Snowfall Totals from January 30-31, 2000
STORM DESCRIPTION
A quick moving storm brought a burst of snow, sleet, freezing rain,
and/or rain to New Jersey.
Synoptic Discussion
A low pressure developed in the western Gulf of Mexico during the day
on the 28th. It moved slowly northeastwards, reaching
Apalachicola, Florida on the morning of the 30th. It then started
moving rapidly, quickly heading up the coast and reaching Boston,
Massachusetts on the morning of the 31st.
Local Discusion
The combination of a low track just inland of the coast, as well as
less cold air present initially, allowed for a more typical potpourri
of weather across New Jersey during this storm, with primarily rain in
far southeastern sections and primarily snow across far northwestern
sections. Precipitation overspread the state late in the
afternoon of the 30th. It began as snow in most areas, except the
far southeast and coastal sections, where enough warm air had moved in
from the ocean to allow precipitation to begin only briefly as sleet or
freezing rain before quickly changing to rain. By early evening,
precipitation had changed to sleet and freezing rain across
southwestern sections of the state, but west central and northern
sections remained all snow. By 9PM EST, enough warm air had made
it inland to change the precipitation in the southwestern sections over
to mainly rain, while the transition from snow to sleet and freezing
rain was occurring over the west central and northern sections.
By 10PM EST, sleet had made it as far north as Warren County, but the
cold air in Sussex County was too entrenched to allow it to continue
further northwards. The precipitation ended from south to north
across the state between midnight and 3AM EST on the 31st, while
temperatures in northwestern sections never made it above
freezing. Snowfall accumulations were greatest in the
northwestern sections due to the extended period of snowfall.
Snowfall totals reached 6 to 9 inches in Warren and Sussex counties, 3
to 6 inches in Hunterdon and Morris counties, 2 to 4 inches in Somerset
and Passaic counties, and 1 to 3 inches in Bergen, Hudson, Essex,
Union, Middlesex, and Mercer counties. Ice accretion was greatest
along the Delaware River townships between Salem and Mercer counties,
where ice accumulated to 1/4 inch thickness.
