Thunderstorms at times today and tonight; a dry Sunday

The atmosphere will be unsettled across Minnesota and western Wisconsin today and tonight.

You can expect some thunderstorms at times, and a severe thunderstorm is possible.

Updated weather information can be heard on the Minnesota Public Radio Network, and updates are also posted on the MPR News live weather blog.

The Storm Prediction Center of the National Weather Service shows a slight risk of severe weather this afternoon and tonight in far southern Minnesota, with a marginal risk of severe weather for much of the remainder of Minnesota, including the Twin Cities metro area:
