Contoured Snowfall Totals from January 20-21, 2000

STORM DESCRIPTION
The first widespread accumulating snowfall of the 1999-2000 winter season brought 1 to 6 inches of snow to New Jersey.

Synoptic Discussion
A pair of low pressure systems, one that moved from the northern plains into western Pennsylvnaia before dissipating later on the 20th, and a secondary that developed just southwest of the Outer Banks of North Carolina on the morning of the 20th, were the cause of the snowfall.  The remaining secondary low intensified but moved offshore to the east-northeast relatively quickly.  This prevented more substantial accumulations from occuring and also prevented heavy snow from moving further northwest into the state.

Local Discusion
Snow spread across the state between 5AM and 8AM EST on the morning of the 20th and fell at a steady rate throughout the day.  The snow was heaviest in the southeast sections of the state, but was lighter elsewhere.  Accumulating snow ended from northwest to southeast during the evening, but lingered until after midnight along the southeast coast.  Light snow showers and flurries also lingered across the state until after midnight, but produced no additional accumulations.  Accumulations were generally 3 to 6 inches southest of the New Jersey Turnpike, and 1 to 3 inches northwest of it.
