Monday morning freezing fog, then mild; turned 50 degrees Wednesday


Minnesota and western Wisconsin enjoyed a beautiful December afternoon, which ended with a beautiful sunset.

Sunday’s high temperature in Minneapolis-St. Paul International Airport was 36 degrees, 6 degrees higher than the Dec. 12 average in the Twin Cities. Much of Minnesota and western Wisconsin peaked in the 1930s, with a few places in west-central Minnesota exceeding 40 degrees.

Possible fog / freezing fog

The winds will pick up late Sunday evening. Light winds will allow the temperature to drop to the dew point, with the development of fog. Some areas of fog and freezing fog are possible in Minnesota and western Wisconsin late overnight Sunday through Monday morning. Check for forecast updates.

Some spots in the Twin Cities metropolitan area could reach their 30s on Monday and Tuesday. The metropolitan area will peak in the upper 40s at around 50 on Wednesday. The far south of Minnesota will have many highs Wednesday in the 1950s, and a few places in the far southeast of Minnesota could exceed 60 degrees.

A cold front will cross Minnesota on Wednesday evening. Thursday’s high temperature in the Twin Cities can be around 40 degrees (around 1 a.m.), with temperatures dropping into the 20’s for Thursday daylight hours. Metro tops will be in the mid-20s on Friday.

Wednesday rain and snow potential

A strong low is expected to pass through Minnesota on Wednesday afternoon and evening. NOAA’s North American Mesoscale Forecast (NAM) model shows the track of the low and the potential precipitation regime from Wednesday noon through Wednesday evening:

At this point, it looks like the Metro Twin Cities area will have a chance of rain showers Wednesday afternoon, followed by a good chance of rainy spells Wednesday evening and Wednesday evening overnight. There might even be a thunderclap. There will be a risk of rain showers or flurries in the metro area late Wednesday evening through early Thursday.
