Snow, wintry mix to swipe mid-Atlantic into Saturday night

While the northeastern United States will escape a major nor'easter, a storm will still sweep snow and a wintry mix in the southern mid-Atlantic through Saturday night.

A press of colder, drier air is having enough influence to prevent a heavy snowfall for the mid-Atlantic this weekend. However, parts of the region still will get accumulating snow.

Snow first fell across the Ohio Valley and interior Northeast on Friday night, bringing some areas a coating to several inches of accumulation, including in Pittsburgh.

The potential for accumulating snow shifted to northwestern North Carolina on Saturday. Up to a few inches of snow can whiten these areas into the evening hours.

The best chance of an accumulation will be on grassy surfaces, but the snow may accumulate on roadways even during the day if it manages to fall at a moderate to heavy pace.

The corridor from Washington, D.C., to Baltimore will not have to deal with any accumulating snowfall as the storm passes by to the south.

During Saturday night, enough cold air may be pulled into the storm for snow to coat the ground and create slick spots across north-central North Carolina and south-central Virginia.

Rain may also mix with or end as wet snow or ice pellets in southeastern Virginia and the southern Delmarva Peninsula. Little, if any, of the snow will accumulate.

"The storm is expected to strengthen on Saturday night but should do far enough offshore for the Northeast to escape significant snowfall," AccuWeather Senior Meteorologist Kristina Pydynowski said. "At most, a bit of snow will graze the southern coast of New Jersey, the eastern tip of Long Island and Cape Cod, Massachusetts."

"Farther inland, snow showers and flurries not associated with the storm will stream downwind of the Great Lakes."

In the wake of the storm, chilly conditions are in store for the Midwest and Northeast on Sunday. While much of the Northeast will be dry and blustery, the next snow-maker will begin to spread over the Midwest.

"This storm is expected to spread a large swath of 3 to 6 inches of snow across the northern Plains but should fizzle to spottier snow and rain before reaching the Northeast," Pydynowski said.

"Only if the storm were to restrengthen along the coast would more substantial snow target the Northeast. However, odds are currently against this scenario unfolding."

Beyond early next week, temperatures are projected to ratchet upward to more seasonable levels.
