Heavy lake-effect snow band impacting the south shore of Lake Superior today.

Northeast winds and some low-level convergence due to the topography of western Lake Superior has produced a narrow lake-effect snow band over night. The band has been oscillating over the Minnesota counties along the north shore, but has begun shifting south this morning.


As of 7:00, the band began bringing heavy snow to Duluth and points east. This radar image (to the right) is from INFLOW-WI and shows radar echoes at 7:17 this morning.


Some possibly heavy totals today from the Lake.

This graphic (to the left) is from NWS Duluth and shows how much snow is expected from the lake-effect snow today. The heaviest areas are under a Lake-Effect Snow Warning, while the rest of the shoreline is under an Advisory.


It has been three days since our last snow, and we've used the time to plow & shovel our way back to normalcy. The last system was a little harsh with a foot of snow blown by the winds.


So far this winter...

Snow total: 27.1 inches

Max depth: 16 inches

Coldest temp: -18.4 degrees

Coldest windchill: -25.0 degrees

Next storm system is on its way.

Last weekend the northern part of Wisconsin and Minnesota were hammered by a snowstorm, yesterday and today it is the southern parts of Wisconsin that may see up to a foot of snow.


There is no break in the forecast of snow heading our way, and no end in sight to the bitter temperatures either.


This map (to the right) shows where the Hydrometeorological Prediction Center (HPC) has outlined the greatest chances that over 4 inches of snow will fall tomorrow and tomorrow night (Day 2).


Winter Storm Watches in effect.

Most of the region is under a Winter Storm Watch for the next storm, which is forecast to begin tomorrow (Saturday).

In addition to the possible 2 to 5 inches of snow from the lake-effect snow, up to 8 inches are possible from the snowstorm on Saturday and Sunday. NWS Duluth also highlights the possibility of lake-enhancement along the south shore. From their morning discussion:
