AREA FORECAST DISCUSSION
National Weather Service Mount Holly NJ
923 PM EDT Sat Apr 4 2020
Weather Synopsis:
A weak ridge of high pressure will build over the area tonight and
remain into Sunday. A weak cold front will cross the area Sunday
afternoon and evening. More high pressure returns for Monday. A
disturbance will bring unsettled conditions for the middle the
upcoming week. Another low and its fronts will arrive for Friday and
remain nearby into next weekend.
Near Term:
UNTIL 6 AM SUNDAY MORNING -
Our area is embedded within weak flow in between the departing
low pressure over the ocean and a cold front moving through the
Great Lakes and Mid-West region. Weak high pressure is likely to
develop just to our south, with a weak surface trough to our
north. There will remain plenty of low level moisture moving across
the area overnight, so there will remain periods of cloudy
conditions through the overnight hours. Later in the night, a
weak short wave/vorticity impulse will move across the area from
the northwest withing the northwest flow aloft, so a few showers
may be possible across portions of northern New Jersey and
northeast Pennsylvania. Any precipitation will be light.
Short Term:
6 AM SUNDAY MORNING THROUGH 6 PM SUNDAY -
Overall, another fairly quiet day on tap weatherwise. A weak cold
front will continue to slowly approach from the north but ahead of
it the W/SW flow will result in milder temperatures. There will also
continue to be a fair amount of cloud cover but there should be at
least a little more sunshine compared to today. Generally expect
highs in the mid 60s except upper 50s to low 50s over NE PA into NW
NJ. Most of the day should be dry but by late day there could be
some isolated showers moving into eastern PA ahead of the
aformentioned front.
Long Term:
SUNDAY NIGHT THROUGH SATURDAY -
Sunday night thru Monday night...A mostly dry period, especially
Monday which looks like a nice day with high pressure building
overhead. Isolated showers may arrive Monday night as a warm
front begins to push towards the area from the Ohio valley. I
put just a slight chc for a shower at this point. The milder
temperatures that arrive for late this weekend will continue
into next week with readings 5 to 10 degrees above normal.
Tue thru Wed...A deepening upper trough across the northern Rockies
and Plains states will stir up a sfc cyclone across the Great Lakes
region Tue which will head east across New England into Wed. This
will bring scattered to occasional showers to the area Tue thru Wed,
with the cold front expected to cross the area Wed afternoon, a few
tstms are also possible since a mild and humid airmass will be in
place. Highs and lows will remain generally 5 to 10 degrees above
normal. Highs will be in the upper 60s to low 70s for Delmarva and
low to mid 60s
Wed night and beyond...Mostly unsettled with the upper trough deepening
across the Great Lakes and then swinging across the Northeast late
week. Another low pressure system will spin up across Canada Thu
and send a stronger cold front across the Middle Atlantic
towards the end of the week. There will be some chc for showers
Thu thru Sat with the greatest chc for Thu. Uncertainty builds
during the end of the week with some of the models slower with
the system. Temperatures will drop back to normal Fri and then
remain either normal or below into next weekend. Some higher
elevation snow showers are possible next weekend.
