Share story

We finally did it!

Shortly before 8 this Saturday morning, the temperature dipped below zero at Minneapolis-St. Paul International Airport:

This sets a new record (Jan. 19) for the latest first sub-zero reading of winter in the Twin Cities.

According to the Minnesota State Climatology Office, January 18 is the previous date of our latest first sub-zero reading of winter in the Twin Cities:

We came close to a sub-zero temp at MSP airport on New Year's Day this year, with a low of zero.

Snowstorm tally

As expected, the highest snowfall totals Friday and Friday evening were in far southern Minnesota.

Observations are collected from a variety of sources with varying

equipment and exposures. We thank all volunteer weather observers

for their dedication. Not all data listed are considered official.

I've also noticed the following totals: 15 inches about 8.5 miles north of Heron Lake (and to the west of Windom) in southwestern Minnesota. Rochester tallied 8.1 inches of snow on Friday.  You notice that snow amounts drop off as you move north: Mankato reported 5 inches of snow, and 3.5 inches accumulated in New Prague. In the south metro, Carver reported 2.4 inches, and Lakeville came in with 2.1 inches. Minneapolis-St. Paul International Airport measured only two-tenths of an inch, and it was their first measurable snowfall of this month.  Our season snowfall of 11.2 inches at MSP airport is 17.8 inches below normal to this point in our snow season.

This note from the NWS:

You can check snow accumulations for Minnesota and western Wisconsin as they are posted by the NWS. Hover over a location on the NWS snow map to see the snow total and the time of observation. If you are looking at the NWS map late Saturday or beyond, you may want to click the "last 48 hours" tab to capture snow reports since early Friday.

You can also see updated snow totals posted as public information statements and as local storm reports.

Cold weekend

Saturday afternoon highs are expected to range from the single digits below zero in far northern Minnesota to the lower teens in the far south.

Lows late Saturday night into early Sunday will be well below zero in northern Minnesota and parts of central Minnesota:

Wind chill temps in the -35 to -45 range are expected overnight and early Sunday in much of northeastern Minnesota, and International Falls could see their wind chill dip to -52:

NWS Duluth

Sunday highs will be mainly in the single digits across Minnesota, with some teens from the Twin Cities into southeastern Minnesota:

rt120h5

Twin Cities metro area highs are expected to be around 20 Monday and Wednesday, with lower 20s on Tuesday. Teens look possible on Thursday, followed by single-digit high temps on Friday.

Our average high this time of year is 24 degrees in the Twin Cities metro area.

Snow chances

West-central and southwestern Minnesota, plus areas along the North Shore of Lake Superior, will have the best chance of light snow showers Sunday and Sunday evening.

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

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.

Periods of snow are expected across much of Minnesota and western Wisconsin on Monday and Tuesday:
