KEY MESSAGES

Updated at 610 AM CDT Wed Aug 5 2026

- Low shower and storm chances late Tuesday through Thursday, mostly across portions of northern Oklahoma.

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

NEAR TERM

(Through Wednesday) Issued at 143 AM CDT Wed Aug 5 2026

Today's main story will be the heat with some very low rain chances across northern Oklahoma.

Moisture return will start to push some of our heat indices above 105. We've expanded the heat advisory into more of south central Oklahoma where higher dewpoints are more likely. Parts of central and north central Oklahoma will approach advisory criteria as well (advisory has been expanded some in these areas too), but the potential for cloud cover translates to lower confidence.

A cold front stalled across the OK / KS border will result in some very low (10%) potential for showers and storms in the vicinity this afternoon and evening. Main impact will be the potential for downburst winds. Little to no rainfall is expected.

Day

SHORT TERM

(Wednesday night through Friday night) Issued at 143 AM CDT Wed Aug 5 2026

Latest models have trended downward with PoPs Thursday / Friday as the upper level shortwave appears displaced a bit farther north, with most of northern Oklahoma now confined to 30-40% chance of rain. Highest chances are Thursday evening into the overnight. There is a marginal risk for severe storms with downburst winds.

Moisture return will continue to push up heat indices on Thursday and Friday, resulting in 105+ heat indices across a broader area. Uncertainty will continue to be highest across northern Oklahoma in the vicinity of the front due to potential cloud cover.

Day

LONG TERM

(Saturday through Tuesday) Issued at 143 AM CDT Wed Aug 5 2026

Hot and dry weather will mark this weekend into early next week as the upper ridge tries to reassert dominance over our region. As the front washes out, we should see dewpoints start to mix out again allowing for slightly lower heat indices early next week.

Day

AVIATION

(12Z TAFS) Issued at 610 AM CDT Wed Aug 5 2026

VFR conditions are expected to continue, with a low chance of sprinkles or showers near KPNC and KSWO this morning. Much of any rain falling at the moment is likely evaporating before reaching the surface. The frontal boundary currently draped over northern Oklahoma is anticipated to lift northward with SSW winds expected today. This boundary could sag back into northern Oklahoma by late evening.
