New York City and the U.S. Northeast may get some snow later this week from a storm that will develop off the East Coast.
The exact amount of precipitation will depend on the track the storm takes and how fast it grows as a second system weakens over the Great Lakes, said Dan Hoffman, a National Weather Service meteorologist in Upton, New York. It should arrive late on Feb. 7 and end sometime before daybreak on Feb. 9.
“New York City itself, the five boroughs, definitely bears the potential of seeing an accumulating snow fall at the end of this week,” Hoffman said by telephone. “Some forecast models, the vast majority of them, started hinting at a significant coastal storm later this week.”
The weather service has issued a hazardous weather outlook for the coast from Delaware to Massachusetts warning of flooding and heavy rain and snow. While snowfall accumulations aren’t posted yet for New York and areas south of the city, residents in Massachusetts are being warned as much as 12 inches (30 centimeters) may fall in some places.
As of Feb. 4, 7 inches of snow has fallen in New York’s Central Park or about 6.4 inches less than normal, according to the weather service. Boston is also lagging behind its seasonal pace for snow, receiving 9 inches since Dec. 1, or about 14.5 inches less than normal.
The Great Lakes storm is a factor for the snowfall amount because if that system falls apart quickly more cold air will be available to a nor’easter coming up the coast, said Hoffman. It could mean the difference between a few extra hours of snow versus rain in some areas along the shoreline, he said.
The weather service will have a better estimate of how much snow will fall as the week progresses, Hoffman said. The weather service forecasts a 60 percent chance of snow on Feb. 7 and a 70 percent chance of rain or snow on Feb. 8 in New York City.
Boston has a 90 percent chance of snow and Philadelphia has a 70 percent chance of rain on Feb. 8, according to the weather service.
