STORM DESCRIPTION
A fast moving storm system from the southern Plains brought the heaviest snow of the season to much of southern New Jersey. Significant snow also fell in central and northern parts of the state.
Synoptic Discussion
An arctic high pressure settled over the Northeast late on Wednesday the 21st. At the same time, a low pressure system developed along the Red River Valley in the southern Plains. By Thursday morning the 22nd, it had moved eastward to northern Alabama. It then turned northeasterly, and began to push mild, moist air over the cold air mass already in place, resulting in widespread snowfall. The storm continued its was fast movement and was 300 miles east of the Delmarva Peninsula by the morning of Friday the 23rd, taking the snow and cold air with it.
Local Discussion
Snow began falling during the first half of the afternoon of the 22nd. Cold weather which had settled in on the previous day allowed the snow to accumulate quickly, and also produced very high snow-to-water ratios on the order of 20-to-1. The heaviest snow fell during the latter half of the afternoon and early part of the evening, when snowfall rates of 1 to 2 inches per hour were common. The snow tapered off from southwest to northeast around midnight EST on the 23rd. Snowfall totals were very similar across much of the state, ranging from 4 to 8 inches in most areas. The highest totals of around 8 inches were reported from Hunterdon county in west-central New Jersey and Atlantic County in southeastern New Jersey.
