A fast-moving storm system will produce a swath of accumulating snow from the central Appalachians to parts of the mid-Atlantic and southeastern New England from Tuesday to Tuesday night. Commuters in the northern and western suburbs of the I-95 corridor from central New Jersey to Washington, D.C., will be at higher risk of experiencing slippery travel and reduced visibility since precipitation is more likely to fall in form of snow and road surface temperatures area likely to be a few degrees lower.
The storm is expected to race to Atlantic Canada by Wednesday morning.
Accumulating snow will be able to occur farther south and east than what has occurred so far this winter due to the storm’s more southern track.
Travel along portions of Interstates 64, 68, 77, 79 and 81 will be slippery and dangerous over the mountains and through the Shenandoah and Roanoke valleys.
While the storm is likely to start as rain or a mix of rain and snow in much of the I-95 swath, a general coating to an inch of snow is forecast from Washington, D.C., to Baltimore; Philadelphia; New York City; Hartford, Connecticut; Providence, Rhode Island; and Boston. While most of the snow in these urban areas will be on non-paved surfaces, a small, slushy and slippery accumulation can occur on roads and sidewalks, especially on bridges. Outside of the downtown areas, the amount of snow accumulation will increase.
From 1 to 3 inches of snow is expected to focus over parts of the central and southern Appalachians with an AccuWeather Local StormMax™ of 8 inches over the West Virginia mountains.
Snow, or a mix of rain and snow, will only fall for a period of around six hours in most locations, which will limit how much accumulates.
Commuters in the northern and western suburbs of the I-95 corridor from central New Jersey to Washington, D.C., will be at a much higher risk of experiencing slippery travel and reduced visibility since precipitation is more likely to fall in the form of snow and road surface temperatures area likely to be a few degrees lower.
