DISCUSSION
Issued at 126 PM CST Sun Mar 1 2026
Tuesday through Thursday
A low pressure system will move slowly east northeast from the Mid Mississippi River Valley east northeast into the southern Great Lakes from Tuesday through Thursday. Warm air advection will initially provide a chance of light rain for the entire area on Tuesday and mainly south of Interstate 90 from Tuesday night into Thursday. The soundings suggest that there might be a chance for some light freezing rain on Tuesday night in central and southwest Wisconsin. This will be highly dependent upon how fast the low levels are able to saturate and how warm are the surface temperatures. Since there is plenty of uncertainty on whether this will even occur, opted to just keep it all rain at this time. Depending on the location of the warm front on Wednesday, there might be a chance for a few elevated storms in northeast Iowa and southwest Wisconsin.
High temperatures will be in the 40s on Tuesday and Wednesday, and range from the mid-40s to mid-50s on Thursday. Low temperatures will gradually warm. They will range from the mid-20 to lower 30s on Tuesday night, in the 30s on Wednesday night, and from the mid-30s to lower 40s on Thursday night.
Friday into Saturday
The flow aloft will become southwest. At the same time, a shortwave trough will eject northeast through the region. This system might bring with it up to 500 J/kg of most-unstable CAPES south of Interstate 94. If this does indeed occur, there could be some scattered storms on Friday night.
High temperatures will range from the lower 50s to lower 60s on Friday and be in the 50s on Saturday. Low temperatures on Friday night will be around 30.
