DISCUSSION
Issued at 148 AM CDT Sat Jun 20 2026
Skies have cleared following yesterday's severe thunderstorms. Some diurnal CU will develop late morning and some weak SBCAPE could materialize across northern WI in the afternoon. Can't rule out some low-topped showers or weak thunderstorms northeast of Rice Lake and Eau Claire during peak heating, so maintained the 20 PoPs. The next system to watch will emerge over the central Plains today. A warm front and rich moisture will be in place across NE/KS/northern MO which will spark heavy rain producing clusters of thunderstorms through tonight. Much of this activity will remain well to the south, but enough moisture may advect north into far southern MN and eastern SD to support a few showers Sunday.
A system traversing east along the U.S./Canadian border Monday will bring some increasing moisture northward by Tuesday, although it won't be particularly impressive. A cold front will pass through during the afternoon likely bringing a round of showers. Very poor mid level lapse rates and drier air in the boundary layer will lead to little CAPE and a meager thunder threat. The low will sink southeast along the Mississippi River to southern Wisconsin Wednesday. Wrap around showers and perhaps a thunderstorm may continue into Wednesday evening. Troughing with cool temperatures aloft and pwats remaining around an inch and a quarter could bring a few diurnal showers through the rest of the work week. The trough will also keep surface temperatures below average.
By next weekend, there are signs of ridging trying to build back to the Upper Midwest with a potentially more active pattern developing, along with temperatures returning closer to normal.
