Early winter: 2 to 4 inches likely south of the Twin Cities

Weather maps look more December than November.

Winter is here early this year.

Our fleeting six-month 2019 warm season is gone. The cold air in place is ready to yield the season’s first plowable snow for southern Minnesota.

A winter weather advisory is posted for southern Minnesota Tuesday night into Wednesday. It includes the cities of Mankato, Waseca, Owatonna, Blue Earth, and Albert Lea

Twin Cities rides northern edge

The bulk of forecast models agree the Twin Cities will ride the northern edge of the snow zone. National Oceanic and Atmospheric Administration’s Global Forecast System model is typical of those placing the heaviest snow across southeast Minnesota with the northern edge of the snow band right through the Twin Cities.

The European Centre for Medium-Range Weather Forecasts model snowfall output suggests around one-half inch for much of the Twin Cities, with 2 to 4 inches south. Little or no snow is expected in the northern Twin Cities.

Record cold next week?

This deep pool of cold air extends all the way to Alaska.

That’s going to keep Minnesota running a good 10 to 20 degrees lower than average.

Temperatures next week may approach record cold levels in Minnesota with sub-zero readings up north and low temperatures close to zero in the Twin Cities.

I know. It’s like, November. Not January.

Stay tuned.
