Area Forecast Discussion
National Weather Service Mount Holly NJ
914 PM EDT Sun May 27 2018
.SYNOPSIS...
Cold front has pushed south of the area, and will become nearly
stationary over the Mid- Atlantic and stretching back to the
south and west for much of the new week. Weak low pressure
passes through the region tonight. High pressure begins to build
in from the north on Monday, and then will push a back door
cold front through the region late Tuesday as the high settles
over Cape Cod on Wednesday. Meanwhile, what is currently
Subtropical Storm Alberto will lift north and push the
stationary boundary north as a warm front on Thursday. These
remnants look to affect the Northeast and Mid-Atlantic for the
end of the week and through next weekend.
&&
.NEAR TERM /UNTIL 6 AM MONDAY MORNING/...
The back door cold front has pushed through our entire area now
that it has pushed south of Delaware. Most of the heaviest
showers and thunderstorms have pushed across far southern
Delaware and just south. However, there remains the chance for
some heavy rain across far southern Delaware and the eastern
shore of Maryland as additional short wave/vorticity impulses
will interact with the warm/tropical airmass overriding the
front to our south. For areas farther north, there will remain a
chance of showers this evening, but they are not expected to be
as heavy as points farther south. The Flash Flood Watch has
been cancelled for much of the area except far southern Delaware
and southern portions of the eastern shore of Maryland.
Once the showers taper off, areas of fog and drizzle will likely
develop across much of the area where it hasn't formed already.
Areas across northeast Pennsylvania and northern and central
New Jersey have already experienced some drizzle this evening
and will likely to continue to have some overnight. The fog is
not expected to become dense, except the far northern areas in
the highest elevations like the Poconos.
Winds out of the east to northeast may gust up to around 20 mph
this evening, and up to 30 mph closer to the coast.
&&
.SHORT TERM /6 AM MONDAY MORNING THROUGH 6 PM MONDAY/...
With the front nearby and residual onshore flow, areas of
drizzle and patchy fog may linger through mid-morning under
mostly cloudy skies. A few lingering showers are possible across
Delmarva and far southern NJ during the early morning. A weak
flow in place at the low-levels will lock in the clouds during
the morning, but some subsidence will work in during the
afternoon, especially northwest of the fall-line. Expect some
breaks to develop in the overcast across this area, especially
during the afternoon. High temps will be slightly below seasonal
norms. Winds will be light and variable.
&&
.LONG TERM /MONDAY NIGHT THROUGH SUNDAY/...
A prolonged period of unsettled weather is on tap for much of
the long term. This includes potential impacts from the remnant
low of what is currently Subtropical Storm Alberto late this
week and through next weekend.
A warm and soupy airmass will be in place Monday night. Can
expect warm and humid conditions as southwest flow ushers a
tropical airmass into the region that will be in place through
the week. Stationary boundary remains south of the Delmarva, and
weak low pressure passing along that boundary may result in a
few showers in the evening, but precip will end by midnight or
so. Patchy fog should develop.
High pressure over central Canada builds to the south and east
on Tuesday, will pass north of New York state Tuesday night, and
then will park itself over Cape Cod on Wednesday. This will
allow a back door cold front to drop through the region Tuesday
night. Meanwhile, the remnant low of Subtropical Storm Alberto
lifts north through the Tennessee Valley and into the southern
Great Lakes and Ohio Valley. This pushes the stationary boundary
north as a warm front Tuesday night.
The warmest day of the period looks to be Tuesday, as very warm
and humid conditions on tap with highs in the mid and upper 80s
and surface dewpoints well in the 60s. This will yield a heat
index around 90 for most inland locations. A few showers and
thunderstorms are possible Tuesday afternoon and evening as that
warm front lifts north, mainly over western zones.
