KEY MESSAGES

Updated at 129 AM CDT Tue Sep 1 2026

- Hot and dry conditions to continue.

- Fire weather will continue to be a concern with the ongoing drought and dry fuels.

NEAR TERM

(Through Tuesday) Issued at 129 AM CDT Tue Sep 1 2026

Center of the ~596 dam upper high will be centered near the Ohio River Valley today. With the high not being center over the region, we will not see some of the hottest temperatures of the year but temperatures are still expected to be well-above average with highs ranging from 98F to 103F. Triple digit heat indices are also expected across much of the fa this afternoon with heat index values around 105F possible in SE parts of the fa where better moisture/more humid conditions are expected.

Overall, moisture will be a bit better today compared to the last few days with RH dropping to the 20-35% range across the fa. With the slightly higher humidity, elevated fire conditions are not expected this afternoon in terms of weather conditions. However, with the very dry, drought-stricken vegetation, the fuels are still susceptible to wildfires.

SHORT TERM

(Tuesday night through Thursday night) Issued at 129 AM CDT Tue Sep 1 2026

The upper high remains centered east of the region Wednesday and Thursday. Meanwhile, tropical storm Edouard, currently off the coast of Louisiana, is forecast to make landfall Tuesday evening. Models show this system then moving N or NW across eastern TX. Unfortunately, models also show the remnants weakening/dissipating before it can move into/near the fa. However, there is still enough uncertainty that if this system does make it closer or into the fa, some scattered showers/storms might occur in parts of the fa with southeast portions having the best chance late Wednesday night/Thursday.

Moisture will continue to gradually increase keeping minimum RH above 20% across the area. These RHs along with winds not being too strong will keep weather conditions too low to meet elevated fire weather conditions. However, the very dry vegetation will still remain susceptible to wildfires.

Temperatures will continue to be hot, well-above average Wednesday and Thursday with highs in the upper 90s to triple digits. With the increasing humidity, heat indices will continue to climb which will likely lead to a need for heat advisories both days across parts of the fa. There is a chance for temperatures to be a few degrees "cooler" Thursday due to cloud cover associated with the remnants of Edouard but with the uncertainty on the reach of the tropical storm remnants the full impact of any cloud cover on the temperatures is uncertain.

LONG TERM

(Friday through Monday) Issued at 129 AM CDT Tue Sep 1 2026

Models show the upper high shifting west back over the region late this week into early next week leading to hot, humid, and dry conditions.

Highs continue to be in the upper 90s/triple digits through the weekend into early next week. The hot and humid conditions will also continue to lead to triple digit heat indices each afternoon with 105+ heat index values possible in at least parts of the fa.

In terms of the weather parameters, fire weather conditions are expected to remain low the rest of the week into early next week. However, with the very dry vegetation, the fuels will continue to be susceptible to fire. This will likely continue until the fa receives rainfall.

AVIATION

(06Z TAFS) Issued at 1038 PM CDT Mon Aug 31 2026

VFR conditions will prevail through the period. South/southeast winds will veer slightly and become gustier from mid morning Tuesday through the late afternoon period before gusts subside around sunset. Widely scattered showers are possible during the afternoon across southern/southeastern OK, but chances are much too low to include in the TAF at this time (<10%).
