A severe thunderstorm watch continues until 9 p.m. this Saturday for portions of southern Minnesota:

The severe thunderstorm watch does not include the Twin Cities metro area.  Southern portions of the metro area could see scattered showers/thunderstorms late Saturday afternoon, and the entire metro area will have a chance of scattered showers and thunderstorms Saturday evening, with an isolated severe storm possible.

Details of the severe t-storm watch for portions of southern Minnesota, from the Storm Prediction Center of the National Weather Service:

Simulated radar

The National Oceanic and Atmospheric Administration’s High Resolution Rapid Refresh (HRRR) model shows the potential rain pattern Saturday afternoon through Saturday night:

The color chart to the right of the loop refers to the strength of the signal that returns to the radar, not to the amount of rain. It'll rain in some areas that look dry in the HRRR loop, but the loop shows the general rain pattern within the model. We could see scattered morning showers in Minnesota and western Wisconsin on Sunday.

You can see the recent local images from the local NWS radar here.   The recent radar loop for southwestern Minnesota can be found here. The southeastern Minnesota radar loop can be found here.

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.
