A little snow possible Monday; A stronger clipper arrives Tuesday with some accumulating snow, arctic air to follow

4:01 PM Sunday, January 16, 2022

A frontal boundary draped over the Northland combined with a weak area of low pressure moving along this boundary may bring just enough lift to squeeze out a little snow from time to time during the day Monday, but snowfall amounts are expected to be <1″ on Monday.

There is a greater chance for a more widespread snow event on Tuesday and will likely have to deal with gusty winds and some blowing snow Tuesday night into Wednesday as arctic air returns to the Northland.

Here’s the 18z NAM 3km model simulated radar forecast valid Midnight tonight to Midnight Monday night (snow in blue colors)

TUESDAY CLIPPER

  • Accumulating snow is likely in much of the Northland on Tuesday
  • Highest amounts (4+”) are forecast to be over far northern Minnesota and over the Arrowhead
  • Lesser amounts of snow are expected Tuesday farther south including for Duluth and all of northwest Wisconsin
  • Gusty winds with areas of blowing snow Tuesday night into Wednesday morning
  • Falling temperatures Tuesday evening as an arctic air mass moves in

Here’s my preliminary snowfall forecast for Tuesday

A winter storm watch has been issued for the Arrowhead of Minnesota this includes portions of the North Shore of Lake Superior from Tuesday morning through Tuesday evening.

Some cities included in this winter storm watch — Tofte, Lutsen, Grand Marais, Hovland and Grand Portage.

IMPACTS — Heavy snow possible. Travel could be very difficult.

GUSTY WINDS TUESDAY NIGHT

A tight pressure gradient develops Tuesday night as strong low pressure exits off to the east while a strong arctic high builds in from the northwest, this coupled with a shot of strong cold air advection should cause some gusty winds across the Northland Tuesday night into Wednesday morning with wind gusts of 20 to 35 mph possible. Areas of blowing snow may develop Tuesday night due to the gusty winds.

ARCTIC AIR RETURNS THIS WEEK

A fresh blast of icy cold air is set to return to the Northland mid to late week, with Wednesday and Thursday likely to be the coldest days this week with high temperatures on those two days only in the single digits below to single digits above zero.

Lows Wednesday morning are forecast to range from around -10 to 5 above zero in northeast Minnesota and northwest Wisconsin, with even colder overnight lows likely for Thursday morning and Friday morning as temperatures fall to between -15 to -30 degrees, and it may be even colder than that in the typical cold spots in our area.

Dangerously cold wind chills are possible as well from Wednesday into Thursday.
