.DISCUSSION...
(Today through next Wednesday)
Issued at 1231 AM CST THU DEC 4 2025

Today through Friday

Patchy fog is possible this morning ahead of increasing rain chances 
by late morning/midday. Rain will move through the area in two waves 
from this morning through tonight and tomorrow morning. First, rain 
will filter in after 6 am, mainly across the southern half of 
Central Alabama. Maintained low chances across northern counties but 
potential for rain during the morning hours is much lower than 
across the south. Secondly, a larger rain mass will move in from 
Mississippi during the late afternoon, overspreading most of Central 
Alabama during and throughout the evening hours. Tonight will be 
soggy and rain chances remain high through Friday morning, 
especially across eastern and southeastern areas. Northwestern 
counties should see rain chances decrease by daylight Friday.

Saturday through Wednesday

Rain chances will linger through the weekend, especially across 
southern counties, as a conveyor belt of moisture moves across the 
area. Temperatures will warm into the mid to upper 50s Saturday and 
upper 50s to low 60s on Sunday. Rain chances will end Sunday night 
into Monday morning, and Monday looks to be cool and dry across much 
of the region. Monday night lows are likely to drop to near freezing 
across the southeast and below freezing across central and northern 
areas. Temperatures will rebound again Tuesday and Wednesday, with 
highs and lows slowly moderating.

rain. After a brief lull, another round of rain moves in after 
00Z. Ceilings will lower to IFR/LIFR through the night as this

.FIRE WEATHER...

Rain chances increase this morning, as another system works its way 
in from the northern Gulf. 1-2 inches of rainfall are expected 
through Saturday, with southeastern locations approaching 3 inches. 
Amounts will heavily depend on where the heaviest rainfall banding 
sets up. No flooding is expected, and the only impact across the 
region will be continued drought relief. Otherwise, MinRH values 
will remain above 50% through Monday, and fire weather concerns will 
remain limited through the weekend.
