.SHORT TERM...
(This evening through Sunday)
Issued at 550 PM CST SAT FEB 22 2025

A shortwave trough will move east tonight and approach our area
by Sunday. Surface high pressure currently over the region will
slide east will become centered across the Southern Appalachians,
while a coastal low will become positioned just south of New
Orleans Louisiana. This will result in increasing clouds by Sunday
morning in the south and increasing rain chances in the afternoon
across the southern half of the area.

.LONG TERM...
(Sunday night through next Friday)
Issued at 221 PM CST SAT FEB 22 2025

Upper level shortwave trough moving along the Gulf coast will
continue to spread rain across the southern half of the forecast
area Sunday night. Once that shortwave moves off to the east on
Monday, we will return to a dry forecast for several days. The
next chance of rain comes Wednesday night and/or Thursday, when
another upper level shortwave quickly swings through the base of
the longwave trough in the eastern half of the country and helps
drive a surface cold front through the southeast. GFS is a bit
more bullish with the moisture than the ECMWF at this point, and a
model blended POP of 20 to 40 percent seems about right during
this time frame.

.AVIATION...
(00Z TAFS)
Issued at 550 PM CST SAT FEB 22 2025

VFR conditions will prevail through 18z, before we start to see an
increase in clouds as well as lowering. Included Prob30s for 4SM
RA after 21z for the south and west as a shortwave begins to move
through the area. Questions in regards as to how far north the
rain makes it, so left the Prob30s out of BHM, ANB and ASN.

.FIRE WEATHER...

A storm system moving along the Gulf coast will bring an area of
rain into the south half of central Alabama on Sunday into Sunday
night. High pressure will build back in and bring rain free
conditions for the start and middle of the work week. There are no
obvious wind or RH concerns through the period.
