A blast of cold wind picked up moisture from the lakes, bringing it down in the form of snow on the eastern and southern shores from Michigan's Upper Peninsula to western New York.

The National Weather Service said 24 inches of snow has fallen at Constableville, N.Y., downwind from Lake Ontario. Nearly that much snow is on the ground near Buffalo.

Police are reporting a number of accidents on slippery roads in Pennsylvania, Ohio and New York.

The National Weather Service also said a foot of lake-effect snow could fall by Tuesday in several counties in northwest Indiana and southwest Michigan.

It's the first significant snowfall of the season in that area, powered by cold air moving across Lake Michigan. Snow could fall at a rate of 2 to 3 inches per hour close to the lake.

Heavy bands of snow have been moving off Lake Erie, producing several inches of snow in Ohio overnight Sunday. Snow is expected to fall all of Monday, reported WEWS-TV in Cleveland.

Lake-effect snow is falling in Ohio from Cleveland to Parma and Burton to Solon. One of the heavy bands is along Interstate 271. Several accidents have been reported. The Ohio Department of Transportation has crews keeping roadways cleared.

A lake-effect snow warning remains in effect in Ohio until 4 p.m. Tuesday for Cuyahoga, Lake, Geauga and Ashtabula counties.

Lake-effect snow squalls will continue through at least mid-morning Monday. The bands of snow are then expected to weaken for a few hours as an upper-level disturbance passes, WEWS-TV reported. However, by late afternoon another surge of cold air is expected to pass over Lake Erie.

In Ohio, the snow will be heavy at times for late Monday afternoon and especially overnight. Amounts of 6 to 10 inches will be possible through early Tuesday morning. Locally higher amounts in excess of a foot will be possible.

Additional accumulations are expected into Tuesday night before gradually ending on Wednesday.
