DRAGWhat forecasters said that day
The local office's own words before this special marine warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Philadelphia/Mount Holly wrote its last area forecast discussion before this special marine warning went out at Jul 14, 4:05 PM EDT, 1 hour 48 minutes earlier.
Area forecast discussion, Jul 14, 4:05 PM EDT, 1 hour 48 minutes before
Area Forecast Discussion
National Weather Service Mount Holly NJ
405 PM EDT Fri Jul 14 2017
.SYNOPSIS...
A cold front will move through the region late tonight into
Saturday morning. This front will stall off the Carolina coast
through this remainder of the weekend while high pressure builds
in from the Midwest. An area of low pressure develops along the
stalled boundary and starts to move northward into our area
late Monday and Tuesday. High pressure will build into the
region for Wednesday. Another cold front will slowly drop down
from the north on Thursday.
&&
.NEAR TERM /THROUGH TONIGHT/...
A 1012 mb surface low was analyzed near the eastern shore of
Lake Ontario in central NY. The frontal structure of this system
included a cold front that extended southwestward from the low
across the Ohio Valley a warm front that extended to the south
into central PA and curved to the east across near the PA-DE
border and adjacent southern NJ.
The focus for the active weather has shifted farther south than
yesterday by only about 50 miles, which includes far SE PA, S NJ and
Delmarva. The main concerns through this evening will be locally
heavy rainfall/flash flooding and severe thunderstorms although the
the heat will also be an issue in mid Delmarva until storms arrive
late in the day.
Severe Thunderstorm Watch #414 is in effect for SE PA, including
Philadelphia, as well as S NJ, E MD and DE through 9 PM. A line
of strong storms are already starting to organize near the
differential heating boundary/stationary front in southern PA.
Strong heating south of the front has resulted in a moderately
unstable airmass with MLCAPE ranging from around 1000 J/kg in
far SE PA and adjacent S NJ to 2000+ J/kg over the mid Delmarva,
per SPC mesoanalysis. It is these areas along and south of the
warm front that will be conducive for severe thunderstorms.
Expect to see pockets of damaging winds within the line segments
that move across the Watch area. Similar to yesterday, there may
be a brief spin up with storms that track along the stationary
front, where winds are backed out of the SE and E.
A Flash Flood Watch for portions of SE PA, S NJ, NE MD and DE
through midnight. These locations will be closest the frontal
boundary, where the focus for convection will be later this
afternoon and evening. An increasingly stable boundary layer
farther north into NE PA and N NJ will have a tough time
supporting deeper convective updrafts needed for heavy rainfall
rates and flash flooding. Poor drainage flooding is still a
possibility though.
A Heat Advisory is in effect for central and southern DE and
adjacent eastern Maryland. Temperatures are close to forecast
but dewpoints are several degrees higher (mid to upper 70s vs
forecast in the low to mid 70s). Observed heat indices are in
the 100-105F range as of 2 PM this afternoon.
Expect storm intensity to gradually diminish toward sunset this
evening. However, like yesterday, expect at least scattered
showers and storms to continue after dark, particularly where
the residual unstable airmass has not been worked over from
prior convection. Widely scattered leftover showers and isolated
thunderstorms were advertised along and east of I-95 for the
overnight.
Additional convection may reach NE PA and NW NJ close to
midnight. This is in association with a line of showers and
storms that has developed along the cold front in central NY
this afternoon. Hi-res CAM guidance are in general agreement
with these showers and storms weakening after dark and
eventually dissipating overnight before it the Fall Line.
Otherwise, low clouds will persist through much of the night
across eastern PA and much of NJ as a result of continued
onshore flow to the north of the front. Any breaks in the cloud
cover that occur where it has rained this afternoon could lead
to the development of fog tonight. Fog is currently expected to
be patchy in coverage.
Forecast low temperatures are in the middle 60s across NE PA and
NW NJ and lower 70s from Philadelphia southward.
&&
.SHORT TERM /SATURDAY/...
The frontal boundary that has been linger over the area for the
past few days will finally move off the coast on Saturday as
high pressure builds in from the Midwest. W-NW winds behind the
front will advect drier air into the region. This should result
in low clouds gradually clearing from west to east during the
day.
A delayed arrival of the drier air as well as the passage of a
mid-level shortwave trough could allow for isolated showers to
develop during the morning and possible early afternoon in the
coastal plain of S NJ and Delmarva.
Forecast high temperatures are in the 70s in the southern
Poconos and mid to upper 80s across the rest of the area.
