Contoured Snowfall Totals from February 15-16, 2010

STORM DESCRIPTION
A strengthening storm from the Midwest brought light snow to most of New Jersey, with heavier snow over the northeastern corner of the state.

Synoptic Discussion
Low presssure moved southeastward from Canada into Montana during the day on February 12th. By the morning of the 13th it had moved into the Dakotas, and by the evening of the 13th it was near Omaha, Nebraska. It had moved into Missouri by the morning of the 14th, and reached the lower Ohio Valley by the evening of the 14th. By the morning of the 15th it was near Cincinatti, Ohio, and moved into western Pennsylvania by the evening of the 15th. From here, a secondary low pressure developed closer to the coast in eastern Virginia, which became the primary low pressure as it moved to a position just south of Long Island on the morning of the 16th. It was near Cape Cod by the evening of the 16th, and moved to a position just east of Nova Scotia by the morning of the 17th.

Local Discussion
An initial burst of precipitation associated with the surface features of this system overspread New Jersey during the early evening hours of February 15th. Precipitation was mainly in the form of snow in central and northern New Jersey, but mixed with sleet and freezing rain across interior southern New Jersey, and was mainly in the form of rain across coastal southern New Jersey. Precipitation lingered until just after midnight on the 16th, at which point it ended from southwest to northeast across the state. A second period of precipitation associated with the upper level low pressure moved into the state just after dawn on the 16th. This second batch of precipitation was accompanied by colder air and was therefore in the form of snow statewide. This second period of snow ended from southwest to northeast during the early and mid afternoon. Snowfall accumulations were highest in northeastern New Jersey and much lighter elsewhere. Totals ranged from 3 to 10 inches in Passaic County, 2 to 8 inches in Bergen, Morris and Sussex counties, 1 to 6 inches in Essex, Hudson and Warren counties, 1 to 4 inches in Middlesex and Union counties, 1 to 3 inches in Gloucester, Hunterdon, Mercer, Monmouth and Somerset counties and a coating to 2 inches in Atlantic, Burlington, Camden, Cape May, Cumberland, Ocean and Salem counties.
