I tell ya these systems this winter have been difficult to forecast.  Computer models have been going back and fourth in the amount of precipitation/snow that falls with this system late tonight and Tuesday, the trend today is for slightly more precip/snowfall once again.  The image below is my snowfall map through Tuesday afternoon.

-I'm thinking 3 to 5 inches of snow in the Twin Ports but there is a low chance for higher amounts if we get some lake enhancement which is a possibility through early Tuesday afternoon as winds will be out of the east/northeast til then.

Weather Synopsis for northeast Minnesota and northwest Wisconsin

Mostly cloudy skies covered most of the area today although there has been some breaks in the clouds allowing for a bit of sun to appear especially in east central Minnesota and northwest Wisconsin.

Light snow has been affecting portions of northern Minnesota since last night with new snowfall accumulations in the 1 to 4 inch range through this morning -- Most of the snow has ended this afternoon outside of a few pockets of light snow here and there.

Highs today ranged from the teens in northern Minnesota with mid 20s and low 30s in eastern Minnesota and northwest Wisconsin.

More snow is on the way!

Low pressure over the central Plains this afternoon will deepen a bit as it lifts northeast to southern Lake Michigan by Tuesday afternoon -- This low combined with a disturbance heading east out of the northern Rockies will go on to produce light to moderate snow across the Northland beginning later this evening and lasting into Tuesday.

In addition to the system snow, there is a potential for some lake enhanced snowfall around Lake Superior with east or northeast winds through Tuesday morning before the wind shifts to the north or northwest Tuesday afternoon which will end the threat for lake enhanced snow along the North Shore while it continues along the South Shore.

Lows tonight will range from the single digits and teens in northern Minnesota to the 20s in northwest Wisconsin.  Highs on Tuesday will be in the teens in northern Minnesota to near 30 degrees in parts of northwest Wisconsin.

Roads will remain or become snow covered and slippery later tonight into Tuesday in parts of northeast Minnesota and northwest Wisconsin.  Visibility will be reduced to less than a mile at times due to the falling snow.  Also, gusty northeast winds near Lake Superior will produce areas of blowing and drifting of the snow late tonight through midday Tuesday.

Note:  There could also be some patchy freezing drizzle mainly from east central Minnesota into northwest Wisconsin tonight and Tuesday morning.

Another shot of cold arctic air will move into the Northland for Wednesday and Thursday with highs in the single digits on Wednesday with lows Wednesday night in the single digits, teens and 20s below.  Highs on Thursday will be in the single digits and teens.

A quick rebound in temperatures is expected on Friday as a vigorous clipper like system heads into the upper Midwest -- This system could bring some light snow or a wintry mix of precipitation to parts of the Northland on Friday but there is a chance that most of this precipitation will stay north of the border.  Highs on Friday will warm into the 40s and 50s in western-southern portions of Minnesota while here in our area highs will be cooler in the 20s and 30s.
