.NEAR TERM...
(Through Friday)
Issued at 147 AM CDT Fri Jul 24 2026

Lingering showers and weak storms may continue across portions of
northern into central Oklahoma Friday morning from the decaying MCS
last evening. May see some gusty winds and small hail with any
stronger updrafts with the activity, but overall should remain sub-
severe and weak.

The upper ridge will pivot westward today with a passing shortwave
to the north. Temperatures will still be hot in the 90s to triple
digits, with the hottest temperatures across western Oklahoma into
western north Texas. Southerly winds on the western periphery of a
surface high over the Gulf states will provide a plume of low-level
moisture from the Gulf with increasing dewpoints into the 70s. This
will give way to widespread heat indices near 105-110 degrees across
the forecast area. A Heat Advisory remains in effect for the entire
forecast area from noon to 8 PM.

A weak surface trough with hot temperatures and increased low-level
moisture will give way to scattered afternoon convection across the
Texas Panhandle and into the eastern portions of the Oklahoma
Panhandle. An embedded shortwave in the northwesterly flow aloft may
help to drive storms southeast into northwest and western Oklahoma
through the afternoon/evening hours. A few storms may become strong
to severe with locally damaging wind gusts as the primary hazard.
Convection will decay as it pushes into Oklahoma late tomorrow
evening, but a few outflow boundary`s overnight may help to initiate
new shower/storm development across portions of Oklahoma early
Saturday morning. This activity would likely be sub-severe with
gusty winds as the primary hazard.

.SHORT TERM...
(Friday night through Sunday night)
Issued at 147 AM CDT Fri Jul 24 2026

Saturday, the upper ridge will build back eastward towards the
Colorado Rockies and into Kansas. This will bring widespread warmer
temperatures closer to triple digits across much of the area.
Dewpoints will continue to linger in the upper 60s to lower 70s and
bring widespread heat indices of nearly 105 to 110 degrees across
the area and some areas in northern and central Oklahoma may
approach 110 to 115 degrees. A Heat Advisory will likely be needed
for Saturday with a potential for an Excessive Heat Warning across
portions of northern into central Oklahoma. Sunday will be even
hotter temperatures as the ridge builds more over Oklahoma, but
there will be some relief in the 70s dewpoints due surface troughing
developing across the Rockies. Heat indices will still range 100 to
110 degrees across the area. All in all, there is a high to extreme
risk for heat related illnesses this weekend.

With the ridge moving eastward towards Oklahoma this weekend, the
flow aloft will become east-northeasterly and limit precipitation
chances through the weekend.

&&

.LONG TERM...
(Monday through Thursday)
Issued at 147 AM CDT Fri Jul 24 2026

Next week will feature continued heat as the upper level dome of
high pressure continues to linger over much of the Southern Plains.
Heat indices will likely range from 100 to 105 degrees across most
of the area each day through the week, with some areas that may
breach 105 to 110 degrees. Therefore, heat will remain the main
message through the week with continued risk for heat related
illnesses.

Towards the tail end of the week, the ridge may retreat westward and
open the door for northwesterly flow aloft. This could bring a
return to precipitation chances, but chances remain low at this time.

.AVIATION...
(12Z TAFS)
Issued at 700 AM CDT Fri Jul 24 2026

Showers and a few embedded thunderstorms continue to move
eastward across northern Oklahoma this morning. KPNC and KSWO will
have a chance of showers/storms this morning with the potential
for activity as far south as KOKC and KCSM.

Light and variable winds this morning will become
south/southeasterly later this morning.
