- Accumulating snow late tonight into Thursday for all of northwest Wisconsin, and from eastern to northeastern Minnesota. Snowfall rates of up to 1″/hour are possible Thursday morning in parts of northwest Wisconsin.
- Strong northeast winds near Lake Superior of 15 to 30 mph with gusts to 40 mph tonight and Thursday with areas of blowing snow. Winds diminish by mid to late afternoon on Thursday.
- Travel will be difficult in parts of the Northland due to the snow and areas of blowing snow tonight and Thursday.
- Temperatures for areas that will see snow tonight and Thursday will range from the middle 20s to lower 30s.
Lake effect snow showers will be found along the North Shore of Lake Superior and in Duluth this evening, and then will see snow associated with the winter storm over the Plains lift northward into eastern Minnesota and northern Wisconsin after Midnight tonight, and this snow will persist through the day Thursday before ending late Thursday afternoon/evening.
Note — Snow tapers off in Duluth between 6 PM and 8 PM Thursday.
18z NAM 3km model radar forecast through Midnight Thursday night.
The wind direction will be favorable for some lake enhanced/lake effect snow near Lake Superior (yellow outlined area on map) tonight, and then shifting mostly to the South Shore of Lake Superior on Thursday as winds shift more out of the N-NE.
The only real limiting factor for lake effect snow are the 850mb temperatures which are still not that cold, but cold enough to produce some lake effect, and we may see the 850mb temperatures fall a few more degrees later tonight into Thursday, perhaps as low as -10 or -11C which may be a little more favorable for lake enhancement.
Here’s my updated snowfall forecast.
For Duluth — Total snowfall accumulations of 2 to 5 inches by Thursday evening.
