A strong storm system moving into the Upper Midwest may produce a few severe thunderstorms this afternoon and evening. There is a slight risk (level 2 on a scale of 1 to 5) from western Wisconsin to northeastern Iowa. A marginal risk extends down the Mississippi River into Iowa and Missouri.
Tornadoes, large hail and damaging wind gusts are possible. The window for severe development is narrow, near peak instability in the later afternoon and early evening. As the low moves from eastern Minnesota into northern Wisconsin, a cold front will move eastward. Areas along the front have the potential to see severe storms.
In the much colder air northwest of the low, heavy snow is possible. Stay tuned to WeatherNation on-air and online for the latest updates.
