KEY MESSAGES

Updated at 452 AM CDT Thu Aug 6 2026

- Low shower and storm chances through Friday, mostly across portions of northern Oklahoma. Marginal risk for severe storms this afternoon across northern Oklahoma.

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

NEAR TERM

(Through Thursday) Issued at 139 AM CDT Thu Aug 6 2026

Today's weather pattern will be similar to yesterday's--hot and mostly dry, aside from some low rain chances in the north. The biggest change is that rain chances continue to dwindle for Thursday night with PoPs now in the 20-30% range.

Today's heat index map probably won't look too much different from yesterday's. Expect heat indices in the 100-108 range with the heat pockets likely forming in north central and south central Oklahoma. Potential cloud cover adds some uncertainty to northern Oklahoma, though if yesterday was any indication, I wouldn't expect too much in the way of heat relief. We've expanded the heat advisory based on yesterday's heat indices.

A boundary sits stalled near the OK / KS border. This will be a focus for low shower and thunderstorm chances (10-30%) today and tonight. Models suggest chances for a round early this morning (aided by the low level jet) and a round late this afternoon and evening (aided by diurnal heating). With the afternoon convection, the main impact will be damaging wind gusts, though the environment could support some hail producing supercells as well.

Day

SHORT TERM

(Thursday night through Saturday night) Issued at 139 AM CDT Thu Aug 6 2026

Rain chances peak (at 20-30%) early Friday morning and extend down to the I-40 corridor by early afternoon.

Other than slightly more numerous showers, Friday will look much like previous days with heat indices again rising into the 100-108 degree range. That said, uncertainty with the cloud cover and rain is probably highest on Friday and that could impact temperatures.

Hot and dry again on Saturday (but without the low rain chances or associated cloud cover). Dewpoints may mix out a bit more, keeping heat indices a degree or two lower. Unfortunately, this also means we may see some patchy elevated fire weather across western Oklahoma and western north Texas as well.

Day

LONG TERM

(Sunday through Wednesday) Issued at 139 AM CDT Thu Aug 6 2026

Not much change in the pattern next week as the ridge continues to dominate the forecast. Mostly hot and dry, though there are some hints that rain chances may approach from the north occasionally. Elevated fire weather will also be a concern early in the week across western Oklahoma and western north Texas.

Day

AVIATION

(12Z TAFS) Issued at 452 AM CDT Thu Aug 6 2026

A linear complex of thunderstorms are currently nearing the Kansas border and tracking southeastward. Considerable uncertainty exists on whether these will maintain upon approaching KWWR and KPNC, and therefore, added PROB30's at these terminals this morning. This activity is expected to remain sub-severe with perhaps gusty winds to 25 mph.

Otherwise, VFR ceilings are expected with modestly breezy south winds veering towards the southwest later this morning. Scattered strong to severe thunderstorms are possible by late afternoon and into the evening across northern Oklahoma. Latest high-resolution models suggest storms have a higher chance of forming near KPNC. Storms that develop will have the potential for severe downburst winds up to 70 mph.
