 The center of the system will move northeastward and into eastern Canada. Counterclockwise flow around the system will push warmer air into the extreme Northeast, while cold air continues pouring in behind it. This will allow for rain and freezing rain showers to develop along the
Northeastern coast from Connecticut to Maine, with snow showers likely inland and at higher elevations of the
northern Appalachians. Higher elevations of Vermont and New Hampshire will see another 2 to 4 inches of new snow.
Along the backside of this system, snow showers will cover the Great Lakes, Midwest and Ohio River Valley. Lake-effect snow showers will persist across the downwind shores of the Great Lakes, with 3 to 5 inches likely along the southern shores of Lake Erie, Lake Ontario, as well as the southern and eastern shores of Lake Michigan.
Most of the Midwest will see another 1 to 2 inches of snow on Friday, while the interiors of the Northeast may see up to 5 inches of new snow. Thus, winter weather advisories will remain in effect for most of the Northeast through Friday evening.
Meanwhile, the rest of the U.S. will remain quiet and mild as high pressure covers the West Coast, Rocky Mountains and Plains. This will allow for another sunny and dry day with mild temperatures. However, expect another chilly morning as overnight lows will drop significantly again as clear skies allow for rapid cooling.
In the Pacific Northwest, a trough of low pressure drops in from the Gulf of Alaska late on Friday. This may bring some rain and high-elevation snow showers to Washington Friday night.
Temperatures in the Lower 48 states Thursday ranged from a morning low of
minus 27 degrees at West Yellowstone, Mont., to a high of 86 degrees at Bonifay, Fla.
