KEY MESSAGES

Issued at 237 PM CDT Fri Sep 4 2026

- Above normal summer heat returns through the weekend into early next week (upper 90s likely). Chances for hazardous heat remain elevated through this time period as a result.

- Daily chances of afternoon showers and thunderstorms will persist through this weekend into most of next week.

DISCUSSION

Issued at 237 PM CDT Fri Sep 4 2026

Ridging continues to build and shift northwestward into the Southern Great Plains the weekend begins. This ridge axis (and its evolution) mostly to our north will serve as the primary influence on weather conditions through the weekend and next week into mid-September. Zonal flow underneath this ridge will continue to steer disturbances westward, and combined with lower geopotential heights/weaker atmospheric subsidence, convective rounds will develop inheriting this westward propagation. With dew points remaining in the low 70s through the weekend, the potential for heat hazard product issuance also remains elevated (especially along and north of the I-30 corridor into south Arkansas. Medium- range guidance suggests a window of Sunday through Tuesday for our greatest chances (25 to 50 percent) of temperatures reaching or exceeding 100 degrees, especially north of the I-20 corridor where air remains more subsident. Long-range guidance suggests more of the same as somewhat westerly zonal flow aloft funnels more perturbations (instigating convection) in our direction. That said, the convection that does develop will most likely be in the form of a diurnal pattern with the best chance of rain south of the I-20 corridor under less inhibition from ridging to the north. Resulting WPC QPF Day 1-7 values reflect that distribution with 0.01 to 0.25 inch rainfall totals likely north of I-20 and 0.25-0.75 inch totals likely to the south. /16/
