A powerful storm will affect the Northeast with heavy rain and strong winds from Monday night to Tuesday. In the wake of the storm, a cold blast will sweep from the Midwest to the Northeast early next week.
The cold air meeting lingering moisture will spur widespread snow showers and heavy squalls from Monday to Wednesday. This poses a danger to highway travel across the region.
Meteorologists warn that snow squalls can lower visibility suddenly, causing slippery roads. Vehicles traveling at high speeds on highways may result in accidents when conditions deteriorate rapidly.
Areas likely to see multiple snow squalls include major interstates in the Midwest and interior Northeast. Cities in the path include Chicago, Detroit, Cleveland, Pittsburgh and more.
Most areas will see light accumulations up to two inches. However, persistent lake-effect snow is probable downwind of the Great Lakes. Also, in the Appalachian mountains and areas south of Buffalo may pick up over a foot.
Accumulations elsewhere should be manageable, but the hazard is reduced visibility from sudden heavy bursts. Even areas as far south as Kentucky and Tennessee could get a slick coating to an inch.
Temperatures Set To Plunge Behind The Storm
A powerful storm tracking up the East Coast will tap into unusually warm air, sending temperatures surging to mid-December record levels early Monday. Highs from the Midwest to Northeast will top out 15-25 degrees warmer than average ahead of the system's cold front.
But the mild air will get shoed eastward by Monday night as cold air pours southward behind the departing storm.
Readings will spike into the 60s as far north as New York City and Philadelphia during Monday morning. The urban heat island effect will allow coastal locales to briefly reach mid-autumn levels for the middle of December.
However, the warmth will vanish swiftly by the afternoon as winds shift to the northwest. Temperatures in the I-95 corridor will plunge into the 30s, making it feel over 20 degrees colder compared to the morning's highs.
