 Nor’easter To Bring Heavy Snowfall To Eastern US

 

A strong winter storm continues to move through the Southeastern US.  Later today it will track through Carolina’s and wrap up into an impressive cyclone which will hammer the eastern US coastline overnight.  There will be some challenging forecasts as to what type of wintry fun the storm will leave as precipitation falls into temperatures near or below freezing.  Ice, freezing rain, and snow should accumulate heavily on trees and powerlines, causing outages as the storm races up the east coast early Thursday morning.   Some rainfall is possible along portions of the immediate coast as the storm wraps in warmer air with a trajectory coming off the Atlantic.  Otherwise a wide swath of snowfall accumulating to more than 6″ should set up over all the eastern US coastal states.   There will likely be many locations, including highly populated cities along and near the coast that see more than 10-14″ of snowfall.   Strong winds gusting over 30-40 mph should also accompany snowfall, leading to localized blizzard conditions.   After the Nor’easter passes, a fresh Canadian clipper will be quick to follow Friday with a reinforcing blast of very cold temperatures as well as a fresh dusting of snowfall to pretty things up.  The following images highlight the track of the storm and total rainfall and snowfall amounts.

 

The image shows the weather pattern just off the surface of the ground.  There are two storms of interest on the map.  The first is the strong storm riding up the Northeast coast.  There is a nice slug of warm air wraping into the storm and this could push into portions of the Northeast coast which could lead to some rain right near the coast.  The Nor'easter will track right next to the coast and just a slight shift by a few miles either way could bust a forecast.  Also note the low pressure system moving through the Midwest.  This system is tapping much colder Canadian air so in addition to band of light snowfall setting up there will also be a reinforcing blast of some pretty cold air which will impact the highest use states of the Northern US this weekend.

The chances of a wide swath of the Northeast receiving more than 4″ of snow is very high.

 

The latest morning forecast data continues to advertise heavy precipitation along the eastern US coastline.  The image shows total rain or melted snow over the coming 48 hours.  Yellows into oranges represent more than an 1" of water, which if falling as all snow could easily accumulate to a foot or more.  There will be a sharp drop off on precip amounts heading inland.

The latest model projected snow amounts bring a wide swath of more than 6" across the eastern US over the next 48 hours.  There will be some areas right along the immediate coast where snow may mix or turn over to rain. The image shows snow in inches where whites into oranges show more than 6" of snow accumulations.
