Storm Expected to Bring Snow to Northeast and Mid-Atlantic, Again

A fast-moving storm system was expected to bring several inches of snow to parts of the Northeast and Mid-Atlantic regions for the second time this week, with two to four inches predicted for New York City overnight Friday into Saturday morning and up to 10 inches in portions of West Virginia and Maryland.

Dominic Ramunni, a meteorologist with the National Weather Service in New York, described the system that was expected to move through as a “quick hitter.”

“It’ll be in and out before folks may even wake up tomorrow morning,” Mr. Ramunni said.

The greatest snowfall totals were expected across parts of Virginia, West Virginia, Maryland and southern Pennsylvania, where a winter storm warning was issued for late Friday through Saturday morning, according to the National Weather Service.

In parts of Maryland and West Virginia, up to 10 inches of snow were possible, with snowfall rates of up to two inches per hour at times, the Weather Service said.

Austin Mansfield, a meteorologist with the National Weather Service office in Sterling, Va., said the snow could make travel difficult at times and reduce visibility.

“Anytime you have a significant accumulation like that, you certainly start to see road impacts across those areas,” he said.

Philadelphia could record four to six inches of snow, and Washington could see snowfall totals ranging from two to five inches, forecasters said.

In New York City, where snow from a storm on Tuesday was still melting on Friday afternoon in parts of the area, there could be snowfall totals from two to four inches, Mr. Ramunni said.

The storm system is expected to bring snow to some Northeast cities for the second time this week.

A storm that moved through the region on Tuesday dropped 3.2 inches in Central Park and more than eight inches of snow in parts of Maryland, according to the Weather Service.

Ahead of the expected weekend snowfall, the New York City Emergency Management Department issued a citywide travel advisory, warning that slippery roadways and reduced visibility were possible late Friday through early Saturday.

Temperatures overnight Friday into Saturday were expected to be lower than during Tuesday’s storm, indicating that New York City could get a more powdery snow.

“We’re not expecting that really heavy wet snow that we saw with this last event,” Mr. Ramunni said. “You’re not shoveling bricks of cement, so to speak, tomorrow morning.”

Snow has been something of a rarity in New York City over the past couple of years. After 701 days without meaningful accumulation, a total of 1.7 inches fell in Central Park on Jan. 15 and Jan. 16.

If more than 3.2 inches are recorded in Central Park on Saturday, it would be the city’s highest snowfall in two years, Mr. Ramunni said.

“As a snow lover,” he said, “my tail’s wagging.”
