.DISCUSSION...
(Monday through next Sunday)
Issued at 1026 PM CDT SUN JUN 21 2026

Water vapor imagery this evening reveals an upper level shortwave
cutting across the Plains. This feature will be one of the forces
behind our next threat for strong to severe storms. At the
surface, a cold front can be analyzed across the Southern Plains.
This boundary will slowly sag south, eventually stalling across
the state sometime Monday night into Tuesday morning. If we take
a look out to our west, a cluster of storms is beginning to
develop back across Missouri. This activity will move south
overnight, likely weakening as it moves through Mississippi. With
that said, our northwestern counties may receive a glancing blow
from any lingering activity during the morning hours. We will
need to keep an eye out for any convective development through
the day as outflow boundaries are likely to be lingering across
the region. CAMs continue to hint at a line of storms developing
just off to our northwest during the mid afternoon hours, moving
through Central Alabama during the evening and overnight hours.
Ample instability and bulk shear around 35 knots would support
the threat for strong to severe thunderstorms with damaging winds
being the primary concern. With that said, guidance is
highlighting a corridor of enhanced SRH (200-300 m2/s2) during
the late afternoon and early evening hours, mainly across the
northern half of the state. This will pose a brief threat for an
isolated tornado or two. As a result, there is a Slight Risk
(Level 2 of 5) for Severe Storms across our northwestern counties
and a Marginal Risk (Level 1 of 5) for most of Central Alabama.
Given saturated ground conditions, even non-severe winds could
result in downed trees; remain weather aware on Monday,
particularly across the northern half of the area. In addition to
the severe threat, we will also have a Slight Risk (Level 2 of 4)
of Excessive Rainfall for the northern half of the area on
Monday. These storms should be moving at a decent rate so that
should help limit our flooding threat. However, a fully saturated
profile and a deep warm cloud depth will lead to high rain rates
with this activity, leading to isolated instances of flash
flooding.

Through the remainder of the work week, upper-level ridging will
establish control to the west, resulting in northwest flow aloft.
Several H5 shortwaves are expected to rotate through this regime,
maintaining elevated rain chances. The aforementioned cold front
will linger through the week maximizing low-level convergence and
increasing chances for showers and thunderstorms. As we head into
the weekend, rain chances begin to lower as a subtropical ridge
takes control. Otherwise, hot and humid conditions will persist,
with highs in the upper 80s to low 90s and heat indices
approaching 100 degrees early next week.

.AVIATION...
(06Z TAFS)
Issued at 234 AM CDT MON JUN 22 2026

For the overnight hours, have kept a persistence forecast,
keeping ceilings lowering to MVFR, then to IFR ceilings before
daybreak. Ceilings are still expected to lift back to VFR during
the late morning hours, with southwesterly winds increasing.
Gusts from 20-25 knots will be likely through the afternoon.
SHRA/TSRA development will be monitored from the northwest that
will be moving into Central Alabama during the day today.
Greatest chances for TSRA will remain across the northern
terminals of BHM/EET/TCL, with lower confidence for MGM and AUO
into the evening hours. VFR conditions are forecast into the
evening hours tonight after showers and storms dissipate.

Note: METARs from AUO are available but missing data; therefore,
AMD NOT SKED continues.

.FIRE WEATHER...

High rain chances continue as we will remain in a wet pattern
through the work 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.
