.NEAR TERM... (Today) Issued at 241 AM CDT Mon Sep 29 2025
High pressure extends from the Northeast, through the OH Valley, into the Midwest, and down into the Southeast. Tropical Storm Imelda remains down in the Bahamas, but streaming cloud cover up into the Southeast`s Atlantic coast. Satellite is showing a few mid to upper level clouds sliding into the TN Valley at this hour, however the vast cloud shield will remain off to our east today leaving us with mostly sunny to partly cloudy skies. Dry conditions are expected today but monitoring satellite and sfc obs for patchy fog development especially in and around river valleys this morning. Otherwise, today will be warm with highs in the lower 80s in NE AL and the mid to upper 80s elsewhere, which is ~5 degrees higher than normal.

.SHORT TERM... (Monday night through Wednesday) Issued at 1053 PM CDT Sun Sep 28 2025
Upper ridging will become more amplified in the short term period as the tropical systems begin their sharp turn east and large scale subsidence sinks south over the eastern CONUS. This will result in near seasonable highs in the low/mid 80s and lows in the low to mid 60s. There is a very low chance (less than 20%) a stray shower or two could wander over eastern AL Tuesday afternoon as Imelda pivots east, but the majority of the area should remain dry with mostly sunny to occasionally partly cloudy skies depending on how far west the outer bands of Imelda track.

.LONG TERM... (Wednesday night through Sunday) Issued at 1053 PM CDT Sun Sep 28 2025
There will be little chance in the overall synoptic pattern as we head through the long term period. Some good news for those hoping for cooler temperatures is that with high pressure settling over the Northeast as we head toward the end of the week, cooler and drier air will be pushed southwest into the local area. Highs will drop into the upper 70s in some locations, especially in the higher terrain areas, with temps in the lower 80s elsewhere. With the drier airmass in place, we should see abundant sunshine for the later half of the week and pretty ideal weather for any outdoor plans. Overnight lows will fall as well, approaching the lower 50s Thursday and Friday nights. It does not look like we will hit the 40 degree mark quite yet, but it will feel noticeably cooler later this week!

.AVIATION... (06Z TAFS) Issued at 1218 AM CDT Mon Sep 29 2025
VFR conditions are expected to prevail at KHSV and KMSL through the TAF period. A batch of mid to upper level clouds are currently sliding westward and may effect KHSV, but VFR conditions will remain. Still low confidence on fog development tonight so kept it out of the TAF and will continue to monitor trends.
