PITTSBURGH — (WPXI) – Winter gave us a chilly reminder that it’s not over yet. A sudden blast covered many neighborhoods in snow Wednesday morning and afternoon. Another system moving in is expected to drop several inches of snow on Saturday. Early indications are that parts of the region could get anywhere from 3 to 6 inches of accumulation. Moderate to heavy snow is expected. Travel will be difficult as road crews try to keep up. Expect the forecast to change slightly here and there as we get closer to Friday.
