The governor of Pennsylvania has signed a disaster emergency declaration and reported that parts of Erie County in the northwest have received nearly a meter of snow, with more expected to fall until Monday night.

Officials in upstate New York counties have declared a state of emergency as they prepare for a major snowstorm that has already dumped over two feet of snow in the Midwest and is forecast to accumulate more this weekend.

Near Buffalo, between 10 and 20 inches of lake effect snow is expected by the end of Sunday, according to the Weather Service. The southern part of Erie County, along with Wyoming, Chautauqua and Cattaraugus counties, are predicted to see 2 to 4 feet of snow by Monday night.
