.SHORT TERM...
(This afternoon through Thursday)
Issued at 220 PM CDT WED JUN 25 2025

This afternoon is the hottest afternoon that we should have for
the 7 day forecast with mid to upper 90s air temps and max heat
indices above 105 for most. Surface ridging remains present over
much of ERN Conus as well as in the upper levels for today.
However, with as hot as we are, we could still get a few tstorms
to develop through this evening. Any storms that do occur will
have the potential for become strong to severe with damaging winds
being the primary threat as well as some large hail as fuel will
not be a problem. Currently mentioning a 1 to 2 level out of 5
risk for severe tstorms through this evening for much of C AL.

The heat advisory in effect will continue for all counties through
7 pm. For the NW 1/2 of counties (along NW of a Sumter to Shelby
to Cherokee line), I have expanded the advisory to go through Thu
afternoon as well. SE 1/2 looks to be a tad lower for Thu, but
will monitor model trends for any additional changes. This change
will be due to the break down of the upper ridge as a low pressure
feature nudges toward us from FL. As a result, our afternoon
shower and tstorm chances will increase. This should in turn allow
for our highs to be a couple of degrees lower as well. Finally, some
marginally severe tstorms will be possible with heating.

.LONG TERM...
(Thursday night through next Tuesday)
Issued at 220 PM CDT WED JUN 25 2025

Guidance continues to trend wetter for our extended forecast. The
upper low, after migrating into the SE US should open up for Fri.
The upper levels are expected to remain unsettled through the
weekend and into the beginning of next week with overall moisture
continuing to increase. Rain chances will increase some for Fri on
into the weekend and further still for the beginning of next week.
With better chances for generally diurnally driven precip, our
highs should be a tad lower for the extended. While still hot and
humid, heat indices should remain below critical advisory levels.

Issued at 642 PM CDT WED JUN 25 2025

Conditions across central Alabama TAF sites will be largely VFR
through the next 24 hours. Will need to keep an eye on convective
trends this evening, and may need to issue later updates if storms
appear to be developing near or moving toward terminals.
Otherwise, mainly scattered/broken clouds above 10,000 ft
overnight, and scattered cumulus during the day on Thursday.
Perhaps a brief period of MVFR conditions due to light fog just
before or after sunrise.

NOTE: AMD LTD TO CLD VIS AND WIND has been added at MGM until
further notice due to comms issues.
