KEY MESSAGES

Updated at 147 PM CDT Mon Aug 10 2026

- Hot temperatures continue through at least mid week with triple digit heat and at least a moderate heat risk.

- Elevated fire weather across parts of western Oklahoma Monday and Tuesday.

NEAR TERM

(Rest of today and tonight) Issued at 147 PM CDT Mon Aug 10 2026

The forecast remains on track with temperatures and/or heat index values in the triple digits across most of the area. Elevated fire weather conditions this afternoon, but slightly higher humidity and lower wind speeds will keep conditions in the elevated category as opposed to near-critical.

A decent cumulus field has developed in south central Oklahoma, and the FV3 and to some extent the ARW versions of the WRF do develop some convection this afternoon. Have added 10% POPs with the mention of isolated thunderstorms across south central Oklahoma toward the Wichita Falls area for late this afternoon.

SHORT TERM

(Tuesday through Wednesday night) Issued at 147 PM CDT Mon Aug 10 2026

Stop me if you've heard this before, but it's going to be hot again Tuesday. And Wednesday. Temperatures Tuesday are expected to be similar to today, but we may keep slightly higher dewpoints which will allow heat index values to be a degree or two higher tomorrow. And still no organized potential of precipitation... although we can not completely rule out very small chances (less than 20%) of isolated thunderstorms in the afternoon with temperatures approaching the convective temperature in forecast soundings, but the potential is too low to mention in the forecast at this point.

LONG TERM

(Thursday through Sunday) Issued at 1217 AM CDT Mon Aug 10 2026

Hope continues to dwindle for the long term as models trend toward a stronger ridge keeping us mostly hot and dry. We still have some low chances for rain across the north this weekend, but that's about it. Moisture return will help limit fire concerns, while at the same time keeping those heat indices high.

Day

AVIATION

(18Z TAFS) Issued at 1156 AM CDT Mon Aug 10 2026

VFR conditions will once again persist through the period. Southwesterly winds will relax this evening, and back to the southeast overnight. Winds will then veer tomorrow morning towards the southwest, and become gusty through the remainder of the morning.
