Special Weather Statement, NWS Philadelphia/Mount Holly

Area Forecast Discussion
National Weather Service Mount Holly NJ
321 PM EDT THU JUL 7 2016

.SYNOPSIS...
A surface trough will remain in our region through Friday morning. A
backdoor front will slowly sink southward into the region on Friday.
A cold front will cross the region Saturday night. High pressure
will begin to build into the region late Sunday, moving over the
region on Monday and Tuesday, and then move offshore on Wednesday.

&&

.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...
Upper level short wave trough should shift south of our region
through the overnight hours. As it does, some showers may move into
Delmarva through the evening hours, but otherwise should be a dry
night.

Otherwise, expect it to be similar to last night with the still high
dew point temperatures limiting radiational cooling at night (lows
across the region should be in the 70s, except in the higher terrain
of the Poconos and NW NJ where 60s will be possible).

&&

.SHORT TERM /6 AM FRIDAY MORNING THROUGH 6 PM FRIDAY/...
The main story remains the heat. No changes to the heat headlines
with this package. Heat index values tomorrow will be very close to
what we are seeing today, especially if thunderstorms hold off until
later in the afternoon.

Another concern is thunderstorms...The next upper level short wave
trough should cross our region through the afternoon and evening
hours. . Given how warm even the mid and upper levels are, surface
based instability should be a bit limited, limiting risk for any
gusty winds with the thunderstorms. As mentioned by the previous
shift, there is some potential for downbursts/gusty winds as there
could be a shallow dry layer in the mid and upper levels.
Additionally, as has been the case the last few days, very high
precipitable water values could lead to a flash flooding threat.
Given the current flash flood watch, will not issue a watch at this
time, but will mention the risk in the HWO.

&&

.LONG TERM /FRIDAY NIGHT THROUGH THURSDAY/...
Friday night...Showers and thunderstorms will be around Friday night
as a shortwave crosses and exits the region. Instability increases
through the night and we anticipate showers and thunderstorms
continuing across the region through the overnight hours. With PWATs
remaining near 2 inches, any showers or thunderstorms will be
efficient rainmakers and heavy rain will occur.

Saturday...Saturday looks to be the last day of the current heat
wave. Winds look stronger for Saturday and with better mixing
occurring, we should see dewpoints dropping during the daytime,
allowing for lower heat index values. In addition, lingering cloud
cover will limit max temperatures a bit, especially across our
northern areas. Highest temperatures look to be across Delmarva and
Southern New Jersey as the clouds may clear by afternoon. Based on
the current forecast, it doesn't look like heat headlines will be
needed for Saturday as heat index values fall below our
heat criteria. Convection will once again will possible on Saturday.

Sunday...Cooler and drier air arrives behind the departing cold
front and we see a little relief from the oppressive conditions of
the previous week. Temperatures will rise well into the 80s but with
dry air across the region it will not feel so sticky outside, in
fact it will actually feel fairly pleasant! With a surface trough
lingering near the region, we may see a few showers develop across
northern NJ and the Poconos. Otherwise, most areas will remain dry
through Sunday.

Monday through Wednesday...High pressure will build across the
region on Monday, shifting offshore through Wednesday. Slightly
cooler conditions prevail as we remain closer to the climatological
normals for the region, mainly mid to upper 80s. Dewpoints remain
well below 70 through the period which will help to keep the hot and
humid conditions, like we have had recently, at bay. Expect dry
weather to continue from Monday through Wednesday.

Thursday...Uncertainty exists for Thursday as the models do not
agree on the setup across the region. With the high offshore, we
should see a more southerly flow develop. We have included some low
pops for showers and thunderstorms but until the models clear up a
bit in the coming days, the confidence this far out is fairly low.

&&

.AVIATION /19Z THURSDAY THROUGH TUESDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY and surrounding areas.

VFR conditions should continue through at least 06Z. After 06Z, as
we have seen the last few nights, patchy light fog could develop
primarily at the TAF sites outside of the urban corridor (KABE,
KMIV, KACY, KRDG). MVFR visibilities will be possible with the fog.
Through the day tomorrow, mostly VFR conditions are expected until
scattered showers and thunderstorms begin to develop in the
afternoon. Variable and gusty winds and IFR conditions will be
possible with the strongest storms that develop tomorrow.

Outlook...

Friday night through Saturday...Mainly VFR conditions expected. A
chance of showers and thunderstorms is possible each day, with lower
conditions possible where they develop. Fog possible early Saturday.

Sunday...VFR conditions expected. West to northwest winds may gust
up to 25 knots.

Monday and Tuesday...VFR conditions expected. West to northwest
winds on Monday around 10 knots or less. Winds become light and
variable for Tuesday.

&&

.MARINE...
Winds and seas should mostly remain below SCA criteria tonight and
tomorrow. The one exception is that strong winds are possible in the
vicinity of any showers and thunderstorms this afternoon and again
tomorrow afternoon.

RIP CURRENTS: We will carry a low risk for the development of
dangerous rip currents for today. The wind direction should favor
the southwest and south. We are anticipating a 2 foot southerly
swell with a 7 second period.

The probable risk for the development of dangerous rip currents on
Friday is also low.

Outlook...

Friday night through Tuesday...Sub-Advisory conditions are expected
to continue through Tuesday. Sea and bay breezes may develop on
Friday and allow for gusts to 20 knots nearshore. A cold front moves
through the waters Saturday night with gusts near 20 knots possible
through Sunday.
