It’s been a wintry December so far for Minnesota. Temperatures are running 11 degrees colder than normal through this first half of December in the Twin Cities.

The coldest air mass so far this season made us bottom out at minus 11 degrees at Minneapolis-St. Paul International Airport Sunday morning. The suburbs hit minus 15 degrees Sunday morning with minus 28 in the north.

So far, we’ve recorded four nights of subzero temperatures in the Twin Cities. The seasonal average is 22 subzero days over the course of a Twin Cities winter.

Minnesota turns blustery and colder behind the system Thursday into Friday. At this point, the weekend looks quiet with highs in the 20s.

Early indications for Christmas week favor highs in the 20s and 30s. Right now, I don't see any big snowstorms on the map for Christmas week, but it’s still early.

Stay tuned.
