Rain chances
Scattered showers are possible in Minnesota and western Wisconsin this Sunday and Sunday evening. The rain showers aren’t expected to last very long in any one spot. Far northern Minnesota could see some large areas of showers Sunday afternoon and evening, with an isolated thunderstorm also possible. As always, updated weather information can be heard on the Minnesota Public Radio Network, and you’ll also see updated weather info on the MPR News live weather blog.
Scattered showers and thunderstorms could move into northern and west-central Minnesota Monday afternoon. Showers and t-storms will probably expand in coverage to include the rest of Minnesota plus western Wis. as we go through Monday evening and Monday night. In the Twin Cities metro area, our shower/t-storm chance on Monday will probably hold off until Monday evening.
The National Weather Service Storm Prediction Center shows a slight risk of severe weather Monday and Monday night for much of Minnesota and western Wisconsin. Slight risk means that scattered severe thunderstorms are possible. Our Twin Cities metro area risk of severe weather would tend to be Monday evening or overnight Monday night. Here’s a look at the risk area and the timing of the severe risk, from the Twin Cities NWS office:
