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.

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.

The cold front will move across the Great Lakes into northeastern states by Thursday, bringing likely hazardous travel conditions.

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.
