Here’s my updated snowfall forecast through Thursday afternoon.

Greatest amounts of 2 to 4 inches in far northern Minnesota including the cities of International Falls, Littlefork and Big Falls.

1 to 2 inches of snow for Bigfork, Orr and Cook.

Lesser amounts of snow of an inch or less farther south.

Note: A wintry mix of precipitation is also expected in parts of northern and northeast Minnesota tonight with ice accumulations of up to one tenth of an inch possible especially along the Higher Terrain along the North Shore of Lake Superior and also around the Brainerd Lakes area.

A potentially stronger storm may affect the Northland this weekend.

Possible impacts include

-Wet heavy snow (6 to 10″+ accumulations)

-Rain

-Sleet and freezing rain (possible ice accumulations)

-Lakeshore flooding along the North Shore and South Shore of Lake Superior.

-East/northeast winds 20 to 45 mph near Lake Superior late Saturday into Sunday.

Note: There remains quite a bit of uncertainty in model guidance on the track and timing of this system, and whether or not a dry slot will work far enough north to impact parts of the Northland which would shut-off the precipitation for a little while should this dry slot affect our area.

Stay tuned!
