Warmer with some light snow or freezing drizzle tonight and Thursday (winter weather advisories in effect for parts of the Northland) Some lake effect snow possible this weekend

-Winter Weather Advisory in effect until 4 PM Thursday for the North Shore of Lake Superior including the cities of Two Harbors, Isabella, Finland, Silver Bay, Tofte and Grand Marais.

-Winter Weather Advisory for parts of northwest Wisconsin in effect from 8 AM to 6 PM Thursday including the cities of Port Wing, Washburn, Bayfield, Ashland, Hurley and Gile.

-Plan on slippery road conditions in the advisory areas. The hazardous conditions could impact the Thursday morning and evening commutes.

-A light glaze of ice accumulation is expected on Thursday in northern Wisconsin along with light snowfall accumulations.

-Snow accumulations ranging from 2 to 6 inches are likely along the North Shore of Lake Superior.

Here’s my snowfall forecast ending at 6 PM Thursday.

*4 to 6 inches of snow in the tip of the Arrowhead including Tofte and Grand Marais.

*2 to 4 inches of snow for International Falls, Cook, Ely and Silver Bay.

*1 to 2 inches of snow for Bigfork, Grand Rapids, Hibbing, Two Harbors, Bayfield, Ashland and Hurley.

*Around an inch of snow for Hill City, Brainerd, Aitkin, Duluth, Superior, Solon Springs, Moose Lake, Sandstone and Hayward.

Should have quite a temperature contrast in place on Thursday with teens in northwest Minnesota and 40s in southern Minnesota.

I’m keeping an eye on the potential for some lake effect snow this weekend. Computer models are starting to agree on the pattern with winds shifting to the east-northeast Saturday into Sunday, this combined with cold air in place and pretty much a wide open lake due to the lack of ice cover could cause lake effect snow showers to affect areas near Lake Superior. Whether this will be a significant lake effect event, or just a minor event is uncertain at this time. Stay tuned.

Some serious cold is forecast to spill into western Canada and the northern Rockies next week with some of that big time cold air possibly pushing far enough to the south/east to impact the upper Midwest sometime mid to late next week.

…Weather Summary…

Arctic airmass will be retreating off to the east this evening and this will be replaced by strong warm air advection and a period of snow tonight as low pressure and a warm front move E-NE out of the Northern Plains.

This same low, warm front and a cold front will pass through the area on Thursday bringing with it some more light snow at times.

Warmer air lifting NE ahead of this system will cause some freezing drizzle/freezing rain on Thursday in parts of northern Wisconsin and possibly in eastern Minnesota as well.

Highs Thursday in the 20s to lower 30s.

South or east winds tonight and Thursday at 10 to 20 mph.

Note: Cold, arctic air returns Friday, but this also doesn’t look to stick around very long as the most persistent arctic air remains bottled up farther to the NW through early next week. The weather pattern does look somewhat active, however, with several shots for some snow this weekend into next week.
