Area Forecast Discussion
National Weather Service Mount Holly NJ
942 AM EDT Tue Oct 27 2020

.SYNOPSIS...
A weak front will continue to cross the area this morning before
moving to the south and weakening. Weak high pressure will build
over the area later today and remain into Wednesday. Low
pressure and the remnants of tropical system Zeta will move
across our area Thursday and Friday. High pressure will move in
for Saturday. Another front may affect the area Sunday.

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
A few light showers associated with the cold front moving
through the region, will gradually push towards the coast
through this morning. That front will move offshore prior to
lunchtime. The front then remains stationary south of the
region.

Behind the front, some drier air builds into the region. Skies
remain fairly cloudy for much of the day with occasional breaks
of sunshine through this afternoon. Surface dew points will
drop from the 50s/low 60s into the 40s by this afternoon.

The front begins to lift back north late in the day, and some
strong mid-level shortwave energy will pass through the southern
Poconos and far northwest New Jersey late. Will carry slight
chance PoPs for the northern half of the forecast area late in
the day.

Highs will top off in the 50s along and north of the Fall Line,
and in the low to mid 60s across southern New Jersey, the
Delaware Valley, and Delmarva.

Only minor adjustments to the forecast to better reflect
current observations and trends.
