...FREEZING DRIZZLE IN THE HIGHEST ELEVATIONS THROUGH EARLY THIS
EVENING...

Freezing drizzle is possible along the ridges, for elevations
above 1000 ft, through early this evening across far northwestern
New Jersey and the Southern Poconos. In these locations, a light
glaze of ice is possible on elevated surfaces and untreated roads.
Some locations that could be affected include Wantage, High Point,
and Mount Pocono.

Temperatures are expected to gradually increase over the next few
hours, so the precipitation should change over to drizzle or rain
by early this evening.
