KEY MESSAGES

Updated at 603 PM CDT Sat Jul 25 2026

- Excessive heat and mostly dry conditions through end of the week.

NEAR TERM

(Rest of today and tonight) Issued at 205 PM CDT Sat Jul 25 2026

Dangerously hot/humid conditions are present at this hour across the area with air temperature readings near 100 degrees (western half of Oklahoma); heat index values near/above 110 degrees are widespread across northern Oklahoma with 114 deg observed in Alva. Unfortunately, the lightest winds are co-located with the highest heat index values and are resulting in extreme wet-globe temperature risk over northern Oklahoma. Elsewhere, breezy south/southwest are providing at least some relief.

There is a very low chance of a pop-up thunderstorm late afternoon over northwest Oklahoma, if convective temperatures are breached and subsidence overcome.

Temperatures will be slow to fall below the century mark (by 8 PM or so over western OK. Overnight low temperatures will be just under 80 deg and offer little relief for those without air conditioning.

SHORT TERM

(Sunday through Monday night) Issued at 205 PM CDT Sat Jul 25 2026

Dangerous heat and dry conditions continue through at least Monday..

The center of the 598dam ridge is modeled to remain nearly stationary with south/southwesterly winds prevailing under sunny skies. Continued daytime mixing will lead to a downward trend in dewpoint temperatures Sunday and Monday. Drybulb temperatures will thus increase over the next two days. High temperatures of 100 to 105 will be common and the highest values of 110 deg possible in the vicinity of Woods, Alfalfa, Major Counties. A Heat Advisory has been issued for much of the FA for tomorrow. Overnight low temperatures will be similar to those expected tonight - mid- to upper-70s.

LONG TERM

(Tuesday through Friday) Issued at 141 AM CDT Sat Jul 25 2026

The remainder of next week will continue to feature very hot temperatures and the potential for daily Heat Advisories. The upper ridge will center more over New Mexico, which will bring back north northwesterly flow through the week. Afternoon convection along the higher terrain in Colorado could be driven southeast by any embedded shortwaves in the northwest flow aloft into northern Oklahoma during the late evening and overnight hours, but currently the chances remain low. A weak cold front late in the week may bring some relief to the triple digit heat by next weekend.

AVIATION

(00Z TAFS) Issued at 603 PM CDT Sat Jul 25 2026
