.SHORT TERM...
(Today through Saturday)
Issued at 1245 AM CDT FRI SEP 12 2025
A 500mb trough axis will move southeast of the area today
reinforcing the dry, northerly flow across Central Alabama. There
is one lingering storm near our northwestern counties at this
hour, but 1000-500mb RH will decrease from 55% to around 35-40%
this afternoon. Look for sunny skies with some fair weather cu and
temperatures ranging from the upper 80s east to lower 90s west.
Persistent and expansive ridging centered just to our west will
lead to near identical conditions on Saturday. Expect sunny skies
with temperatures in the upper 80s east to lower 90s west and low
humidity.

.LONG TERM...
(Saturday night through next Thursday)
Issued at 1245 AM CDT FRI SEP 12 2025
An Omega block will remain in place through the middle of next week
with the mid-level ridge axis centered generally over the
Mississippi River and high surface pressure encompassing the Eastern
CONUS. This will promote an extended period of hot and dry
conditions with no rain chances in the long term forecast.
Daytime temperatures will trend towards the mid 90s by Monday and
Tuesday with cool mornings in the 60s through the week. Heat
indices are expected to remain below Heat Advisory criteria as
humidity values decrease to around 30-40% during the hottest part
of the day.

.AVIATION...
(12Z TAFS)
Issued at 602 AM CDT FRI SEP 12 2025
One shower managed to hang on all night and reached TCL, producing
reduced visibility. These reductions should be short-lived, and
conditions will improve as the shower continues to track
southward. Otherwise, patchy fog may cause intermittent reductions
in visibility at the TAF sites this morning with VFR conditions
expected area-wide by 13-14Z. Mostly sunny skies are expected
during the day with high pressure in control across the region.
There will be a light northerly surface wind around 5 to 7 kts
then calm after 00Z.

.FIRE WEATHER...
Expansive ridging will continue to promote a hot and dry weather
pattern through our 7 day forecast period. Min RHs will drop into
the 30% range for most of the area again this afternoon and this
trend will persist into next week. The center of the high pressure
will build overhead over the weekend, leading to slightly higher
daytime highs. This will result in MinRHs dropping into the 30-35%
range for many locations on Saturday and Sunday. Although values
are currently forecast to remain above critical thresholds, drying
soils will likely lead to expanding drought conditions. Winds
should remain generally light with occasional gusts due to daytime
mixing.
