.NEAR TERM...
(Rest of today and tonight)
Issued at 139 PM CDT Mon Jul 27 2026

The heat maxima for today is still expected over northwest and
northern Oklahoma, where an Extreme Heat Warning remains in effect
for peak temperatures near 110 and heat indices neat 112. A Heat
Advisory remains in effect for the remainder of the area for
temperatures/heat indices up to 109.

Dewpoint temperatures continue to trend downward compared to recent
days, and with values in the 50`s across western Oklahoma this
afternoon. Across central Oklahoma and portions of western north
Texas, dewpoint temperatures will hover in the mid- to upper-60`s.

.SHORT TERM...
(Tuesday through Wednesday night)
Issued at 139 PM CDT Mon Jul 27 2026

Although temperatures will trend slightly downward in the short
term, the heat remains a concern with heat indices up to 109. A Heat
Advisory has been issued for the entire FA for Tuesday and will
likely be needed for Wednesday. A shortwave rotating around the
ridge could push a weak backdoor front could slide into portions of
northern Oklahoma late Tuesday afternoon or evening, and offers a
meager chance (less than 10 percent) of showers and thunderstorms
for a sliver of north-central Oklahoma by Tuesday night into
Wednesday morning. Very low rain chances also exist on Wednesday
night over northern Oklahoma ahead of another embedded shortwave
trough.

.LONG TERM...
(Thursday through Sunday)
Issued at 142 AM CDT Mon Jul 27 2026

The ridge will continue to meander westward into the desert
southwest by this weekend. This will bring a pattern change aloft
and stronger shortwaves and northwesterly flow aloft. A front is
still progged to move south across the area Friday, which will bring
a chance for "cooler" temperatures this weekend. By cooler, this
means a break from the triple digit heat and widespread Heat
Advisories across much of the forecast area with near normal
temperatures for the start of August (mid to upper 90s). There is
also a chance that precipitation could accompany the frontal
passage Friday, but these chances remain fairly low at this time.

.AVIATION...
(18Z TAFS)
Issued at 1234 PM CDT Mon Jul 27 2026

VFR conditions continue with many locations unlikely to see a
cloud in the sky over the next 24 hours. Main aviation concern
will be the slackening of the breeze tonight before a shift back
to south-southwest and increase in the morning.
