Special Weather Statement, NWS Philadelphia/Mount Holly

Area Forecast Discussion
National Weather Service Mount Holly NJ
545 PM EDT FRI JUN 24 2016

.SYNOPSIS...
This weekend, a high pressure system will build over the region.
A frontal system will move through our area by mid week. A high
pressure system will build over our region later in the week.

&&

.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
The remaining showers and isolated thunderstorms in the western
and southern parts of our forecast area will dissipate during the
early evening hours with the loss of daytime heating.

The developing light northeasterly flow should bring dry air into
our region. However, we continue to think that low clouds and fog
will form tonight in areas that received heavy rainfall today.

Minimum temperatures should be mainly in the upper 50s and lower
60s.

&&

.SHORT TERM /6 AM SATURDAY MORNING THROUGH 6 PM SATURDAY/...
High pressure will continue to build in Saturday. There will
likely be some lingering clouds and fog, especially along the NJ
shore areas during the morning. After the mid-morning, mostly
Sunny skies are expected. Winds will continue to be from the E or
NE at 5 to 10 mph. High temperatures will reach into the low to
mid 80s in most areas.

&&

.LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/...
Saturday night: A clear night with light winds and conditions
favorable for radiational cooling. Some patchy fog is possible as
well just before sunrise when higher RH values correspond with the
light winds.

Sunday and Sunday night: High pressure will be moving eastward
and offshore resulting in another dry but hotter day. A look at
actual model data shows the ECMWF to be several degrees warmer
than the GFS. Boundary layer temperature output on both occasions
supports the model output. Given the dry conditions from
Philadelphia and points north this forecast and recent cool biases
with model data, this forecast is in line with the warmer ECMWF.
High temperatures will push the mid and upper 80's in most of the
region, with the highest readings in the Lehigh valley and the
cooler readings down by the shore. Southerly flow will result in a
warmer and muggy night as well Sunday night.

Monday through Wednesday: A cold frontal boundary will move from
the Great lakes southwestward through the region in this time
frame. A few mid-level shortwaves ahead of this front will likely
serve as triggers for scattered showers and thunderstorms in a
warm and humid air mass. The most likely window for rain based on
current ensemble data stretches from Monday night through Tuesday
night. However, given uncertainty in timing and coverage will
continue with chance pops. This will likely not dent the drought
across the northern half of the region. The actual cold front will
likely move through on Wednesday with a cooler and drier airmass
moving in behind the front. Winds will be southerly from 5 to 15
mph throughout the early part of the week.

Wednesday night through Friday: High pressure will build
southeastward into the region with a cooler and drier airmass.
Leaned at or warmer than ensemble guidance here given the dry
ground and recent temperature biases the past few weeks. Winds
generally westerly to southwesterly at around 10 mph.

&&

.AVIATION /22Z FRIDAY THROUGH WEDNESDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.

Tonight...The showers will diminish this evening then skies will
clearing from N to S. We will likely hold onto some low clouds
across the srn areas. Any breaks will result in fog development
across the srn areas. Low clouds could affect KPHL/KPNE and up
into KTTN also. We have decided to preserve some of the earlier
clouds in the fcst. The guidance doesn't mention much in the way
of low clouds, but the pattern seems to favor it. Winds tonight
light from the NE or E.

Sat...VFR conditions expected after any low clouds or morning fog
dissipates. Winds will be east at around 10 knots by early
afternoon.

Outlook...
Sunday and Sunday night: VFR. Southwest winds around 10 knots.

Monday through Tuesday night: Mainly VFR. Some scattered
thunderstorms will reduce vsbys and ceilings to MVFR and IFR at
times. The highest chances for any storms are on Tuesday.
Southwest winds from 5 to 15 knots, highest Monday and Tuesday
afternoon.

Wednesday: VFR. Northwest winds around 10 knots.

&&

.MARINE...
Onshore flow will continue tonight and Saturday with high
pressure building in from the north. Scattered thunderstorms
across the srn NJ and DE waters this afternoon will diminish this
evening. patchy fog is possible tonight. Seas have been steady
around 3-4 ft so far today and this will continue tonight. Seas
will tick up closer to SCA criteria seas Saturday. Confid is still
not the greatest however, we'll just mention 4 ft seas attm and
hold on the SCA flag for now. Fair weather expected Saturday.

Outlook...
Saturday night through Wednesday:

Seas will remain under five feet throughout the period. The
highest seas around four feet are likely to occur into Sunday then
again on Tuesday. Top wind gusts will top out around 20 knots both
Monday and Tuesday afternoons from the south.

RIP CURRENTS...
Moderate risk for rip currents the rest of today and probably Sat
also. High pressure will bring lighter winds and lowering seas
Sun. Risk on Sun will likely be less than Sat.

&&

.PHI WATCHES/WARNINGS/ADVISORIES...
PA...None.
NJ...None.
DE...None.
MD...None.
