KEY MESSAGES

- An Extreme Heat Warning remains in effect through Sunday. The extreme heat will continue into Monday over the west with areas of central Missouri into the eastern Ozarks seeing some modification.

- Hot and dry conditions are worsening drought and increasing fire danger. There is a low chance (20% or less) for scattered showers and thunderstorms both this afternoon/evening and again Sunday afternoon/evening. However many locations will remain dry.

SHORT TERM /THROUGH TONIGHT/

Issued at 206 PM CDT Sat Sep 5 2026

Extreme heat to remain the concern this weekend as the center of a 593dm upper ridge is centered over KS into OK remains the dominant weather feature. A short wave riding the top of the ridge will push a backdoor front moving northeast to southwest into the region Sunday providing a bit of relief to some but not all. Confidence is highest that heat indices on Sunday will again top 105 over southeast KS into western and far southwest Missouri. As the advance and influence of the boundary is better determined, there will be a likelihood that the Extreme Heat Warning will need to be extended.

The 12z SGF RAOB depicted a bit more moisture...with early afternoon cumulus reflecting this increase. The HRRR has maintained the development of isolated to widely scattered showers between 3 and 6 PM...mainly to the south of I-44 today...and there is similar expectations on Sunday. Due to skinny CAPE/poor lapse rates and the amount of dry air that will be quickly entrained...any storms that are realized will be limited and short lived. Severe weather is not expected.

LONG TERM /SUNDAY THROUGH FRIDAY/

Issued at 206 PM CDT Sat Sep 5 2026

Any degree of relief will be short lived Sunday and Monday as the upper ridge rebounds with heights likely climbing to 596dm Monday into Tuesday and 850 mb temperatures warming to around 25 degrees. This will lead to temperatures and heat indices to once again climb back to near or around triple digits CWA-wide Tuesday.

A more significant shortwave moving along the Canadian border will flatten the ridge Wednesday with a frontal boundary expected to descend into Missouri. Better rain chances will be over central Missouri with decreasing coverage farther south. Amounts are expected to be limited to a tenth to a quarter inch.

Falling heights will lead to moderating temperatures following the front into next weekend.

AVIATION /18Z TAFS THROUGH 18Z SUNDAY/

Issued at 1230 PM CDT Sat Sep 5 2026

Moderate cumulus with bases around 6000ft will develop into isolated showers and possibly a few thunderstorms during the mid to late afternoon...otherwise VFR conditions to remain into Sunday.
