SHORT TERM /THROUGH MONDAY NIGHT/

Issued at 219 AM CDT Sat Apr 4 2026

The cold front that brought showers and thunderstorms to the area last night has slid east of the area. In it's wake CAA has filtered into the region under upper level troughing. This will provide a cool day with highs in the 50s. Tonight, a surface ridge of high pressure will begin to build into the area providing for clear skies and light winds. This decent radiational cooling setup will allow temperatures to drop into the upper 20s to mid 30s. A light freeze will be likely for most of the forecast area north of the Missouri River. The surface ridge of high pressure will build directly over the forecast area on Sunday. This will provide sunny skies but weak mixing which will hold highs in the upper 50s to lower 60s. Sunday into Sunday night, a upper level trough will dig from the Canadian Plains into the Great Lakes. This will force a backdoor cold front through the area Sunday night into Monday. While this frontal passage will be dry it will bring another shot of cooler temperatures. Highs on Monday will only reach the upper 40s to lower 50s north to the low to mid 60s south where cooler air will advect in later in the day. Monday night, temperatures will fall back into the upper 20s to mid 30s with a freeze again possible for areas north of the Missouri River. In addition, weak convergence along a 850mb front may provide the chance (30-60%) of snow showers on Monday night with light accumulation less than half an inch not out of the question for areas of northern Missouri.

LONG TERM /TUESDAY THROUGH FRIDAY/

Issued at 219 AM CDT Sat Apr 4 2026

The extended time frame looks to have the potential to be active as the area will reside under quasi-zonal flow aloft Tuesday through Thursday. Several weak shortwave will provide the chance for showers (20-40%) through the period with better chances across the northern CWA near a stationary frontal boundary which may be the focus for showers. Thursday night into Friday the upper level pattern chances in response to a upper level trough that moves into the California coast and digs into the southwestern CONUS. This will allow an attendant cold front to develop over the Plains States by Friday. Several lead shortwave ejecting out from the upper level trough over the southwest CONUS will move into he region on southwesterly flow aloft. This will provide shower and thunderstorm chances as we get into Friday and Friday night. On saturday the upper level trough ejects out into the eastern Rockies forcing the aforementioned cold front into the area bringing the greatest chance for showers and thunderstorms. Tuesday will be the coolest day through this period with highs ranging from the upper 40s to lower 60s. However, by Wednesday through Friday highs will generally range in the mid 60s to mid 70s.
