KEY MESSAGES

Issued at 1207 AM CDT Wed Aug 26 2026

- The oppressive heat resumes today for much of our Four-State area with more triple digits, but with better rain chances. - A weak cool front will soon be nudging the upper ridge farther west, with scattered showers and thunderstorms for mid to late week, some could be severe late today and into the overnight.

- Mostly sunny skies return this weekend with little to no rain as the upper ridge expands back over the MidSouth. Next week we may see the sea breeze lift into our area mid to late days.

DISCUSSION

Issued at 106 PM CDT Tue Aug 25 2026

Once again a nice area of mid and high clouds kept the heat at bay, just not as much winds from the east. However, today we will resume with SW winds today and afternoon sunshine. Our high temperatures will respond quickly back into the triple digit range, as our soil deep down remains warm and dry in the lower 80s for the early the midnight observation. Currently we see light SE winds with a wide range of air temperatures still around 80 degrees for most sites. The upper ridge is currently parked over New Mexico with some convection for the panhandles and middle Red River valley in progress and a good outflow headed over Lake Texoma around daybreak. This surface forcing may trigger some light showers north of I-30 early with better rain chances arriving well ahead of an approaching cool front.

The moisture will be pooling ahead of the front and mid to late day heating will boost the heat index, but also help to develop convection for us. The SPC has a Marginal Risk in place for today and tonight with a damaging wind potential. The WPC has outlooked our area for excessive rainfall, due to slow movement of activity. We can expect the surface winds to vary around convection and perhaps become gusty in the heat. The prevailing winds will slack and vary with N/NE winds arriving early on Thursday down to near I-20. The cool front will take a day or two to push down and out of our area, but should do so during Friday, taking the needed rain chances along with down to I-10.

Our high temps will get back to average for late August with little to no rain expected this weekend. The upper ridge will retrograde a bit into Arizona, keeping a foot hold on New Mexico by late Thursday. All due to the short wave energy piling in under a deep low over Hudson Bay, which will be spreading across the middle MS River Valley nudging the surface front, along with a convective assist, a little farther south for our nice summer weekend. However early next week, the upper ridge expands back over Missouri and Arkansas with more heat headlines likely for us as we put a bow on August. The GFS/ECMWF long range picture both develop a weakness aloft over the NW Gulf, which may help the sea breeze to make gains inland each late day early through midweek.

AVIATION

(12Z TAFS) Issued at 541 AM CDT Wed Aug 26 2026

Widely scattered showers currently going on across the western and northwestern half of our airspace attm. This activity has shown a slow tendency to advance south and east and may expand a little more in coverage before dissipating later this morning. Otherwise, we await upper forcing tied to a potent shortwave that will move from northwest to southeast across our region overnight tonight. Along and in advance of this feature, we should see scattered convection once again late this afternoon, evening and overnight across our region. Have therefore inserted VCSH and/or VCTS and began this as early as 21z across our northern most terminals and closer to 00z most other terminals.
