.NEAR TERM...
(Rest of today and tonight)
Issued at 120 PM CDT Wed Jul 22 2026

A cool front will provide minimal relief for most of us this
afternoon. Highs behind this boundary are still expected to be in
the upper 90s, while locations ahead of the front will reach
triple digits. Heat indices for some locations along the Red River
will reach 115F this afternoon.

There is a low chance for a few thunderstorms to develop across
southwestern Oklahoma and adjacent western north Texas this
evening, primarily in the vicinity of the stalled frontal
boundary. Main impacts with any activity will be lightning.

.SHORT TERM...
(Thursday through Friday night)
Issued at 120 PM CDT Wed Jul 22 2026

The aforementioned front will wash out Thursday, and winds are
expected to come back around to the southeast. Hottest heat
indices will be across southwestern Oklahoma and western north
Texas Thursday afternoon, where a heat advisory will be in effect
through the afternoon and early evening.

A shortwave trough will move across the central Plains Thursday
and will dive southward across the southern Plains Thursday night.
Storm chances will increase Thursday night into Friday morning
across the northern half of the area. Additional thunderstorms are
possible Friday afternoon and evening across the area as the wave
moves across the southern Plains. Heat indices Friday will still
be between 105-110 F Across most of the area, so expect additional
heat headlines in the coming days.

.LONG TERM...
(Saturday through Tuesday)
Issued at 141 AM CDT Wed Jul 22 2026

The ridge will expand back over the region this weekend into early
next week, maintaining triple digit highs over the area and
squashing precipitation chances to near zero. Higher humidity may
also bring a return of heat indices near or over 110 degrees for
much of central/eastern OK by Sunday and Monday. Unfortunately,
long range ensemble data suggests strong upper ridging is likely
to remain in place through the middle and potentially through the
end of next week, favoring a continuation of above normal
temperatures over the area and keeping rain chances very low.
