A persistent veil of clouds hung over southeast Minnesota overnight. Scattered flurries lingered as well. Cloud cover was sufficient to hold surface temperatures in the middle teens.
See the thicker moisture layer (often an indicator of clouds) over southeast Minnesota, as shown on the water vapor satellite image from early this morning.
This map from the Rapid Update Cycle (RUC) depicts the the surface temperatures and wind from 3AM.
Some of the colder temperatures in the state in the overnight hours; 15 below zero at International Falls, Cook, Ely and Hibbing. It tumbled to six degrees below zero at New Ulm.

A bump up in temperature takes place on Wednesday before another shot of colder air arrives on Thursday. Not shown is the moderation on Sunday.
But what I have for you here is the surface map of temperatures and wind from Twister.com from the GFS model for Sunday at noon. Not much in the way of arctic air in the continental USA.
Checking back on the winter of 2010-2011 I counted 18 days of sub zero temperatures reported at the Twin Cities International Airport. The coldest temperature of last winter at the big airport was 16 degrees below zero on January 21st.
By the way, Louisville has a new annual precipitation record. After accumulating a daily record of over two and a quarter inches of rain on Monday, they are now up to 65.70 inches. Compare that to the year to date total of 26.15 inches at Minneapolis International Airport.

From this visible satellite image taken around 3PM you can clearly see the band of snow through southeast Minnesota. Clouds obsure the snow in the far southeas corner of the state. High clouds were already advancing quickly across northwest Minnesota.
The Chanhassen NWS Office posted an annotated image on their website.
Another cold front is tracking in our direction. After a little gain on the thermometer on Wednesday, we'll be looking at the good chance for more sub zero readings on Friday morning. This morning it was a nippy 17 degrees below zero at Babbitt and Cook in northern Minnesota. Princeton was down to 1 below zero around daybreak.
Clouds and a few theatrical quality flurries kept temperatures from dipping much below the middle teens from the Twin Cities to Caledonia.
Little if any snow is on tap for the rest of the week. Models have been consistent with a moderation to at or slightly above the thawing point on Sunday. Here's a look at the GFS model surface temperatures and wind for noon on Sunday.
Might as well jump ahead to next week and get an idea for temperatures for the middle part of December. Normal temperatures continue the steady decline as we move towards the heart of winter. Normal highs slip into the 20s with lows dropping close to the single digits.
