There is a moderate risk of severe weather on Monday – a Category 4 out of 5 – from the Twin Cities to the west. This severity occurs only about twice a year in the state and only about once a year in the metro.

⚠️ RARE HEAVY WEATHER SETUP in #MNwx #WIwx today means most of us will experience dangerous weather.

The first round of storms will occur early Monday morning, with Minnesota’s storm system moving southwest to northeast. Wind is the main threat from this storm, which could bring gusts in excess of 70 miles per hour.

There should be a lull in storm activity around noon, with the second round arriving around dinner.

This system will be a series of storms flaring up in western Minnesota and moving east. This line has a higher tornado risk than the first round of storms — and those chances are highest in western Minnesota.

That region also has a moderate risk of damaging hail Monday, and most of the state — excluding Arrowhead and far-eastern Minnesota — also has a moderate risk of damaging winds.

The serious threat subsides around 10 p.m. Monday.

Tuesday will be less humid and cooler but still has a chance of storms. We then enjoy a quiet midweek with highs in the 70’s and lows in the 50’s.

More storms are possible next weekend.
