Snow will spread across the northern Great Lakes tonight as another shot of cold air arrives from Canada. Winds will also increase from the northwest, gusting 20 to 30 mph, with gusts over 40+ mph possible near the coast.
Due to the combination of wind and snow, this will result in areas of low visibility and hazardous travel. The National Weather Service has issued a winter weather advisory due to the expected hazardous travel. This advisory will be in effect through early Wednesday morning.
The heaviest snowfall rates will occur between 7pm this evening and 1am Wednesday. Snow accumulations will be the greatest across northern Michigan, and that is where 3 to 7 inches of snow is expected. Lingering lake effect snow showers will continue into the day on Wednesday, with some additional accumulations possible.
The storm system will continue into northern New England on Wednesday as it dives out of Canada, and redevelops over the Gulf of Maine. Winter storm warnings and advisories have been issued ahead of this next system.
Moderate to heavy snow accumulations are possible in the Northeast. This will also add to the running total that has seen many areas receive nearly three feet of snow in the last week. The weight of the recent snowfall may become a hazard for some rooftops. Also, heavy wet snow near the coastline may lead to isolated power outages if snowfall starts to bring down tree limbs.
