Thanks to the NWS-Duluth for the storm report. Needless to say, we did not fully forecast 4'+ of snow! Most of this rapid accumulation is due to lake effect bands, associated with the surface cyclone as is continues to push off to the northeast!
A couple inches of snow are likely Saturday into Sunday from Iowa to Wisconsin and Illinois, as a weak trough passes through the area. Temperatures continue to stay cold with strong blocking in the North Pacific.
