KEY MESSAGES

Updated at 1216 PM CDT Sat Mar 21 2026

- Record-breaking heat continues into Sunday.

- Fire weather conditions on Sunday will be the biggest concern, as winds strengthen ahead of and behind a cold front where humidities will be low and fuels abundant.

- Low rain chances late next week with another front.

SHORT TERM

(Through tonight ) Issued at 1216 PM CDT Sat Mar 21 2026

Record or near record heat will continue this afternoon, with temperatures warming into the upper 80s to mid 90s. Persistent south winds overnight will hold overnight lows up in the upper 50s to mid 60s.

LONG TERM

(Tomorrow through Saturday) Issued at 1216 PM CDT Sat Mar 21 2026

Record to near record heat will continue Sunday, just ahead of a cold front that will enter northeast Oklahoma by late morning and push through the area during the afternoon and evening. Gusty south to southwest winds ahead of the front will shift to the north and remain gusty following the frontal passage. The combination of very warm temperatures, low humidity values, and strong and gusty winds will result in near critical fire spread rates across much of eastern Oklahoma and parts of far northwest Arkansas from late Sunday morning through early Sunday evening, and the existing Fire Weather Watch has been upgraded to a Red Flag Warning as a result.

Much cooler, but still above normal, temperatures are expected Monday before a warming trend again raises temperatures to unseasonably warm levels by Wednesday and Thursday of next week. Gusty south winds will also raise fire weather concerns again during this period.

Another cold front is expected at the end of next week, bringing somewhat cooler temperatures and at least low rain chances to some places.
