KEY MESSAGES

Updated at 553 AM CDT Sat Aug 8 2026

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

- Elevated fire weather across parts of western Oklahoma Saturday through Monday

NEAR TERM

(Through Saturday) Issued at 132 AM CDT Sat Aug 8 2026

Showers and storms brought some much needed relief from the heat yesterday afternoon along the I-35 corridor. Unfortunately, most of our rain chances have come to an end as the ridge builds back in. Today's headlines will feature heat and some elevated fire weather.

Heat indices are forecast to be in the 102 to 108 range under mostly clear skies. WBGT's will be firmly in the high, pushing to extreme category across most of the forecast area.

Parts of western Oklahoma may see elevated RFTIs as RHs dip into the upper teens. Winds will be southerly at 10 to 15 mph. With ERCs near the 95th percentile, we'll be issuing an RFD for these counties.

Finally, the departing shortwave will give us a very low chance for some showers and storms in south central Oklahoma this afternoon.

Day

SHORT TERM

(Saturday night through Monday night) Issued at 132 AM CDT Sat Aug 8 2026

Hot and dry is the forecast for Sunday and Monday with heat indices rising into the 100-107 range.

Elevated fire weather is expected across parts of western Oklahoma on Sunday (lesser chances on Monday) due to RH values falling into the mid to upper teens. Winds will be a bit breezier Sunday and Monday as well, blowing from the south to south southwest at 15-20 mph with gusts to 30 mph (mainly across northwestern Oklahoma).

Day

LONG TERM

(Tuesday through Friday) Issued at 132 AM CDT Sat Aug 8 2026

Summer heat continues through about mid week next week as the upper ridge keeps us dry and mostly sunny.

Synoptic uncertainty increases significantly after Wednesday. There's a signal for one or more systems to move through the central plains mid to late week (bringing rain chances and cooler temperatures, with the highest chances in northern Oklahoma), but ensemble members diverge greatly on timing.

Day

AVIATION

(12Z TAFS) Issued at 553 AM CDT Sat Aug 8 2026

Lingering cloud cover from overnight storms has mostly departed the area, though a few reports of scattered around 10,000 feet are still registering. Given the rain yesterday, would expect at least some fair-weather cumulus development near I-35 during the afternoon hours. Otherwise, VFR conditions should continue with winds around 10 knots this afternoon and tonight.
