.SHORT TERM...
(Tonight through Tuesday night)
Issued at 1225 PM CDT Mon Jun 29 2026

The upper level ridge that has been entrenched across the
southern US over the past couple of days is forecast to shift
northeastwards through Tuesday. The ridge is forecast to become
centered over the Ohio River Valley. This will help to keep our
daily high temperatures in the 90s as well as keeping the heat
index near the century mark.

A retreating dry-line across west Texas will be the focus for
thunderstorm development this afternoon and Tuesday afternoon. Hi-
res models show these storms staying just west of Val Verde County
both days. With the shift in the upper ridge, there is a signal
for a few streamer showers for portions of the eastern Coastal
Plains and I-35 corridor early Tuesday morning in a few hi-res
models. Will introduce low-end POPs to address this potential.

Overnight lows both tonight and Tuesday night will be in the mid
to upper 70s for the majority of the area.

.LONG TERM...
(Wednesday through next Monday)
Issued at 1225 PM CDT Mon Jun 29 2026

The upper ridge is forecast to remain over the Ohio River Valley
through Thursday. With southerly flow, this will keep the potential
for morning streamer showers possible each morning. On Friday into
Saturday the upper ridge breaks down as flow becomes zonal then
northwesterly. This will allow a dryline to make more easterly
progression and could allow for showers and thunderstorms to reach
portions of the service area.  Increased southerly flow will also
result in afternoon heat index values in to 103-107 range.

(00Z TAFS)
Issued at 612 PM CDT Mon Jun 29 2026

MVFR CIGs are expected to develop again tonight with initial
development near SAT/AUS around and after 06Z with some spread
toward DRT and vicinity around 11Z before clouds clear and VFR
prevails again by the afternoon. Overnight conditions favor some
dust currently concentrated at FL040-FL080 to persist closer to the
surface overnight. This may cause marginal reductions to VSBYs to
around 6SM as winds weaken slightly before clearing out in the
morning as breezy southeast winds restrengthen.
