Snowfall Totals from April 09, 2000
STORM DESCRIPTION
A strong Spring cold front and developing wave of low pressure combined
to produce a sudden Spring snow fall across most of New Jersey.
Synoptic Discussion
A strong cold front passed over the East Coast on the evening of the
8th. A strong secondary low formed on the frontal boundary in the
Mid Atlantic overnight, and by 8AM EDT on the 9th it had moved north to
Worcester, Massachusetts. As the low quickly intensified, it
produced a large shield of precipitation behind the cold front, while
at the same time pulled the colder air in behind it more quickly with
very strong northwest winds. By the evening of the 9th, the low
and associated precipitation had pulled northeastward into Canada.
Local Discusion
The strong cold front passed through New Jersey on the evening of the
8th between 6PM and 8PM EDT. A squall line just ahead of the
front had weakened as it approached the coast and interacted with more
stable marine air over the ocean, and as it crossed New Jersey the line
only produced some light rain showers. Temperatures fell quickly
as the front passed, from the upper 60s and lower 70s down to the mid
50s in just an hour's time. Temperatures continued to fall
straight through into the mid morning of the 9th. Post-frontal
precipitation associated with the developing secondary low moved into
the state as rain between 10PM EDT on the 8th and 2AM EDT on the
9th. As temperatures continued to fall, the rain changed to snow
from north to south across western New Jersey, but then southwest to
northeast across eastern New Jersey. The change to snow occured
around 1AM EDT on the 9th in Sussex County, and proceeded south to
Cumberland County by 5AM EDT. It then worked its way back to the
northeastern sections, reaching Teterboro by 9AM EDT. The snow
became heavy at times for a few hours during the morning of the 9th in
many locations. Snow tapered off from southwest to northeast
between 10AM EDT and 2PM EDT on the 9th. Accumulations were
greatest in the northwestern counties where the changeover had occured
earliest and precipitation had fallen for the longest time as
snow. 4 to 8 inches fell in Sussex and Warren counties, 2 to 6
inches in Passaic and Morris counties, 3 to 5 inches in Huterdon,
Somerset, and Mercer counties, 2 to 4 inches in Middlesex, Monmouth and
Burlington counties, and a coating to 3 inches in Camden, Gloucester,
Ocean, Union, Essex, Hudson, and Bergen counties. Only a dusting
to an inch accumulated in the southern coastal counties of Salem,
Cumberland, Cape May, and Atlantic. Winds with this system were
also very strong, reaching peak gusts of 65 mph in Harvey Cedars on the
coast, and 67 mph at High Point in the far northwest.
