Snowfall Totals from January 19-20, 2002
STORM DESCRIPTION
A weak low pressure passing through the Southeastern states brought the
only widespread snowfall of the winter to New Jersey.
Synoptic Discussion
The low pressure developed over the western Gulf Coast during the
evening of the 18th. By the morning of the 19th, the low had
moved northeastward into northern Mississippi. By noon the low
had moved into Tennessee as a second low developed on the North
Carolina coast. This second low moved northeastward off the
Virginia coast on the evening of the 19th as the original low
dissipated over the southern Appalachians. The newer low pressure
was well off the coast of New Jersey by the morning of the 20th.
Local Discussion
Snow begain falling across southern parts of the state on the morning
of the 19th, while it held off until the early afternoon across
northern portions of the state. The snow became steady and was
occasionally moderate to heavy. The snow changed to sleet and
rain by mid afternoon in southeastern sections of the state.
Further northwest, the snow changed to sleet and freezing rain close to
sunset across east-central and southwestern New Jersey. The rain,
freezing rain and sleet changed back to snow in all areas for a few
hours before precipitation ended across the state around
midnight. Snowfall accumulations ranged from 3 to 6 inches across
Sussex, Warren, Morris, Passaic, Bergen, Hudson, Essex, Union,
Somerset, Hunterdon, and Mercer counties where precipitation remained
all snow; generally 2 to 4 inches in Salem,Gloucester, Camden,
Burlington, Monmouth and MIddlesex counties where the snow changed to
sleet and freezing rain for a time; and 1 to 3 inches in Atlantic,
Cumberland, Cape May and Ocean counties where the snow changed to all
rain for much of the afternoon of the 19th.
