Discussion

(this afternoon through next tuesday) issued at 1113 AM CDT wed sep 16 2026

Hot conditions will continue underneath a 600 dam ridge with afternoon highs reaching the upper 90S to low 100S. Starting thursday, the ridge will begin to slowly retrograde west as a tropical wave approaches florida. Despite the westerly movement, near record to record highs are forecast through the weekend. The heat advisory has been extended through 8 PM saturday for the entire forecast area. Given the prolonged nature of this heat, vulnerable populations are at the greatest risk for developing heat-related illness. Remember to regularly check on neighbors and ensure ample hydration over the coming days.

Both the GFS and ECMWF depict a shortwave developing to the lee of the rockies on sunday. This feature will send a weak frontal boundary into the mid-south late monday into tuesday. Rain chances will increase, but we are still not anticipating a widespread rainfall event. Temperatures will decrease a few degrees by the middle of next week, but above-average highs are favored through the end of the month.
