An unsettled Sunday, with showers and thunder at times; Labor Day brightest to the north

Some Minnesotans woke up to thunder this Sunday morning.

Periods of showers and thunderstorms will continue in many parts of Minnesota into late morning or early afternoon, but the rain is expected to be confined mainly to the southeastern corner of Minnesota by mid-afternoon.

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

We can’t rule out a few strong thunderstorms in Minnesota today, but most thunderstorms are expected to be non-severe.

The Storm Prediction Center of the National Weather Service shows the marginal risk of severe weather just clipping far southeastern Minnesota this Sunday and Sunday night:

Marginal risk means that an isolated severe thunderstorm is possible.

Labor Day

Labor Day should be dry in about the northern half of Minnesota.

There will be a chance of scattered showers and thunderstorms in roughly the southern half of Minnesota on Monday. Far southern Minnesota will see the rain chance first on Monday, then it spreads northward.

The shower/thunderstorm chance in the Twin Cities metro area tomorrow will be mainly mid-to-late afternoon and into the evening.

The National Oceanic and Atmospheric Administration’s North American Mesoscale forecast model shows the potential rain pattern Monday through Monday evening:

Labor Day highs will also be mainly in the 70s, with some upper 60s near Lake Superior:

Twin Cities highs are projected to reach the upper 70s Tuesday, followed by lower 70s Wednesday and Thursday, then mid 70s on Friday.
