A low pressure system rapidly intensified and moved north along the mid Atlantic coast during Saturday December 30th. This produced a wide swath of heavy snow to the northwest of the storm track. Snowfall began between 5 and 7 AM across the area, and fell at intense rates right from the start. Snowfall rates of one to two inches per hour were common. There were also numerous reports of thunder and lightning accompanying the most intense snow bands. Winds also began to increase later Saturday morning, causing some blowing and drifting of snow, which reduced visibilities significantly, and created near blizzard conditions at times in some areas. As the low pressure center approached the south shore of Suffolk county early Saturday afternoon, milder air from the Atlantic Ocean wrapped into the storm system, and changed the heavy snow to a mixture of sleet and rain across eastern Suffolk county. This limited snowfall amounts somewhat across eastern Suffolk County.The low pressure center crossed central Suffolk County during mid afternoon on Saturday, before moving northeast into southern New England later that evening. As the low moved away, the precipitation tapered off across the area. Subfreezing temperatures and gusty winds lingered behind the storm system.Here are some specific snowfall totals from this storm system:Orange County: 14 inches at Harriman, to 21 inches at Warwick and Rock Tavern.Putnam County: 13 inches at Carmel and Brewster.Rockland County: 15 inches at Airmont, to 18 inches at Suffern.Westchester County: 13 inches at Mount Kisco, to 16.5 inches at Mamaroneck.Bronx County: 11 inches.New York County (Manhattan): 12 inches at Central Park.Kings County: 12.7 inches at Gravesend.Queens County: 10 inches at John F. Kennedy International Airport, to 13 inches at LaGuardia Airport and Middle Village.Richmond County: 12.5 inches at Grymes Hill.Nassau County: 11 inches at Lynbrook, to 15.6 inches at Oceanside.Suffolk County: 2.7 inches at Bridgehampton, to 12 inches at Huntington Station, East Northport, and North Lindenhurst.
