Alberta Clipper Not Done Yet
Environment Canada reports, “An Alberta clipper will sail across Minnesota early this morning and then Lake Superior to near Moosonee by this evening. This well developed weather system has a fairly large area of snow associated with it that extends westward all the way to Montana.
A general 15 cm snowfall is expected for most regions. Locally higher snow amounts of 20 to 25 cm are possible over locales along the north shore of Lake Superior, mainly from just east of Nipigon to the Marathon area.
Travel and Road Conditions Update

Hazardous winter driving conditions are expected due to accumulating snow on untreated highways. In addition very low visibility in areas of heavier snow and blowing snow in exposed areas are expected. Motorists should adjust travel plans accordingly and allow extra time to reach their destinations.
The snow will end over Northwestern Ontario this morning and by this evening over regions northeast of Lake Superior. In the wake of the disturbance tonight, very cold Arctic air is expected to return and wind chill warnings may eventually be required to parts of Northwestern Ontario.
