Area Forecast Discussion
National Weather Service Mount Holly NJ
916 AM EDT Sun May 18 2025

.SYNOPSIS...
A reinforcing cold front will cross through the area tonight.
High pressure will return for Monday and Tuesday. Another
dynamic weather system will approach the region towards the
middle of the week, bringing another period of unsettled weather
through the end of the week.

&&

.NEAR TERM /THROUGH TONIGHT/...
Low pressure will gradually continue to shift east through the
day today across Maine and into the Canadian Maritimes tonight.
A secondary cold front will traverse through early this evening
as cool Canadian high pressure noses in from the north and west.

All things considered, dry and seasonable weather is expected though
tonight. Skies will be partly cloudy this morning but will feature
more clouds than sun this afternoon. Perhaps a rouge shower may
occur late in the afternoon up in the Poconos, but in all likelihood
the potential for this is very low. The one thing of note is that
winds will increase today as diurnal mixing occurs with the area
remaining wedged between systems. Forecast soundings suggest the
boundary layer will mix out pretty well this afternoon, so its
likely we`ll see some higher winds aloft mix down. So, wind gusts
up to 40 mph seem plausible with highs mostly in the 70s (60s in
the Poconos). The secondary cold front will cross through this
evening dry, with the only notable change behind this front will
be dew points falling from the 50s into the 40s. Skies will
become mostly clear tonight behind this front as temperatures
fall into the 40s/50s. Winds will diminish as well but gusts
upwards of 20 mph may still be possible overnight.

&&

.SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/...
Upper level ridging pattern will keep mostly clear skies and dry
conditions across the region through Tuesday. There will be a breezy
northwest flow with gusts up to 30 mph on Monday with high pressure
ridging in from Canada creating a tight pressure gradient with our
departing upper low moving offshore of New England. Winds diminish
Monday night and into Tuesday. Daytime highs will be in 70s on
Monday with a mix of 60s/70s on Tuesday. Lows will be in the 40s/50s
at night. Increasing clouds expected Tuesday night as our next
system approaches. Chances for rain do begin to increase west to
east late Tuesday night and into the early morning hours
Wednesday.

&&

.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
Our attention turns to our next weather system which will take aim
at the area beginning midweek. A deep upper trough is expected to
close off over the northern Great Lakes region on Wednesday. This
feature is then forecast to gain a negative tilt as a vigorous piece
of energy rounds the base of the trough Wednesday night into
Thursday. The upper low will then meander over the Northeast US
through Friday.

Global and ensemble guidance continues to develop an area of low
pressure at the surface over the Ohio Valley while tracking up into
the eastern Great Lakes on Wednesday. As it does so, a secondary
coastal low will develop off the Mid-Atlantic coast by Wednesday
night while deepening as it moves up into New England on Thursday.
These features support another period of active and unsettled
weather with periods of rain with the heaviest rain still expected
Wednesday and Thursday. POPs for this timeframe are now up to 70-
90%, tapering off later on Thursday. Shower chances decrease a bit
Thursday night, but still remain around 30-50% as the area remains
situated under the upper trough. As the main surface low departs
Friday and Saturday, the chance for widespread heavy rainfall will
diminish, but due to the influence of the upper low lingering around
the Northeast, there remains a 20-40% chance for showers during this
time. Below normal temperatures are expected throughout the period
with gradual warming by Saturday.
