Foggy in many areas; heaviest snow stays north Sunday night into Monday

Our Saturday afternoon high of 38 degrees at Minneapolis-St. Paul International Airport was 13 degrees warmer than average for this time of year. It was also our warmest official high temp in the Twin Cities since Jan. 8.

It was nice to see a lot of people out and about, and not bracing against arctic winds!

Temperature trends

Sunday highs will range from the upper teens in far northwestern Minnesota to lower 40s in the far southeast. The Twin Cities metro area should reach the upper 30s.

On Monday, colder air will spread across much of Minnesota:

The metro area will probably see a Monday morning high temp in the 20s, with slowly falling temps throughout the day.

Tuesday highs will be chilly:

Twin Cities metro area highs are expected to reach the lower 20s on Wednesday, followed by teens Thursday and Friday.

Dense fog

A dense fog advisory continues Saturday evening, overnight Saturday night and Sunday morning from the southern part of The Twin Cities metro area and Pierce county, Wisconsin through south-central and southeastern Minnesota and southwestern Wisconsin:

Wintry mix and snow Sunday evening into Monday

A low pressure system is expected to spread snow into parts of northwestern Minnesota on Sunday. The snow area expands across most of northern Minnesota Sunday evening, with the snow continuing Sunday night into Monday.

Southern Minnesota and the Twin Cities metro area could see a wintry mix of rain, light freezing rain, sleet and snow Sunday night, changing over to all snow at some point on Monday.

The National Oceanic and Atmospheric Administration’s North American Mesoscale forecast model shows the potential precipitation pattern from Sunday through Monday afternoon:

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 snow or rain.

The heaviest snow Sunday evening into Monday is expected to fall in northwestern Minnesota and parts of north-central and west-central Minnesota.

A winter storm watch runs from 6 p.m. Sunday to 6 p.m. Monday for much of that area, it is for a wintry mix followed by a possible three to six inches of snow plus blowing snow:

NWS Grand Forks

The watch begins at noon Sunday in Minnesota counties along the Red River.

You can check the NWS Grand Forks site for updates on the winter storm watch.

Snow depth

If you’re planning to play in the snow on Sunday, you’ll be interested in the latest Minnesota snow depth map from the Minnesota State Climatology Office:
