Colder air will plunge into the northeastern United States and set the stage for a snowstorm in part of the region from Sunday into Monday.
The exact track of the storm is dependent on a number of variables, which have yet to fall into place. However, the storm is likely to track close enough to the Atlantic coast to bring accumulating snow to the Interstate 95 corridor.
This map shows the anticipated accumulation on non-paved surfaces. The accumulation on roads may be significantly lower, especially in the mid-Atlantic.
"There has only been one storm that turned out to sea this winter, so we are fairly confident this one is coming up near the coast," AccuWeather Senior Meteorologist Bernie Rayno said.
"A true shot of arctic air, impressive for March, will push southward and set the stage this weekend," Rayno said. "For areas that get into the arctic air, this will be primarily a snow event."
The approximate southern edge of the arctic air will be between Richmond, Virginia, and Washington, D.C.
The storm will gradually strengthen while traveling northeastward near the coast during Sunday and Monday.
The amount of snow that falls will depend on the storm intensity as it passes by.
During the day Sunday, the storm will be relatively weak. Some of the snow that falls will melt on warm, paved surfaces in the mid-Atlantic. The storm can be mixed with rain for a time in the coastal mid-Atlantic.
As the storm begins to strengthen during Sunday night, the rate of snow may be heavy enough to make for slippery conditions in the mid-Atlantic, before dry air sweeps in.
"The best setup for a nor'easter with heavy snow will be farther to the northeast," Rayno said.
The rate of snow is likely to ramp up significantly near New York City during Sunday night.
"If the storm develops to its full potential, then a blizzard could evolve in part of New England," Rayno said.
Since the storm will be strengthening while impacting New England, it could bring heavy snow, increasing wind and building seas with worsening travel conditions.
The bulk of the storm will affect New England Sunday night into early Monday, when road surface temperatures will be at their lowest.
The amount of snow expected to fall near and west of the I-95 mid-Atlantic cities is not set in stone at this point as there are many factors that will come into play.
AccuWeather will continue to provide updates on the storm, including the extent and amount of snow and coastal problems as more information becomes available.
Rather than cold weather locking in for an extended stay, temperatures will rebound next week and will cause the snow that falls to rapidly melt.
