Up to 2.5 feet of new snow has fallen across the typical snowbelts downwind of the Great Lakes since Sunday.

While the heavy snow is winding down downwind of Lake Michigan and Lake Superior, accumulating snow will persist downwind of Lake Erie and Lake Ontario through Wednesday.

Along with the snow, frigid winds blowing out of the northwest will create whiteout conditions at times, adding to travel headaches.

Travel will continue to be extremely dangerous along portions of I-79 in northwestern Pennsylvania and I-90, the New York State Thruway through Wednesday.

Some locations downwind of the Great Lakes have already received upwards of 2.5 feet of new snow the last couple of days. Selected snowfall totals from Sunday through Tuesday morning include 25.2 inches in La Porte, Ind., 24.3 inches in Wanatah, Ind., 20.0 inches in Perrysburg, N.Y., and 18.3 inches in New Buffalo, Mich.

Cities that may receive additional heavy snow tonight and Wednesday include Erie, Jamestown and Syracuse.

In Pittsburgh, the heaviest of the snow will be winding down through tonight with additional accumulations expected to be confined to areas north and east of the city.

Farther east, in the higher elevations of southwestern Pennsylvania and West Virginia, up to an additional 3-6 inches of snow will pile up with the heaviest amounts on the ridge tops.

In New York, ski areas south of Buffalo will get hit harder than the city, with another 6-12 inches of snow forecast in the most persistent bands.

Not only will the snow continue to pile up in select locations, but arctic air discharging southward from Canada will keep temperatures running 15-20 degrees below normal. Temperatures in the teens and single digits combined with wind gusts of 30-40 mph will continue to produce AccuWeather.com RealFeel® temperatures of -5 to -15 degrees throughout the Great Lakes.

Aside from causing treacherous travel, the snow and cold will continue to cause disruptions in daily activities through Wednesday. School and activity cancellations are likely to impact the hard-hit communities downwind of the Great Lakes.
