...New AVIATION...

.KEY MESSAGES...
Issued at 1258 PM CDT SAT JUN 20 2026

- Flooding: A Flood Watch is in effect for much of Central Alabama
  through this evening due to a high chance for additional heavy
  rains falling on already saturated soils. Flash flooding will be
  possible along and south of the I-22 corridor, stretching
  eastward to the Birmingham Metro area and the I-20 corridor.

- Heat: Heat index readings approaching 100 degrees are forecast
  beginning Monday and Tuesday.

.DISCUSSION...
(Today through Friday)
Issued at 457 AM CDT SAT JUN 20 2026

How about a good ole fashioned forecast update during the
overnight shift? It was certainly needed tonight, as the short-
term forecast has trended much more active over the past
12 hours. The latest CAMs hot off the press this morning are in
pretty good agreement with the development of widespread showers
and storms over much of the CWA along a stalled frontal boundary
currently draped across Central Mississippi and Alabama.  Current
surface analysis indicates that the I-20 corridor is currently
"wedged" in between higher pressure along the central Gulf Coast
and Tennessee Valley region north of the stalled front. A mid-
level shortwave impulse moving in from the west will provide
plenty of synoptic lift aloft, combined with convergence at 700mb
and a saturated profile from 1000-500mb.  One or more MCVs in the
area could also trigger additional development. PWATs of 2+
inches are also expected to advect eastward into the CWA as 925-
850mb moisture transport brings in tropical moisture from the
southwest.

As storms develop and slowly move east-southeastward this morning
through this evening, the threat for flash flooding will increase
as storms are expected to not only move across similar areas, but
also where soils remain saturated from recent rounds of heavy
rain. Following coordination with WPC overnight, we've decided to
go ahead and issue another Flood Watch for most of the CWA
through this evening. Any torrential downpours that occur with
rain rates of 2-3 inches per hour will cause flooding to occur at
a much faster pace due to the water-logged soil conditions. We'll
have to watch the hydro desk very closely throughout the day
today.  CAMs have indicated this morning that heavy rains may
develop along and south of a line stretching from the I-
22 corridor to the Birmingham Metro and eastward to the I-
20 corridor.  If some of the CAMs verify, we'll need to watch for
a flash flood/urban flood potential within some of the higher
population centers, such as Tuscaloosa, Jasper, and Birmingham
through the first half of the day today.  Based on the storm
development trends we observe today, we can determine if the
watch will need to be extended further into the evening for the
southern half of the CWA.  The northern counties within the watch
could be trimmed back a little earlier in the day as drier air
aloft filters in as 500mb flow becomes northwesterly this
afternoon.

.AVIATION...
(18Z TAFS)
Issued at 1258 PM CDT SAT JUN 20 2026

As convective development occurs, ceilings are forecast to drop
once again with prevailing SHRA which will limit visibility at
times as coverage increases. Impacts are already being felt at
BHM and TCL with EET up next. Interests should expect frequent
amendments and potentially an addition of prevailing TSRA for
terminals through this afternoon. TEMPO TSRA was also added in
for KAUO and KMGM for later this afternoon, but forecast
confidence is a little lower in terms of timing and overall storm
coverage. Following TSRA/SHRA ending this evening, VFR conditions
can be expected with the potential for lower ceilings returning
once again. Winds will remain light and variable outside of
thunderstorms.  More showers and storms after 15z on Sunday, but
more than likely after 17z.

Note: Metars from AUO are coming through but observations are
missing data. Therefore, AMD NOT SKED has been added for this
set.

.FIRE WEATHER...

High rain chances continue as we will remain in a wet pattern
through early next week. Ample moisture in place will keep MinRH
values above 50% through the entire forecast period. Elevated
fire weather concerns are not expected at this time.
