Special Weather Statement issued December 31 at 7:40PM EST by NWS State College PA

Summary: A strong cold front moving in will help to generate a line of heavier snow showers and possibly embedded dangerous snow squalls across northwest and central Pennsylvania. We expect heavy snow showers and possible squalls to be on a line from: * Near Coudersport to Bradford to Warren between 10 and 11 pm. * Near Mansfield to St. Mary's to Dubois between 11 pm and midnight. * Near Jersey Shore to Lock Haven to Clearfield between midnight and 1 am. * Near Williamsport to State College to Altoona to Somerset between 1 and 2 am. * Near Bloomsburg to Harrisburg to Mechanicsburg between 2 and 3 am. * Near Lancaster to York between 3 and 4 am. If snow squalls develop, they will last for up to 10 to 15 minutes in any one location, with up to a half-inch to an inch of snow in that timeframe, along with possible wind gusts of 30 to 40 mph. This would result in a quick reduction in visibility and perhaps localized icy roads, should a flash freeze develop. Low traction and blinding visibility of a snow squall can make travel very dangerous very quickly. If this combination of ingredients becomes imminent, snow squall warnings would be issued, with very specific information on timing, movement, and portions of interstate highways to be affected. Please monitor the latest conditions in your area overnight if you will be out driving. Use extra caution if you must travel into a snow squall, slow down, and consider exiting the highway. Rapid changes in visibility and potentially slick roads may lead to accidents. Please use extreme caution and allow plenty of stopping distance. Avoid braking suddenly.
