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.
