KEY MESSAGES

Updated at 145 PM CDT Sun Aug 30 2026

- Hot and dry conditions persist.

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

NEAR TERM

(Rest of today and tonight) Issued at 145 PM CDT Sun Aug 30 2026

Another day with above-average warmth is underway as a ~594 dam subtropical ridge remains centered across the region. Similar to yesterday, hottest conditions (~103 to 107 deg F) are expected across northern portions of Oklahoma, on the periphery of a pronounced low-level thermal ridge and in a corridor of locally drier air. A Heat Advisory continues until 7 PM this evening here. A few locales across the Red River Valley may also reach or exceed the heat headline threshold (105 deg F), though spatiotemporal character is expected to be limited enough to avoid issuance of such products.

Fire weather also remains on the forefront of the forecast this afternoon and evening. The day-over-day combination of hot, dry and windy conditions, amidst critically dry fire fuels, will continue to promote elevated fire weather conditions. A Rangeland Fire Danger (RFD) Statement remains in effect until 7 PM for the area generally west of the I-44 corridor.

SHORT TERM

(Monday through Tuesday night) Issued at 145 PM CDT Sun Aug 30 2026

It will be more of the same as we begin a new work week, with continued above-normal warmth and afternoon/evening fire danger. While the axis of the subtropical ridge looks to migrate eastward a bit during this time, it will remain the primary influence of sensible conditions. Widespread triple-digit heat will persist, with warmest readings expected in agricultural zones of northern Oklahoma and near the Red River. Monday looks to have the lowest heat risk this week, with an influx of greater surface moisture contributing to more widespread >105 deg F heat indices by Tuesday and beyond.

While pressure-gradient-driven winds don't look to be quite as strong on Monday and Tuesday afternoon, some degree of fire weather concern will continue until it rains again. Speaking of, nil chances for precipitation are forecast until no earlier than the late week period.

LONG TERM

(Wednesday through Saturday) Issued at 215 AM CDT Sun Aug 30 2026

The hot and dry conditions will continue through at least the end of the week with deterministic and ensemble NWP in agreement the subtropical ridge will continue to be the primary influence of our weather. High temperatures will continue to range from the upper 90s to the mid 100s deg F. With the ongoing drought and dry fuels, fire weather will also continue to be a concern.

Ensemble spread does begin to increase by the Labor Day weekend with some members indicating the ridge may retrograde to the west to allow a backdoor cold front to be in close proximity with less hot weather. For example, the probabilistic National Blend of Models (NBM) forecast has around an 8 to 15 deg F spread between the 10th and 90th percentile temperatures on Labor Day. The 10th percentile temperature forecast is in the upper 80s (north) to upper 90s (south) deg F. However, the more likely scenario as of now is that the heat wave will continue.
