HARRISBURG – The National Weather Service has issued a hazardous weather outlook for Central Pennsylvania for today and tonight, with possible scattered snow showers and a heavier snow squall this evening.
Forecasters are predicting an artic cold front will cross the region late this afternoon bringing scattered snow showers and possibly a brief heavier snow squall, which could affect the evening commute.
According to the NWS, a snow squall is a brief but intense period of heavy snow (up to 2 inches in 30 minutes), strong winds (30+ mph), and whiteout conditions (visibility less than ¼ mile). Snow squalls often occur on days with otherwise partly cloudy skies. Coming on so suddenly, snow squalls can catch drivers off guard and lead to major transportation impacts, including deadly multi-vehicle accidents.
“We all have a role to play in staying safe on roadways this winter,” said PEMA Director Randy Padfield. “When you get a snow squall warning, the safest thing to do is pause your travel to keep yourself and your loved ones safe, which will help first responders too.”
“One of the things that makes snow squalls so dangerous is their tendency to produce icy roadways, or what we call a flash freeze,” said NWS Meteorologist John Banghoff. “Because they come on so suddenly, snow squalls can catch drivers off guard and lead to major transportation incidents, including deadly multi-vehicle accidents.”
“The National Weather Service issues Snow Squall Warnings to alert for the sudden onset of life-threatening conditions encountered by highway travelers during snow squalls,” said NWS State College Warning Coordination Meteorologist Jonathan Guseman. “If you are driving on an interstate when a Snow Squall Warning is issued, the best thing to do is gradually reduce your speed and exit the roadway at the next opportunity.”
“PennDOT is prepared for the season and actively monitors conditions and forecasts, but we cannot prevent snow squalls or know exactly where they’ll hit,” PennDOT Acting Deputy Secretary for Highway Administration Mike Keiser said. “If you must travel in inclement weather, please allow plenty of space around other vehicles and our snow-plow operators so they can perform their jobs effectively and safely.”
“If you are caught in a sudden snow squall, it’s important to remain calm and not panic,” said Mark Compton, PA Turnpike Chief Executive Officer. “Don’t slam on your brakes, stay in your lane and slow down to leave plenty of distance between you and the vehicle in front of you. Also, turn on your head lights and hazard lights so others can see you. If you are on the PA Turnpike, dial *11 on your cell phone if you are in need of assistance.”
“Snow squalls have led to major pileup crashes with multiple injuries and deaths, ” said Major Robert Krol, Director of the Pennsylvania State Police Bureau of Patrol. “If you are involved in a pileup crash, do not stand outside your vehicle if it is on or near the roadway. Instead, seek a safe place well off the roadway behind a guide rail, a concrete barrier or a large tree and if there is no safe place, stay in your vehicle with your seatbelt fastened.”
