.SHORT TERM... (This evening through Wednesday) Issued at 1233 PM CDT TUE SEP 30 2025
GOES Satellite imagery this afternoon reveals a low to mid level cloud deck moving across the eastern half of the state. The upper level pattern remains fairly active with a trough to our east and west, a weak ridge to our north, and a couple of tropical system off the east coast. Not expecting too much impactful weather across Central Alabama in the short term. We will continue with a low chance for showers and storms this afternoon and evening, generally for our eastern areas, as a pocket of H85-H5 vorticity rotates around the western periphery of a low over the Carolinas.
By Wednesday, Imelda is pushed out to sea as the series of upper troughs in place over the CONUS begin to nudge east. This will position a mid level ridge over the southeast. As a result, drier air will filter in across the region. With that said, we will hold onto some low end rain chances across our southern areas on Wednesday as a weak mid to upper level low tracks along the northern Gulf coast. Otherwise, look for highs in the mid to upper 80s tomorrow under mostly sunny skies.

.LONG TERM... (Wednesday night through next Monday) Issued at 1233 PM CDT TUE SEP 30 2025
High pressure remains in control through the end of the work week. Unfortunately these prolonged dry conditions will likely lead to the expansion of drought across Central Alabama. With that said, rain chances do return by Sunday as a weak low moves inland across the north Gulf coast. A healthy plume of moisture looks to accompany this feature which will hopefully help alleviate some of our ongoing drought conditions.
Temperatures throughout the long term remain fairly steady with highs in the mid 80s and lows generally in the 60s. The exception will be Friday morning as looks dip into the mid 50s as PWAts briefly fall to near 0.6-0.7".

.AVIATION... (18Z TAFS) Issued at 1233 PM CDT TUE SEP 30 2025
GOES satellite imagery reveals a low to mid level cloud deck resulting in MVFR cigs at MGM/AUO/ASN early this afternoon. Expecting VFR to return in the next couple of hours. Otherwise, VFR and light winds prevails at all other terminals through this TAF window. A few isolated showers/storms may develop this afternoon but confidence was not high enough to include in the TAF at this time.

.FIRE WEATHER...
The area should remain mostly dry, with minRH values will fall into the low to mid-30s by Wednesday. MinRHs in the mid 30 to low 40s are expected daily through the remainder of the work week. Given the sharp east shift in the tropical trends, no real moisture return is expected until next weekend, with only isolated rain chances the next seven days or so. Because of this, drought conditions will remain ongoing, with additional expansion possible given the lack of rain.
