Friday night and Saturday, a significant amount of snow will fall innorthern Minnesota, northern Wisconsin, and on the Upper Peninsula of Michigan.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 happenedin North Dakota Thursday night and early Friday. Over the next 24 hours, 3 to 6inches of snow will fall in places like Duluth, Minn., Marquette, Mich., andNorth Bay, Ontario.

Somewhat to the South, it's been a very rainy day from central Minnesota andWisconsin to Lower Michigan. That soaking rain area will work eastward throughupstate New York into northern New England Friday night and Saturday.

In the Ohio Valley and up to the mid-Appalachian region, an outbreak of severethunderstorms will cause trouble into the overnight hours. The storms willproduce straight-line wind gusts over 60 miles per hour and probably a fewtornadoes.

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 Valleysouthward to the Gulf states.

Then of course there is the wind aspect of the storm. High winds (gusts over 40miles per hour) will impact the Midwest overnight, then hit the eastern GreatLakes and mid-Atlantic region Saturday.
