Snow squalls heading for York County, weather service warns
Dangerous snow squalls swept across Pennsylvania on Monday, leading to a pile-up on Interstate 81 in Schuylkill County.
York County was under a snow squall warning until 3:15 p.m. Monday, with whiteout conditions and sudden low traction possible, according to the National Weather Service.
Drivers were warned to delay travel until a snow squall passes. Black ice could cause roads, bridges and overpasses to quickly become slick and dangerous.
York County avoided the worst of the wintry conditions — so far — but nonetheless is forecast to see more winter weather as temperatures dip below freezing each night.
In addition to periods of scattered snowfall Monday with total accumulations up to half an inch, the county will likely see an icy mix of rain, snow and sleet on Wednesday, according to the National Weather Service.
Video posted on social media Monday showed tractor-trailers and other vehicles slamming into other stopped vehicles on I-81 and what appeared to be a tanker truck afire as the panicked onlooker ran from the road for safety.
The National Weather Service had warned of “numerous brief heavy snow squalls with very poor visibility."
“The squalls will quickly reduce the visibility to under one-half of a mile and coat the roads with snow," forecasters said, urging drivers to get off the road if possible or turn on hazard lights “and gradually slow down to avoid a chain reaction vehicular accident."
Mike Colbert, a forecaster with the National Weather Service office in State College, said the weather service just started issuing warnings for snow squalls a few years ago, and pileups of the kind being reported were the reason they began doing so.
“They are very heavy snow showers where if you are driving into them, you can go from partly cloudy or sunny skies into an instant blizzard in a matter of seconds. That’s why they are so dangerous,” he said.
Forecasters, however, call for a return to springlike conditions by week's end, with the high temperature expected to reach into the 70s on Thursday.
