STORM DESCRIPTION
A low pressure system moving eastward across the Deep South brought another round of heavy snow and ice to most of New Jersey. Across much of northern and central New Jersey, this was the heaviest snowstorm of the winter.
Synoptic Discussion
The same slow moving frontal boundary which brought snow and ice to New Jersey on February 8th and 9th had pushed into the Deep South and over the northwestern Gulf of Mexico by early on the 10th. A low pressure system developed along the front over the northwestern Gulf during the day on the 10th and began moving northeastward. By early on the 11th, the low pressure entered Tennessee Valley. As it did so, energy began to transfer from the first low pressure to a new low pressure developing further east along the stalled front near the Outer Banks of North Carolina. This second low became the primary low by the evening of the 11th. By the morning of the 12th, the first low pressure had dissipated while the second low pressure had moved well east of the Mid-Atlantic Coast.
Local Discussion
Precipitation overspread the state from south to north during the night of February 10th. Across most of southern New Jersey, it began briefly as snow before quickly turning to sleet and freezing rain as warm air moved in aloft. Further north across central New Jersey, snow fell at a moderate to heavy rate through the morning of the 11th before changing to sleet during the afternoon. Across northern New Jersey, precipitation remained primarily in the form of snow, which also fell at a moderate to heavy rate during the morning hours before lessening in intensity somewhat during the afternoon. Precipitation tapered off from west to east during the evening of the 11th. Accumulations were highest across northeastern New Jersey where they ranged from 6 to 18 inches. Across northwestern New Jersey, accumulations averaged 4 to 12 inches, while across central New Jersey they averaged 5 to 10 inches. Across southern New Jersey, where more sleet fell than snow, total accumulations of both snow and sleet averaged from 1 to 4 inches. Ice accrual from freezing rain was rather light, with up to 1/4 inch across the far south.
