KEY MESSAGES

Updated at 129 AM CDT Thu Sep 3 2026

- Very low chances for rain on Thursday across south central Oklahoma but otherwise dry through the forecast.

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

NEAR TERM

(Through Thursday) Issued at 129 AM CDT Thu Sep 3 2026

The upper high will remain over the SE U.S. today. Meanwhile, the remnants of Edouard will also continue to drift as it weakens across parts of eastern TX today. These remnants might bring a chance (15- 20%) of rain to far SE portions of the fa today. However, rainfall amounts will be light (<0.25"), if the area receives any rain at all. Otherwise, most of the fa is going to be dry once again today.

Hot, well-above average temperatures are expected again today with highs ranging from the mid/upper 90s (generally along and east of I- 35) to the low 100s across the rest of the area. The temperatures east of I-35 will be a few degrees "cooler" but still well above average for early September. There is some uncertainty with the temperature forecast today due to expected cloud cover from the effects from the remnants of Edouard, especially in SE parts of the fa. If clouds are more extensive and/or hang on longer than expected, then the temperature forecast may be too hot. On the reverse side of that if there is not as much cloud cover then temperatures could be hotter than currently forecast.

Moisture is also expected to continue to gradually increase today leading to more humid conditions, especially across eastern portions of the fa. The hot and humid conditions will lead to heat index values in the 105 to 110F range this afternoon and early evening across parts of the area. A heat advisory is in effect from 1 PM to 7 PM with some adjustments made. Removed the advisory for south central OK where cloud cover is expected to keep temperatures down just enough. Also expanded the advisory to include the rest of western north TX and added some counties in central and north central OK.

SHORT TERM

(Thursday night through Saturday night) Issued at 129 AM CDT Thu Sep 3 2026

The upper ridge begins to build back into the central U.S. Friday and Saturday with the ridge axis centered more over the central/southern Plains. With the ridge over the region, the hot, humid, and dry conditions will continue across the fa with no chance for rain.

High temperatures of upper 90s/low 100s will return areawide for the end of the week. Heat indices of 105-110F are also expected to become more widespread Friday and Saturday with the potential for some values of 110+ possible in SE parts of the fa. Heat advisories at least will very likely continue into Friday and Saturday with the potential for an extreme heat warning in some areas.

With the humid conditions sticking around, fire weather conditions will remain low but the drought-stricken vegetation will remain susceptible to wildfires across the area Friday and Saturday.

LONG TERM

(Sunday through Wednesday) Issued at 129 AM CDT Thu Sep 3 2026

The upper ridge will continue to influence the region into next week which will cause the hot and humid conditions to persist with highs in the upper 90s and low 100s along with heat index values in the 105-110F range. These conditions mean that heat headlines (most likely heat advisories) will continue into at least early next week.

Unfortunately with the ridge over the area, it looks like there will not be much of a chance for any much need rainfall into next week as well. Fire weather conditions will also remain low but as mentioned earlier the very dry vegetation will remain susceptible to wildfires so everyone needs to take steps to prevent fire starts.

AVIATION

(06Z TAFS) Issued at 1023 PM CDT Wed Sep 2 2026

VFR conditions expected across much of the area through the forecast period. However, MVFR ceilings are expected to develop across southeast Oklahoma later tonight as lower level moisture surges northward ahead of remnants of tropical storm Edouard. DUA will likely see these lower ceilings through the morning into the early afternoon before rising back to VFR. These lower ceilings could also approach OKC/OUN after sunrise so will maintain a TEMPO for a couple of hours for this potential. Otherwise, similar conditions to today with some afternoon hihg-based cu and breezy south to southeast winds.
