319 pm edt Fri aug 18 2017

As low pressure tracks well to our north, a cold front moves through
later tonight into early Saturday. High pressure then builds in late
Saturday and remains in place into Monday before shifting offshore.

The next cold front is scheduled to arrive during Wednesday, then
canadian high pressure builds in for Thursday and Friday.

Near term until 6 am Saturday morning
Very warm and humid airmass in place across the region with surface
dewpoints well into the 70s, and even approaching 80 in coastal
portions of southern nj. This results in an unstable environment
with sb CAPE values ranging from up to 1500 j kg across northern nj
to 2500-3000 j kg across southern nj and the delmarva. Given the
amount of instability across the region, and strong lift associated
with an approaching mid-level shortwave, active weather on tap for
this evening.

Severe thunderstorm watch #455 remains in effect until 9 pm. In
addition, with pwats close to 2.5 inches across the region,
continuing to expect heavy rain and training of thunderstorms. The
flash flood watch remains in effect until midnight, but went ahead
and added all of de and all of nj to the flash flood watch, as model
guidance continues to show a precip MAX across the southern most
portions of the forecast area, mainly associated with weak low
pressure developing along the front.

Low pressure currently north of the great lakes will lift to the
north and east tonight. This will drag a cold front through the east
coast during the overnight hours. Pre-frontal trough has developed
across central ny and pa out ahead of the front, and that pre-
frontal trough will trigger showers and strong to severe
thunderstorms across much of the forecast area this evening. The
first storms that have developed are currently moving into the
lehigh valley, but that activity will spread east through the early
evening hours. Cold front swings through the region after midnight
and during the pre-dawn hours.

After sunset, with loss of diurnal heating, should lose some of the
instability that would lead to severe storms. However, flooding
threat remains in place until the storms end, as the abundant low-
level moisture remains.

The last of the storms look to move off the nj coast around
midnight. However, abundant low level moisture remains in place as
the drier airmass will not get here until Saturday morning. As a
result, can expect widespread fog to develop when rain ends and
skies start to clear out. Cannot rule out patchy dense fog.

Lows tonight remain in the upper 60s to low 70s, except for the
delmarva where lows will be in the mid 70s and the poconos, where
lows will be in the low 60s.

Short term 6 am Saturday morning through 6 pm Saturday
Cold front should be offshore early Saturday morning, and once west
to northwest winds increase a bit, the drier airmass spreads east,
and any lingering fog will burn off. Skies clear out in the
afternoon. Dewpoints drop about 10-15 degrees, generally into the
mid 60s, but temps will be fairly warm, topping off in the upper 80s
to near 90 across the urban corridor of i-95 from trenton to
wilmington, and in the delmarva. Upper trough approaches from the
west, and this may bring isolated late day showers and thunderstorms
to far western portions of the forecast area.

Long term Saturday night through Friday
Summary... Lowering of the dew points through Sunday although
remaining warm to hot, then moistures increases again with some
convection especially Wednesday with the next cold front. A
noticeably cooler and drier airmass arrives for Thursday and Friday
in the wake of the cold front.

Synoptic overview... An upper-level trough is forecast to exit the
northeast Saturday night and Sunday, then the flow aloft turns more
zonal through early next week. Another trough is forecast to amplify
across eastern canada and the great lakes to the northeast Tuesday
into Thursday, which then remains in the northeast on Friday. We
used a blend of continuity guidance for Saturday night through
Sunday night, then blended in the 12z wpc guidance.

For Saturday night and Sunday... The axis of an upper-level trough is
forecast to slide across the region Saturday night, then quickly
move across and exit new england Sunday. A short wave embedded
within this trough is forecast to move through Saturday night,
although it may shear out to the east-northeast. While some drying
is expected to move in, enough lingering moisture and instability
combined with lift may allow for some convection to arrive from the
west before weakening. We therefore carried some slight chance pops
in Saturday evening across parts of the western zones. The flow
aloft then turns more zonal on Sunday with surface high pressure
building in. This should be accompanied by more pronounced drying,
and with plenty of heating during the day Sunday the dew points are
anticipated to lower to more comfortable levels. A northwesterly
breeze on Sunday may be light enough to allow for a sea breeze to
develop in the afternoon.

For Monday and Tuesday... The zonal flow aloft continues at least
into Tuesday. This drives high pressure eventually offshore as it
weakens some later Monday. The next upper-level trough amplifies
eastward from the midwest and upper great lakes Tuesday. This will
start to back the flow more southwesterly, and there may be a lee-
side trough present on Tuesday. As the moisture begins to increase
once again combined with the possibility for some convergence and
enough instability, some convective development is possible Tuesday
afternoon. We will carry slight chance pops as a result for Tuesday.

Any isolated convection especially inland should tend to diminish
during the night. It will turn more humid during this timeframe.

For Wednesday through Friday... The prospects for convection will
depend on the timing of an incoming cold front Wednesday. This will
be due to an upper-level trough arriving from the west, however a
pre-frontal trough may serve as the primary focus for showers and
thunderstorms. We will continue with chance pops with the idea for
at least scattered convection possible Wednesday. As of now, the
cold front should be offshore to start Thursday and canadian high
pressure builds southeastward, which arrives over our area on
Friday. A noticeably cooler and drier airmass overspreads our region
for Thursday and Friday.

Aviation 19z Friday through Wednesday
The following discussion is for kphl, kpne, kttn, kabe, krdg, kilg,
kmiv, kacy and surrounding areas.

Low-endVFR to MVFR CIGS holding tough across the terminals. There
may be some breaks toVFR from time to time, but shra tsra will
spread across the terminals ahead of a cold front approaching from
the west. Best timing for convection will be through 00z for
krdg abe, from 21-02z for the i-95 corridor terminals (kttn-kpne-
kphl-kilg), and from 22z-04z for kmiv kacy.

Heavy rain and strong and potentially damaging winds are possible
with the strongest thunderstorms. Ifr and lower conditions as well.

Once storms end, abundant low level moisture remains in place.

Ifr lifr CIGS vsbys likely in fog stratus from late tonight through
Saturday morning.

Vfr conditions develop Saturday morning. NW winds increase to 5-10
kt late Saturday morning, and back to the w-sw in the afternoon.

Isolated late day shra tsra possible at krdg kabe.


Saturday night and Sunday...VFR overall. Southwest winds 5 knots or
less becoming northwest Saturday night, then northwest winds near 10
knots Sunday.

Monday and Tuesday... MainlyVFR. Southerly winds around 10 knots.

Wednesday... Sub-vfr at times with some showers and thunderstorms
possible as a cold front arrives. Southwest winds 5-10 knots,
becoming west.

Sca remains in effect for the waters. Gusts to 25 kt will
develop on de bay this evening, and gusts to 25 kt along with 5
foot seas will develop on the ocean waters this evening.

Showers and thunderstorms will affect the waters as well this
evening, some of which may require special marine warnings. A severe
thunderstorm watch is in effect for de bay until 9 pm.

Tranquil conditions develop after midnight tonight, and will remain
in place through Saturday.

Fog may develop late tonight and into Saturday morning, which could
reduce vsbys down to 1 nm.


Saturday night through Wednesday... The conditions are anticipated to
be below small craft advisory criteria.

Rip currents...

a moderate risk for the development of dangerous rip currents
remains in place for de and nj beaches through this evening.

Thunderstorms will also impact the beaches through this evening.

The rip current risk for Saturday is currently outlooked as low.
