.KEY MESSAGES...

 - Scattered showers/storms continue overnight.

 - Heat advisory for southeast Oklahoma today.

 - Less hot and dry for the latter half of the week.

.NEAR TERM...
(Through Wednesday)
Issued at 1206 AM CDT Wed Aug 20 2025

Storms continue to shift southward, leaving a slightly cooler
airmass in their wake. CAMs suggest some additional development will
be possible before sunrise across southwest Oklahoma and parts of
north Texas (aided by outflow from previous storms). Severe risk
should remain low.

Wednesday will be slightly cooler across most of the area (highs in
the mid 90s). Heat advisory for southeast Oklahoma still looks on
track as the hot, moist airmass is slower to get overturned in this
area.

Diurnally driven storms will be possible again this afternoon near
and south of the Red River. Depending on how far the front advances,
this activity may end up farther south keeping our forecast area
mostly dry.

.SHORT TERM...
(Wednesday night through Friday night)
Issued at 1206 AM CDT Wed Aug 20 2025

Thursday and Friday, we`ll be between systems, so "less hot" (highs
in the low to mid 90s) and dry. By Thursday, enough of the cooler,
drier air should have moved in to keep us out of heat advisory
territory.

.LONG TERM...
(Saturday through Tuesday)
Issued at 1206 AM CDT Wed Aug 20 2025

Over the weekend, a shortwave will approach, bringing low rain
chances to northern Oklahoma and keeping temperatures near normal.

Another wave will move through early next week, bringing a stronger
dose of cold air (temperatures below the 25th, possibly 10th,
percentile of climatology) and higher rain chances.

.AVIATION...
(12Z TAFS)
Issued at 614 AM CDT Wed Aug 20 2025

Showers and storms this morning are continuing to push southward
with DUA/SPS being the only sites affected through the next hour
or so. Some areas of patchy fog are developing this morning in the
wake of the overnight convection, however confidence is too low on
exact area and persistence of the potential lower visibilities.
Otherwise, VFR conditions are expected through the period with
north-northeast winds. The chances for storms this afternoon
remains low, but an isolated storm cannot be ruled out.