&&
.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
Saturday night and Sunday...The cold front drops stalls off the
Carolina coast, where it remains through the rest of the
weekend. Weak high pressure will build into our area for the
weekend, keeping us dry for at least a couple of days. Might be
a bit cloudy to start the weekend off but overall skies will
become mostly to partly sunny across the region. With drier air
in place, it should feel pretty comfortable outside even with
highs reaching into the mid to upper 80s.
Monday through Tuesday...A low pressure system will develop
along the stalled boundary to our south and will start to move
northward on Monday. The models continue to show the low moving
up through Virginia on Monday and then into Delmarva and through
southern New Jersey on Tuesday. The low then pushes to the
north and east of our area late Tuesday into Wednesday. A chance
for showers and thunderstorms will exist as the surface low
makes its way into our area. A surface trough also develops
across our area again and this would provide a good source of
lift, promoting convective activity. In addition, an upper level
trough will build across the Mid- Atlantic. This will help to
deepen the southerly flow into our region as the atmosphere
becomes more unstable. Best timing for convection, at this
juncture, looks to be mainly during the afternoon and evening
hours.
Wednesday through Thursday...High pressure will build in behind
the departing low with clearing expected for Wednesday. The
upper trough slides to the east during this time. A cold front
will start to drop down from the north on Thursday. As the high
builds in, we will see a return to more of a west to southwest
flow, ushering in some warmer, and moister, air to the region.
Highs will start to creep back up and into the upper 80s to
lower 90s by Wednesday and then into the l ow to mid 90s for
Thursday. Increasing moisture will also mean increased humidity
across the area. Seems reasonable that some showers and
thunderstorms may develop during the afternoon and evening on
both days but location of activity is too difficult to pinpoint
this far out.
&&
.AVIATION /19Z FRIDAY THROUGH WEDNESDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.
IFR conditions with low clouds have held strong at PHL, PNE and
TTN with these terminals situated north of a stationary front.
Breaks in the clouds farther south have resulted in the
development of strong thunderstorms. Based on 1930Z radar, these
storms have a direct path through ILG-MIV-ACY over the next few
hours. Torrential downpours and strong winds with these storms
could bring a period of near zero visibility and peak wind
gusts of 30-50 kt.
It is expected that the low clouds and IFR CIGs will linger
into tonight from PHL northward. It is less clear if these low
clouds makes it into ILG, MIV or ACY as they should be situated
on the southern edge of the stratus deck near the stationary
front. Even if the stratus doesn't make it that far south, fog
could contribute to flight restrictions, especially overnight.
CIGs should lift during the mid to late morning on Saturday as
the front moves off the coast. There is still uncertainty
regarding how quickly they improve but latest thinking is
improvement to VFR occurs from west to east between 14Z and 18Z.
Winds 5-10 kt will vary from NE across the northern terminals to
SE across the southern terminals through sunset. An easterly
component to the winds is favored for tonight but they could
become light and variable in spots. Winds then shift out of the
west and northwest between 7 and 12 kt on Saturday in wake of a
cold fropa.
OUTLOOK...
Sunday...VFR conditions expected. Light northwest winds early,
becoming south to southeast around 10 knots or less.
Monday through Wednesday...Mainly VFR conditions expected.
Afternoon showers and thunderstorms with MVFR or lower
conditions possible. South to southeast winds around 10 knots.
&&
.MARINE...
A stalled frontal boundary is forecast will remain near the DE
Bay and adjacent coastal waters through tonight before a cold
front moves in from the NW on Saturday.
Anybody on the coastal Atlantic waters south of Little Egg
Inlet and in the Delaware Bay is strongly encouraged to pay
close attention to Special Marine Warnings that are issued.
These storms contain strong winds, hail and dangerous lightning,
which could threaten boaters that do not take shelter. Storms
should generally weaken after dark but the threat for at least
isolated storms will linger into the night.
Easterly winds 5-10 kt with gusts to 15 kt has allowed seas to
build to 3-4 ft with a few buoys approaching 5 ft. Winds should
back slightly out of the E-SE late tonight but remain at these
speeds.
A wind shift from the west will occur behind a cold front on
Saturday morning. Winds and seas will remain below SCA criteria.
OUTLOOK...
Saturday night through Wednesday...Sub-Small Craft Advisory
conditions are expected on the area waters. Locally strong
winds may accompany thunderstorms Monday through Wednesday,
especially during the afternoon and evening hours.
RIP CURRENTS...
There risk for the development of dangerous rip currents were
increased to moderate for this afternoon at the NJ shore, where
an onshore flow has lead to an increase in surf to 3 to 4 ft.
The risk is low for Delaware this afternoon.
A low risk is anticipated for Saturday along the NJ and DE
coasts.
