The National Weather Service has posted warnings and advisories of winter weather from the Great Lakes Region eastward into New England in anticipation of the first major winter storm this season. Low pressure will track northeast up the Appalachian Mountains overnight and will help to develop a coastal low pressure area south of Long Island, NY. This new low will then track northeast over Nova Scotia later Friday.
With cold air in place over the eastern part of the United States from the synoptic scale pattern, much of this precipitation will fall in the form of snow, except at coastal locations. Even though both low pressure areas will move quickly through the region, they will dump quite a bit of snow and rain.
The latest snowfall forecast for major cities:
Philadelphia: 3 to 7 inches
Washington: 3 to 7 inches
New York: 2 to 5 inches
Albany: 5 to 10 inches
Northwest Boston Suburbs: 6 to 10 inches
