.DISCUSSION...

Today...

The forecast continues to be on track with little change:

An upper-lvl high over the Southwest & Texas continues to
expand towards the Southeast. As the high progresses, heat indices
are expected to hit triple digits this afternoon, with increased
humidity. A cut-off low will track westwards, bringing PoPs of 40-
15% to our southeastern sites. This corridor of
moisture/precipitation will make its way northwards mid-week, which
will be elucidated on below.

This Week...

The aforementioned high will settle over the Southeast CONUS around
Tuesday, lingering through the rest of the week. Dangerous heat
concerns are expected to return as highs range in the mid/upper 90s
and heat indices reach 105-110F. As such, a limited heat graphic
will be messaged today. As the high settles, additional cut-off low
disturbances will traverse around the ridge, bringing deep moisture
and storm chances (25-50%) starting along the HWY 84 corridor. Mid-
week, rain chances will expand to the I-20 corridor and eastern MS
as the pattern lingers and wavers northward into the end of the
week.

.AVIATION...
(12Z TAFS)
Issued at 549 AM CDT Sun Aug 30 2026

VFR prevails throughout the period once again today. Mostly clear
skies with a few cirrus over most of area, with the west generally
remaining clear. There is a small chance for thin shallow mist
development over some central/southern sites this morning, which
will burn off an hour or two after sunrise. This will not effect
flight conditions, which will stay VFR. /OAJ/
