Recipe for an early ice-out year in Minnesota

We’re seeing the perfect combination of weather ingredients for early ice out in Minnesota this year.

  • 1 heaping tablespoon warm March

  • Splash of rare March rainfall

  • Mix in strong sunshine to penetrate ice and warm water from below

  • Stir with 3 cups of wind

  • March has been windy. So far 16 days this month have produced wind gusts over 20 mph at Minneapolis-Saint Paul International Airport.

  • March temperatures are running 8.6 degrees warmer than average in the Twin Cities.

  • Overall temperatures across Minnesota are about 10 degrees warmer than average this month. It makes for a sea of warm colors on the March temperature departure map.

Ice out moves north

Our warm, rainy, windy March is starting to dissolve ice further north on some lakes in central Minnesota, too. Many lakes in Otter Tail County near Fergus Falls are now ice-free.

Blanche Lake just south of larger Otter Tail Lake shows ice-out Tuesday, too. That’s also more than two weeks ahead of the average date of April 15.
