The storm will spread into Ontario and the western side of Quebec Saturday.
The storm has had a history of producing up to 8 inches of snow. That happened in North Dakota Thursday night and early Friday. Over the next 24 hours, 3 to 6 inches of snow will fall in places like Duluth, Minn., Marquette, Mich., and North Bay, Ontario.
Somewhat to the South, it's been a very rainy day from central Minnesota and Wisconsin to Lower Michigan. That soaking rain area will work eastward through upstate New York into northern New England Friday night and Saturday.
In the Ohio Valley and up to the mid-Appalachian region, an outbreak of severe thunderstorms will cause trouble into the overnight hours. The storms will produce straight-line wind gusts over 60 miles per hour and probably a few tornadoes.
The passage of the storm will be followed by a turn to much chillier weather.
In southern Ohio, for instance, temperatures reached the lower 80s Friday.
Saturday, it will only be in the 50s there. The cooldown will be widespread, affecting a broad area from the central Appalachians and the Ohio Valley southward to the Gulf states.
Then of course there is the wind aspect of the storm. High winds (gusts over 40 miles per hour) will impact the Midwest overnight, then hit the eastern Great Lakes and mid-Atlantic region Saturday.
