Snow squalls are considered by the National Weather Service to be "one of the most dangerous winter weather phenomena."
"Although snow accumulations are typically an inch or less, the added combination of gusty winds, falling temperatures and quick reductions in visibility can cause extremely dangerous conditions for motorists," the service wrote on its website. By the evening, some of the squalls had cleared. Snow squall warnings were in effect as an arctic front brought intense bouts of heavy snow and strong winds to portions of Pennsylvania, New Jersey, New York and Massachusetts on Saturday afternoon, the National Weather Service said.
