The western Pennsylvania area is expecting a winter system to move in late Wednesday night that could bring several inches of snow to some areas. The system will move in around 9 p.m. north of I-80, which will quickly spread with heavy snow and move out by 3 a.

On Wednesday at 3:29 p.m. an updated winter storm warning was issued by the National Weather Service valid from 4 p.m. until Friday 1 p.m. for Clearfield, Cambria and Somerset counties.

Over 6 inches of snow is possible in parts of Pennsylvania, including the Pocono Mountains, as a winter storm brews in the Northeast.

Parts of the Great Lakes region will continue to be battered by lake-effect snow, with warnings in place into Friday. See the forecast.

Winter storm watches continue for parts of New York, Michigan, Pennsylvania and Ohio on Wednesday, where lake-effect snow is expected to wallop parts of the Great Lakes region, while a good portion of the continental United States is experiencing bitter-cold temperatures.

Another round of lake-effect snow is on the way Wednesday night into Thursday, with near-blizzard conditions and up to a foot of additional snow for some in the Great Lakes and Northeast regions. The latest batch follows bands of extreme snowfall that have dumped a widespread 3 to 5 feet of snow in the region near Lakes Erie and Ontario.
