KEY MESSAGES

Updated at 1030 AM CDT Thu Jul 23 2026

- Dangerous heat expected to persist most days into at least the middle of next week.

- Thunderstorm chances today into Friday, mainly for northern/western OK.

NEAR TERM

(Today and tonight) Issued at 1030 AM CDT Thu Jul 23 2026

Mid-level ridge is centered over west Texas and a progressive shortwave crossing Kansas has provided for a few showers over Kay County this morning. A pseudo-warm front (nearly stationary) is noted on mesoanalysis over northern Oklahoma and a dryline west of our FA. Another hot day is expected with high temperatures mostly reaching the mid-90's to low 100's. Moisture return has begun with southeasterly winds over west-central to southwest Oklahoma and western north Texas, which will yield heat index values of 105 to 110 degrees over portions of western Oklahoma and western north Texas. A Heat Advisory remains in effect for these areas until 8 PM.

Dynamic lift ahead of another shortwave may provide sufficient lift to overcome CIN ahead of the dryline and may yield widely scattered thunderstorms this afternoon and evening over northwest/western Oklahoma and western north Texas. A few strong to severe storms are possible with mainly gusty winds and small hail.

Storm chances expand over northern Oklahoma tonight to account for shower/storms moving in from western Kansas and low-level WAA ahead of the aforementioned wave. This activity is not anticipated to be severe.

SHORT TERM

(Friday through Saturday night) Issued at 1030 AM CDT Thu Jul 23 2026

Showers, and perhaps a few thunderstorms, are possible over the northern half of Oklahoma on Friday morning. Activity could linger over east-central portions of the area through early afternoon. While

Dewpoint temperatures are forecast to be higher tomorrow compared to today, and while air temperatures will be roughly the same as today, it will feel hotter. Widespread heat index values of 105 to 110 degrees are expected across the forecast area. A Heat Advisory has been issued for Friday. There is a chance for strong to severe thunderstorms over northwest Oklahoma on Friday afternoon with mainly gusty winds as the main hazard. Low chances shift towards the I-44 corridor on Friday night.

Hot and humid conditions continue on Saturday with widespread heat index values up to 110 degrees possible.

LONG TERM

(Sunday through Wednesday) Issued at 132 AM CDT Thu Jul 23 2026

Ridging is forecast to expand over the southern Plains Sunday into the middle of next week, keeping hot temperatures and mainly dry conditions in the forecast for the foreseeable future.
