DISCUSSION

Issued at 141 AM CDT Sun Aug 30 2026

The main forecast concern will continue to be the well above normal temperatures which will finish out the weekend and continue through next week. This will come courtesy of an upper level ridge which will be anchored over the area. Today through Tuesday the upper level ridge axis will remain directly over the area. This coupled with moderate WAA over the area through that same period will keep highs 10 to 15 degrees above normal in the mid 90s to near 100. There will be a very gradual increase of dewpoints through this period which will aid in a gradual increase of heat indices through this period as well. Heat index values today will be in the 95-102 range but will rise to 100-105 by Tuesday. The only shot of precipitation through this period will come this morning across far northern Missouri where a slight chance (15-25%) of a light shower/isolated thunderstorm is possible.

Wednesday, the upper level ridge axis begins to slide southeastward however, the local area will remain under its influence keeping highs in the mid 90s to near 100. Wednesday night into Thursday a upper level shortwave will move from the Great Basin region into the northern Plains. This will force a cold front into the Upper Midwest to central Plains. This will increase moisture into the area and this coupled with weak shortwaves rounding the upper level ridge will have the chance (15-25%) to bring a few rounds of storms to the area Thursday and Friday. While there is the chance that showers and cloud cover may limit temperatures a bit, highs Thursday and Friday are still expected to reach the mid to upper 90s. With more ample moisture being ushered into the area in the Wednesday-Friday period, heat index values for most will still remain between 100-105 however, some areas south of the Missouri River may rise into that 105-110 range which may require heat headlines for part of the forecast area. Saturday, models suggest the upper level ridge begins to retrograde back west with the axis building back across the region. This will continue to keep temperatures will above normal in the 90s.
