Special Weather Statement, NWS Philadelphia/Mount Holly

Area Forecast Discussion
National Weather Service Mount Holly NJ
1238 AM EDT TUE JUL 5 2016

.SYNOPSIS...
A warm front will continue lifting northward into the area
overnight. A wave of low pressure tracking along the front will
probably pass close to Philadelphia and Atlantic city early
Tuesday before exiting off the coast by late Tuesday morning. The
front will dissipate over the area during the middle of the week.
A series of fast-moving disturbances may pass through the area
Thursday and Friday. A cold front is expected to move through
Saturday. High pressure builds in late in the weekend.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
A swath of half to three quarter inch rainfall amounts have
already occurred from northern Delaware eastward to the central
part of the Jersey Shore. Lesser amounts have fallen in the
remainder of our forecast area. The first batch of moderate rain
was lifting northeastward through the Poconos, the Lehigh Valley,
and central and northern New Jersey around 1230 am.

Another round of rain was beginning to move into southeastern
Pennsylvania and the upper Delmarva region from the west. The
showers extended back into northern West Virginia. The area of
showers is expected to become enhanced overnight in response to an
upper level jet overhead. We continue to expect a period of
moderate to heavy rainfall and isolated thunderstorms, especially
across the central part of our forecast area from southeastern
Pennsylvania and the far upper Delmarva into southern and central
New Jersey. A Flash Flood Watch remains in effect for that area
until 1000 am.

A southeast to southwest wind up to 10 mph is expected overnight.
However, there could be stronger gusts with any thunderstorms.
Temperatures should not fall much due to the cloud cover and
southerly flow.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH 6 AM WEDNESDAY/...
The frontal boundary will push southward through the region on
Tuesday with steadier showers ending by mid-morning. Models
disagree regarding deep enough available moisture for afternoon
precipitation. The ECMWF has considerable drying aloft as the KI
which is near 36C overnight dries to below 25C by Tuesday evening
which argues against much if any afternoon redevelopment.

Majority of this period uses elements of MAV, MET and ECMWF MOS
guidance. Wind gusts were raised some for tomorrow afternoon given
the potential for favorable mixing. Highs will be in the 80's.

&&

.LONG TERM /WEDNESDAY THROUGH TUESDAY/...
Surface high pressure and upper ridge centered over the Gulf of
Mexico and southwestern Atlantic Ocean will briefly build poleward
up the eastern seaboard on Wednesday. This will allow for the
summer heat that has primarily been confined to the Gulf Coast,
Intermountain West and Great Plains regions in recent weeks to
expand north and eastward into the mid-Atlantic states during the
mid to late week. There is a potential for multiple 90-degree days
Wednesday through Saturday. On Wednesday, the heat index should be
similar to dry bulb temperatures with a drier airmass in place and
dewpoints in the mid 60s in E PA and NJ. Note, dewpoints may be in
the lower 70s in Delmarva on Wednesday but temperatures should be
slightly cooler so heat indices are expected to fall short of
criteria for heat headlines. It will feel increasingly muggy by
Thursday as winds in the boundary layer back more out of the
south. When factoring in the humidity, excessive heat headlines
may be needed, especially for the urban corridor, where heat
indices may peak in the upper 90s to near 100F. As noted
yesterday, there is still forecast uncertainty regarding how hot
it will get and if we will get to excessive heat warning criteria
each day. This is due to the fact that we are expected to be
positioned downstream of the 'ring of fire' setup. In this
pattern, recurrent MCS development is favored over the Midwest
region as a series of fast-moving shortwave disturbances track
within the belt of stronger upper-level westerlies that reside
along the northern periphery of the flattened ridge. There is
little skill in timing these systems this far in advance, but
debris clouds and precipitation could keep temperatures down
several degrees below what is currently forecast for high
temperatures if one or more of these systems move into the
forecast area during the day. There is even greater uncertainty
for forecast temperatures on Saturday due uncertainty in
timing/position of a cold front. Saturday could wind up being the
hottest day ahead of the cold front. Conversely, a fropa occurring
earlier in the day would mitigate our risk of enduring another
excessive heat day on Saturday.

On Wednesday, isolated showers or storms may develop in vicinity
of the stalled surface trough in the Delmarva and far southern NJ
during peak heating. We continue to include chances for showers
and storms in the forecast each day from Thursday through
Saturday. PoPs are relatively low (20-30 percent) Thursday and
Friday due to low predictability in timing these fast-moving
disturbances. Slightly higher PoPs are forecast Saturday owing to
the arrival of better lift with the cold front. The potential of
more organized strong to severe thunderstorm events increase by
Friday-Saturday but its highly uncertain this far out until the
timing of these subtle disturbances and the mesoscale details are
able to be resolved.

Northwest flow behind the front will usher in cooler air later in
the weekend, marking an end to the heatwave. Near normal
temperatures are favored Sunday and Monday. It should also be dry
with high pressure build in.

&&

.AVIATION /06Z TUESDAY THROUGH SATURDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.

Overnight: mvfr variable ifr conditions in showery rains with
isolated or scattered embedded thunderstorms after 06z/5.
Uncertainty regarding any thunderstorms to directly impact TAF
sites attm from 07-11z but have added to the TAFS of
PHL/ILG/MIV/ACY.

Southerly winds generally around 10 knots may turn light
northeast toward dawn vcnty KPHL eastward. Please see TAFS for
details.

Tuesday: Ceilings and vsbys will gradually lift by late morning
to VFR. Showers should quickly end by mid or late morning from
west to east. Winds will shift to westerly around 10 knots with
afternoon gusts as high as 20 knots.

OUTLOOK...
Tuesday night through Thursday morning...Mainly VFR. Patchy fog
could develop late Wednesday night-early Thursday morning.

Thursday afternoon through Saturday...Predominately VFR. However,
multiple rounds of showers and storms possible. Local/temporary
flight restrictions possible in vicinity of heavier showers or
storms. Chance for precip is greatest Saturday when a cold front
arrives. Otherwise, low confidence in timing each disturbance
moving through.

&&

.MARINE...
Wave heights from three to four feet are expected for tonight and
during the day on Tuesday. Southerly wind gusts may approach 20
knots at times tonight then become westerly on Tuesday. A few
thunderstorms are possibile as well on the coastal waters.

OUTLOOK...
Tuesday night through Saturday...Winds and seas below SCA
criteria. Chances for thunderstorms each day Thursday through
Saturday. A few of these storms could produce locally higher winds
and seas.

RIP CURRENTS...
We have forecast a low risk for Tuesday. It may be a low enhanced
risk on some of the beaches. There should be a 3 to 4 foot
southerly swell with a 6 second period to start the day, slowly
settling down in the afternoon. Despite still being near the new
moon phase, a westerly offshore wind of 10 to 15 mph forecasts a
low risk. Showers and any thunderstorms should end by 10 am
Tuesday though it may take a while for bright sunshine to return
during the afternoon.
