...Lake Superior...
Day 3...

A cold front crosses Lake Superior late Wednesday with a surge of
cold air that drops 850mb temps below 0C by Thursday afternoon. A
reinforcing surge of cold air spreads across the Lake and across
the U.P. of MI into northern WI Thursday night where localized
lake effect snow, enhanced by topographic lift could bring an inch
of accumulation, particularly to the Huron and Porcupine Mtns.
This would be the first accumulating snow of the season.


The probability of significant icing is less than 5%.
