Cool low temperatures Friday night will range in the 50s. Highs both Sat/Sun should rise into the low/mid 80s both days. Milder night lows are forecast Sat/Sun nights with lows in the lower 60s.
An easterly flow rounding the high along the east coast, will become more from the SE during Sun, Mon, Tue. This will begin to tap lower level moisture from the Gulf and Atlantic, with an increase of clouds as we go into the next week. This will return rain chances to the area beginning Monday. With daytime heating and higher instability, some thunder is possible in the afternoon and evening hours with this activity. High temperatures the first part of next work week should range in the lower 80s, with lows in 60s.

.AVIATION... (06Z TAFS) Issued at 1239 AM CDT Wed Oct 1 2025
VFR weather should continue into the overnight for much of the area. Given less clouds over NW AL, have kept brief period of MVFR fog before daybreak at KMSL. Otherwise daytime heating should result in scattered fair weather cumulus from the late morning into Wed afternoon. Light winds overnight should become easterly generally less than 5kt for much of the day Wed, then become light and variable Wed evening.
