KEY MESSAGES

Updated at 616 PM CDT Wed Jul 29 2026

- Very hot conditions continue through Friday with less hot conditions for the upcoming weekend.

- There is a low chance of showers and thunderstorms Thursday night into Friday with a front.

NEAR TERM

(Rest of today and tonight) Issued at 126 PM CDT Wed Jul 29 2026

Another day of heat being the main story. Temperatures are expected to climb into the triple digits this afternoon across much of the fa. The exception may be parts of northern OK depending on how long an outflow boundary and some cloud cover is able to influence the area. Even hotter heat indices are expected this afternoon, especially in far east or southeast parts of the fa where moisture is the highest and heat index values of 110+ are possible. Will continue with the current heat advisory and extreme heat warning for this afternoon.

There have been some scattered sprinkles/light rain showers that have moved across parts of northern OK this morning. Showers and maybe a few storms will remain possible (15-20%) in northern OK through the afternoon with the area expected to gradually shifting into north central OK.

Another warm night tonight with lows in the mid/upper 70s. Additional elevated showers may develop late tonight/early Thursday in parts of southern KS into northern OK.

SHORT TERM

(Thursday through Friday night) Issued at 126 PM CDT Wed Jul 29 2026

Another hot day Thursday with the upper high dominating the region. High temperatures are expected to climb into the triple digits across much of the area again tomorrow with 105+ heat indices. A few locations could see heat indices of 110+ tomorrow afternoon. Have issued a heat advisory for the entire area for Thursday afternoon but later shifts may need to issue a extreme heat warning for a few areas if it looks likely that the 110+ heat indices will occur.

Models show the center of the upper high shifting westward Thursday night into Friday as a shortwave drops SE across the northern Plains into the Midwest with NW flow developing over the area Friday. This will cause a "cool" front to move into the area late Thursday night into Friday (at least in terms of the wind shift). It looks like the "cooler" air will lag a bit which means overall Friday will be another hot day with highs in the upper 90s to around 100 in northern OK to 103-106 F range in the Red River area. Heat indices will also be high once again with a heat advisory and maybe an extreme heat warning needed again on Friday. There is some uncertainty on where but most likely area will be at least parts of southern OK and western north TX.

In terms of rain, showers and thunderstorms will be possible late Thursday night into Friday night with chances shifting southward with the boundary. With the main synoptic forcing further N and NE, chances are not high (mainly 20-30%) but at least there is a chance.

LONG TERM

(Saturday through Tuesday) Issued at 255 AM CDT Wed Jul 29 2026

Cooler/less hot weather arrives on Saturday with more appreciable cold air advection in the wake of the cold front. However, the strongest cold air advection will remain to our northeast across the Great Lakes and Midwest. As a result, the most significant cool down will be across north central Oklahoma. High temperatures are forecast to range from the near 90 deg F (north central Oklahoma) to near 100 deg F (southwest Oklahoma and western north Texas). In other words, this cold front will bring us closer to normal for early August.

Near normal temperatures will continue into Sunday before a slow warming trend begins on Monday with a strengthening ridge aloft and attendant thermal ridge expanding eastward--back toward the Southern Plains.

AVIATION

(00Z TAFS) Issued at 616 PM CDT Wed Jul 29 2026

VFR conditions to continue.

Light southeast winds expected overnight with some mid and highs clouds. Winds will veer to the southwest in the morning and then back to the south during the afternoon. There will be some high- based cu tomorrow afternoon and an outside chance of a shower, but chances remain too low to mention in TAFs at this time.