From there, unsettled weather possible each day depending on
the track and placement of the remnant low of Alberto. The low
lifts through the Great Lakes and tracks into eastern Canada
Thursday and Friday before dropping back into the Northeast and
Mid-Atlantic over the weekend. Best chances for precip currently
look to be Thursday, but will carry at least chance PoPs into
the weekend. With low agreement among the global models, feel it
is best to keep with chance PoPs for now. But it is important
to note that there will be a tropical airmass in place with
surface dewpoints well in the 60s to near 70 ahead of the
remnants of Alberto, and given the tropical origins of Alberto,
there could be a prolonged period of heavy rain next weekend.
&&
.AVIATION /01Z MONDAY THROUGH FRIDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.
Tonight...Low end MVFR or IFR conditions remain across the area
this evening, and all sites are expected to lower to IFR through
the remainder of the evening and overnight. There will remain
showers across southeastern Pennsylvania, central and southern
New Jersey, and Delaware and Maryland this evening, with a
chance of thunder for MIV and ACY. This activity is expected to
diminish later this evening and overnight. Areas of fog and
drizzle will likely develop later tonight where it hasn't formed
yet. Winds out of the east- northeast with gusts up to 20 kts
at times.
Monday...Expect IFR conditions to gradually improve to MVFR
during the afternoon from northwest to southeast at all TAF
sites. Conditions may even improve to VFR, especially for ABE
and RDG. Winds will variable, generally less than 5-10 kts.
Outlook...
Monday night...IFR/LIFR CIGs/VSBYs in fog and stratus. S-SW winds 5
kt or less.
Tuesday...Mostly VFR. Potential for afternoon SHRA/TSRA. W-NW
winds less than 10 kt.
Wednesday...Mostly VFR. Light East winds become SE 10-15 kt.
Stronger winds possible at KACY. Potential for SHRA/TSRA late in the
day and SHRA at night, mainly at terminals south and west of KPHL.
Thursday through Friday...SHRA/TSRA possible throughout the period.
SE winds 5-10 kt Thursday become SW on Friday.
&&
.MARINE...
Tonight...The SCA remains in effect from Sandy Hook NJ to Cape
Henlopen and lower DE Bay, and is in effect through early
tonight. Across this area, east-northeast wind gusts of 25 kts
with seas building 3 to 6 ft, except around 2 ft in lower DE
Bay.
Monday...Sub-SCA conditions expected at this time.
Outlook...
Monday night...VSBY restrictions possible in fog. Wind/seas below
SCA thresholds.
Tuesday through Friday...Winds and seas below SCA levels.
Rip Currents...
Through this evening...The risk for the development of
dangerous rip currents is moderate for the NJ beaches and low
for the DE beaches.
Monday...A residual moderate risk for the development of
dangerous rip currents is expected along the Monmouth and Ocean
County beaches. For the rest of the NJ shore and DE, a low risk
for the development of dangerous rip currents is forecast.
Remember, a low risk of rip currents does not mean no risk!
Life threatening rip currents often still occur near jetties,
reefs, and piers. The vast majority of rip current victims swam
at unguarded beaches. ALWAYS SWIM IN THE PRESENCE OF A
LIFEGUARD.
&&
.TIDES/COASTAL FLOODING...
A Coastal Flood Advisory has been cancelled for the northern
New Jersey coastline from Ocean county northward through
Middlesex county, as high tide has passed. However, it remains
in effect for all of the tidal Delaware River and the upper
portions of the Delware Bay.
An east to northeast flow has continue to has also not allowed
much water from the tidal Delaware River and Delware Bay to
evacuate efficiently. Another factor that may lead to elevated
water levels is the runoff from earlier rainfall across portions
of the area may exacerbate any localized flooding in these
areas. This may especially be true for the northern portion of
the tidal Delaware River from Philadelphia northward.
This looks to be the only high tide that will need an advisory
at this time, with the exception of possible the upper portions
of the tidal Delaware River which may continue to have elevated
water levels Monday night.
&&
.EQUIPMENT...
The Sandy Hook NOS tide gauge (SDHN4) remains out of service.
CORMS is addressing the problem. There is currently no estimated
time for a return to service.
