Snowfall Totals from January 17-18, 1994
STORM DESCRIPTION
A complex storm system brought another round of snow, ice and rain to
New Jersey.
Synoptic Discussion
Two areas of low pressure connected by a cold front, one in central
Canada and the other near the Front Range of the Rockies, moved
southeastward during the day on the 16th. They both then turned
eastward during the day on the 17th, with the Canadian low passing just
north of the Great Lakes and the Front Range low passing just north of
the Gulf Coast. The southern low then raced northeastward on the
night of the 17th, reaching New England and merging with the northern
low after midnight. The combined low pressure system reached Nova
Scotia by midday on the 18th.
Local Discussion
Precipitation overspread New Jersey from west to east during the
morning of the 17th. In west-central and northern New Jersey,
precipitation began in the form of a heavy burst of snow. Across
east-central and southwestern New Jersey, it began in the form of sleet
and freezing rain, while across southeastern New Jersey, it began as
plain rain. A strong warm front then moved northwestward into the
state, causing warm air to move in both at the surface and aloft.
This caused the snow to change to sleet and freezing rain across
west-central and northeastern New Jersey by early afternoon on the
17th. Further warming caused the sleet and freezing rain to
change to rain across southwestern, central and northeastern New Jersey
by early evening on the 17th. However, precipitation remained
mainly in the form of snow and sleet across northwestern New Jersey,
and continued moderate to heavy at times. As the southern low
pressure system moved northeast across the state toward midnight on the
18th, cold air moved back across the state and the rain changed back to
snow before ending in most areas. Snow accumulations were
heaviest in the northwest, where 8 to 12 inches fell. Further
south and east, 2 to 6 inches fell across northeastern and west-central
New Jersey, with a coating to 2 inches across east-central and
southwestern New Jersey. Ice accretion was generally 1/4 to 1/2
inch, mainly across southwestern, central and northeastern New Jersey.
