Special Weather Statement issued March 17 at 11:07AM EDT by NWS State College PA

Summary: Cold air moving in will help to generate scattered to numerous snow showers and possibly some dangerous snow squalls today across Central Pennsylvania. West to east oriented bands of snow showers will increase in coverage amidst partly to mostly cloudy skies. Road surface temperatures will soar into the 40s and 50s while air temperatures remain below freezing. Snowfall accumulations of a coating to 2 inches are possible across the area as a result of these snow showers. More persistent bands of snow may initially melt on contact with warm roads and then freeze, resulting in icy conditions. In the event that a flash freeze becomes likely, Snow Squall Warnings will be issued to message the reduced traction and blinding visibility of a snow squall, which can make travel very dangerous very quickly. Be alert for changing conditions today if you are traveling. Partly cloudy skies can give way to significantly reduced visibility very quickly. If a Snow Squall Warning is issued, delay travel or exit the highway at the next opportunity. 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.
