KEY MESSAGES

Updated at 1225 PM CDT Tue Aug 11 2026

- Oppressively hot and dry weather will persist through the work week and into the upcoming weekend.

- Rain chances are unlikely through the forecast period.

SHORT TERM

(Through tonight) Issued at 1151 AM CDT Tue Aug 11 2026

If you remember what it felt like yesterday, you have a good idea of what to expect for the rest of today and tonight, with a near carbon copy likely. 24-hour temperature and dew point trends are running within a degree or two of yesterdays values, which supports widespread heat index values this afternoon in the 105 to 110 range. One change that will be made today is expanding the Heat Advisory to all of eastern Oklahoma and northwest Arkansas, as well as extending it in time through Friday afternoon. These changes were made due to the prolonged nature of the afternoon heat, as well as winds and dew points keeping overnight temperatures up in much of the forecast area as well. Speaking of, lows tonight will again be in the mid and upper 70s in much of the area with local values - looking at you, Tulsa - in the lower 80s.

LONG TERM

(Tomorrow through Tuesday) Issued at 1151 AM CDT Tue Aug 11 2026

For the remainder of the work week, near persistent daily conditions will be in the offing, with upper level high pressure solidly in control of the weather across the area through at least the weekend and likely into next week as well. Low level temperatures support continued widespread triple digit ambient temperatures across the region, with heat index values mainly in the 105 to 110 range. Overnight low temperatures are also expected to remain similar, providing little relief from the afternoon heat. The aforementioned extension of the Heat Advisory through the day Friday was a fairly conservative one, and the expectation is that this will need to eventually be extended through at least the weekend. Uncertainty increases slightly for the early part of next week, with the high pressure center shifting westward and potential for a disturbance and weak cool front to affect mainly northern portions of the region. The bulk of the impacts from this still look to remain north of the area but these features may bring a modest uptick in the rain chances for a lucky few.

AVIATION

(18Z TAFS) Issued at 1225 PM CDT Tue Aug 11 2026
