AREA FORECAST DISCUSSION
National Weather Service Mount Holly NJ
351 AM EDT Wed Apr 2 2025
Weather Synopsis:
Cool and dry high pressure will remain in control through
today. A warm front will lift north across the area tonight as a
strong low tracks through Quebec on Thursday. The front will
return on Friday as a cold front, slowly dropping south of the
area by Friday night. Several waves of low pressure will ride
along this boundary causing it to fluctuate north and south
through the weekend yielding unsettled weather conditions. Cool
and dry high pressure will return by early next week.
Near Term:
THROUGH TONIGHT -
Cooler and dry conditions will continue through today.
Increasing clouds through the day, along with a strengthening
southeasterly breeze. A few showers possible this evening and
tonight, but largely dry for most areas along with more mild
temperatures.
Upper ridging will return today into tonight. At the surface,
cold and dry Canadian high pressure will depart as the day
progresses. A warm front will return north through the area
overnight.
The modified Canadian airmass from the departing high pressure
will be advecting in off the cold ocean today with a southeast
breeze increasing to 10-15 mph by this afternoon, with gusts up
to 25 mph. This pattern won`t bring any surface "warm"
advection to our area during the day despite upper level warm
advection beginning, so temperatures will actually end up being
near to a few degrees cooler than Tuesday in most areas.
Increasing clouds throughout the day won`t help either. Low
level warm advection won`t really begin until late afternoon or
evening, when the warm front will finally start lifting north
through the area as winds shift more southerly overnight.
Highs today are mainly in the upper 40s to mid 50s. Closer to
60 degrees for interior Delmarva. Temperatures won`t fall much
this evening given the considerable cloudiness and winds
(evening lows mainly in the 40s to near 50 degrees), and will
start rising into the 50s after midnight in most areas.
A few showers and isolated thunderstorms possible this evening,
and again after midnight. The potential evening activity will be
associated with the initial warm advection ramping up, but this
will be isolated to scattered in nature at most and
insignificant with regards to any measurable rainfall. Late
tonight and toward dawn Thursday, it appears chances are
increasing for remnant upstream convection from the southern
Great Lakes and Ohio Valley will reach our region. Obviously a
lot of uncertainty with this, as it will be dependent on
convective evolution upstream. Long story short, PoPs were
increased late in the night and early Thursday morning. No
hazards are anticipated with this activity, mainly just rumbles
of thunder and brief heavy downpours possible.
Short Term:
THURSDAY THROUGH FRIDAY NIGHT -
Warm front will be slowly lifting northward across the region
at the start of Thursday, so while the day likely starts off wet
and murky, expect some rapid afternoon improvements, perhaps
not at all unlike what we saw Monday, with temps soaring back
into the 70s with some spots possibly touching 80. This will set
the stage for another round of showers and thunderstorms late
in the day into the evening as a wave passes to the north and
drags a cold front back into the region, but right forcing and
instability don`t look especially great so only a marginal risk
is outlooked for the region. Lows Thursday night should range
from the 40s Poconos to the 60s Delmarva. The front slips back
to the south on Friday, with cooling temps and showers gradually
ending. Highs Friday will be mostly in the 60s as cooler air
drains back south into the region. We`ll start out mainly dry
Friday evening as high pressure from the north briefly pushes
in, but by late Friday night. Lows will range from the 40s north
to 50s south.
Long Term:
SATURDAY THROUGH TUESDAY -
Wave of low pressure passes mostly to the north Saturday, but
the stalled front to the south will be hard to budge, so
expecting highs in the 50s north, 60s south with some rain and
drizzle at times, especially in the morning. Warm front should
make better progress Saturday night as another, stronger low
approaches from the west, with lows 40s north ranging to 60s
south. Sunday looks like another day like Monday/Thursday with
warm air surging northward ahead of the aforementioned next
system. Another severe weather opportunity, though right now
dynamics and instability again don`t look too great, so not
highlighting it much yet. Should manage the 70s for most of the
region again. Bottom then drops out behind that system as that
cold front brings a surge of cooler air, followed by a
secondary surge of arctic air for Tuesday, resulting highs
struggling to reach 60 Monday and struggling to reach 50 on
Tuesday, with widespread freezing conditions possible by Tuesday
night. Any chance of precip looks to end with the first front
pushing southeast of the area by midday Monday.
