Area Forecast Discussion
National Weather Service Mount Holly NJ
402 PM EDT Fri Jul 16 2021
.SYNOPSIS...
High pressure located over the western North Atlantic will lose
its influence over our weather gradually through Saturday. A cold
front approaching from the northwest is forecast to arrive on Sunday.
The boundary is expected to stall and slowly dissipate in or near
our region early new week. Another cold front is anticipated to
reach eastern Pennsylvania, New Jersey, eastern Maryland and Delaware
around Wednesday night.
&&
.NEAR TERM /THROUGH SATURDAY NIGHT/...
Isolated diurnal convection will continue into the early evening
hours, mainly in our counties along and to the north of the
Interstate 78 Corridor. With the loss of daytime heating, the
isolated showers and thunderstorms should dissipate.
A mid level disturbance is forecast to pass over eastern
Pennsylvania, and northern and central New Jersey overnight. It will
bring another chance of scattered showers and isolated thunderstorms
to those areas mainly between about 11:00 pm and 5:00 am.
Saturday morning and early Saturday afternoon should be rain-free
with just some scattered cloud cover.
The lee-side surface trough is expected to become better defined on
Saturday. Also, some mid level energy will begin to approach from
the west. Showers and thunderstorms will move into our region from
that direction during the mid to late afternoon hours. The area of
convection is anticipated to work its way across eastern
Pennsylvania, eastern Maryland, Delaware and New Jersey slowly, not
fully moving off the coast until late Saturday night.
Precipitable water values are expected to rise into the 2.0 to 2.3
inch range. As a result, locally heavy rain is likely. In light of
the recent wet conditions, we have issued a Flash Flood Watch for
our counties in eastern Pennsylvania, northern Delaware, and New
Jersey (except the far south).
Mixed layer CAPE values are forecast to be 2000 to 2500 J/kg in
parts of our region on Saturday afternoon. With moderate shear,
there is the potential for locally strong wind gusts with any
thunderstorms that develop.
In regard to the heat, temperature and humidity levels on Saturday
should be similar to those of today, so we will keep the Heat
Advisory in place, and extend it for Morris, Monmouth, Ocean and
southeastern Burlington until 8:00 PM Saturday.
&&
.SHORT TERM /SUNDAY THROUGH SUNDAY NIGHT/...
The front will continue to slowly cross the area. Clouds and
showers/tstms will be numerous for the first parts of the day into
the afternoon, before tapering off from NW to SE. Humidity
levels will still be high, but will fall off later on as some
drier air from the N works its way into the area. Highs Sunday
will be in the upper 70s/low 80s N/W and mostly mid 80s for
Philadelphia and Delmarva.
&&
.LONG TERM /MONDAY THROUGH FRIDAY/...
Mon thru Wed...Unsettled conditions will continue into next
week as the upper H5 trough continues nearby being recharged by
several short wave disturbances moving in to reinforce it. We
will feature mostly chc pops for Mon and Wed and mostly slight
chc pops for Tue. Highs Monday will be a few degrees below
normal, but Tue/Wed will be back near normal with highs mostly
in the mid 80s.
Wed night thru Fri...Better conditions with weak ridging
building across the area. A few of the longer range models
indicate another disturbance may arrive Fri. but now now we
will leave the mention of Pops out of the fcst with the
uncertainty being rather high. Highs will be mostly close to
normal for mid July.
&&
.AVIATION /20Z FRIDAY THROUGH WEDNESDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY and surrounding areas.
Into this evening...Mainly VFR with isolated showers and
thunderstorms. Southwest wind 5 to 10 knots. High confidence.
Overnight...Mainly VFR. However, scattered showers and thunderstorms
may bring MVFR conditions to KRDG, KABE, KTTN and vicinity between
03Z and 09Z. Variable wind 5 knots or less. Medium confidence.
Saturday...Mainly VFR through 18Z, then deteriorating conditions as
showers and thunderstorms arrive from the west. Southwest wind
increasing to around 10 knots with gusts of 15 to 20 knots. Medium
confidence.
Outlook...
Sat night...Widespread lower CIGS/VSBYS with showers and tstms.
Sun thru Wed...Mostly VFR. Scattered showers and tstms with
lower CIGS/VSBYS mostly during the afternoon and evening hours.
Patchy fog possible late at night through dawn.
&&
.MARINE...
A south to southwest wind 10 to 15 knots is expected for much of the
time through Saturday night. Wave heights on our ocean waters are
forecast to range from 2 to 4 feet, with waves on Delaware Bay at 2
feet or less. Showers and thunderstorms are likely from late
Saturday afternoon into Saturday night.
Outlook...
Mostly sub-SCA. Scattered showers and tstms with localized
higher winds and seas each day.
Rip currents...
A relatively light southwest to south flow is expected through
Saturday with wind speeds around 15 MPH or less. Breaking waves
are forecast to be 1 to 2 feet with a medium period southerly
swell. As a result, the rip current risk is LOW through Saturday.
