(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!
