Contoured Snowfall Totals from February 21-22, 2011

STORM DESCRIPTION A weak wave of low pressure brought one more round of snow to central and southern New Jersey. Synoptic Discussion The surface low ultimately responsible for this snowstorm came ashore in California during the evening of February 18th. By the morning of the 19th the low had moved into the Great Basin of Nevada and by the evening of the 19th it had moved across much of Utah. Early on the 20th the low pressure was located in eastern Colorado and by that evening it had moved across Nebraska and into Iowa. By the morning of the 21st the low had entered Illinois, and by the evening that day it had entered northern Kentucky. By the early morning of the 22nd the system had dropped southeastward into North Carolina, and by the evening of the 22nd the low was pushing south into southern South Carolina. By the morning of the 23rd it was east of northern Florida. Local Discussion Snow overspread much of southern New Jersey during the evening hours of the 21st, but had great difficulty pushing further north due to a very cold and dry high pressure system located in southern Canada. While snow fell heavy at times in parts of southern New Jersey during the late evening and early overnight hours, only light fell snow in central New Jersey with no snow at all in much of northern New Jersey. The snow departed the state from northwest to southeast before dawn on the 22nd. Snowfall accumulations were greatest in southern New Jersey, with totals ranging from 2 to 6 inches in Atlantic, Burlington, Camden, Cape May, Cumberland and Salem counties, a coating to 4 inches in Ocean County, a coating to 1 inch in Mercer and Monmouth counties, a trace to a coating in Hunterdon, Middlesex, Monmouth, Somerset and Warren counties, and a trace or less further north and east.
