Temperature forecast from 7 PM Monday to 7 PM Tuesday — It’ll be a relatively mild night across the Northland with lows eventually falling into the mid teens to mid 20s (Normal lows in early January range from the single digits below to single digits above zero) Colder air hits Tuesday as temperatures hold steady or fall into the teens, which is pretty much where we should be for high temps in early January.

It’s gonna get windy! Here’s the wind gust forecast valid from Midnight tonight to Midnight Wednesday. Strong cold air advection moving into the region will help produce gusty winds out of the NW on Tuesday.

Weather Synopsis for Northeast Minnesota and Northwest Wisconsin
Very mild temperatures continued today with highs mainly in the 30s. The storm which brought heavy snow to the North Shore and Arrowhead and mixed precipitation elsewhere has exited to the east this afternoon with low pressure near Marquette, Michigan as of 5 PM Monday.
The airmass behind this system isn’t particularly cold (yet) with 850mb temperatures of 0 to +2C across the Northland late this Monday afternoon.
A push of strong cold air advection will occur late tonight-Tuesday morning as 850mb temperatures fall to around -10 to -20C!
A strong area of low pressure will move east out of Manitoba province today and will reach the southern shores of Hudson Bay Canada by Tuesday evening. A cold front attached to this low will head SE and through the Northland late tonight. This front along with a changing airmass from warm to cold could help generate some snow showers and flurries late tonight into Tuesday but we shouldn’t see any accumulation out of this.
Lows tonight will be in the teens and 20s with nearly steady or slowly falling temps on Tuesday.
Looks mainly dry for midweek and it will be chilly, but milder temperatures are expected to return once again this weekend, along with that could come some snow as a system approaches from the W-NW. Lake effect snow is also possible near Lake Superior Friday and Saturday, but wind direction will determine if this impacts the North Shore or South Shore. Easterly wind would cause lake effect snow along the North Shore, but a northerly wind would focus the lake effect snow along the South Shore.
