Persistent heavy snowfall will continue through late afternoon across the Lower Susquehanna Valley and the south-central mountains. Widespread hourly snowfall rates of 1-2 inches can be anticipated, with locally up to 3 inches per hour possible. Travel will be very difficult for the evening commute, with poor visibilities of less than a half-mile, and snow covered roads. This includes the Pennsylvania Turnpike, along with portions of Interstates 78, 81, and 83.
