KEY MESSAGES

Updated at 201 AM CDT Sun Jul 26 2026

- Excessive heat is expected to persist through most of next week. Time outdoors should be limited with plenty of lengthy breaks and hydration.

NEAR TERM

(Through Sunday) Issued at 201 AM CDT Sun Jul 26 2026

Another rinse and repeat day today with the 598dam ridge over the 100th Meridian bringing warm subsidence to the forecast area. Surface troughing will bring some low end breezy south winds. Daytime dry air mixing will scour some of these 70s dewpoints through the day today with slightly lower dews in the 60s. Regardless, it will still feel hot and humid outside. Widespread temperatures ranging from around 100 to 110 degrees with nearly widespread heat indices of 105 to 110 degrees. A few localized hot spot areas may rise above 110 degree heat indices. A Heat Advisory will be in effect for the entire area, except Knox County, today from 11 AM to 9 PM. Cloud cover will be little today with no relief from the sun in this heat and zero chances for precipitation.

SHORT TERM

(Sunday night through Tuesday night) Issued at 201 AM CDT Sun Jul 26 2026

Very hot temperatures will continue into early next week with continued widespread triple digit temperatures. Drier air will fill in across the western portions of the area with slightly less humid heat. However, with temperatures being so warm, heat headlines are still likely to persist each day. With the drier air out west, relative humidity values will drop into the teens and thanks to continued heat and a lack of substantial rain, elevated fire weather may return in the afternoon across portions of western Oklahoma Monday and Tuesday afternoon. Precipitation chances will remain low Monday and Tuesday. Northwesterly flow may return Tuesday and an embedded shortwave could bring low chances for convection off the higher terrain to move into northern Oklahoma late in the evening and overnight hours.

LONG TERM

(Wednesday through Saturday) Issued at 201 AM CDT Sun Jul 26 2026

The upper ridge will continue to expand westward through the latter half of the upcoming week with the heat dome continuing to provide widespread triple digit heat. Several shortwaves will pass to the north of the ridge and being on the eastern periphery, northwesterly flow in combination with the shortwaves may bring chances for precipitation to portions of northern Oklahoma. By Friday, the upper ridge will continue to retrograde westward into the Desert Southwest with a stronger shortwave diving southward across the Central Plains bringing a front through the forecast area Friday. Sadly this front will only bring little relief to the temperatures with triple digit heat still possible.

AVIATION

(06Z TAFS) Issued at 1052 PM CDT Sat Jul 25 2026
