What forecasters said that day

The local office's own words before this areal flood 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 areal flood warning went out at Jun 20, 4:37 AM EDT, 1 minute earlier.

Area forecast discussion, Jun 20, 4:37 AM EDT, 1 minute before
Area Forecast Discussion
National Weather Service Mount Holly NJ
437 AM EDT Thu Jun 20 2019

.SYNOPSIS...
An area of low pressure will pass north of the region today. A cold
front will move through tonight. High pressure will gradually build
in Friday night and remain nearby through Sunday. A warm front is
expected to move through Sunday night. A frontal system will likely
affect the area Monday and Tuesday.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Stationary boundary lies from eastern Pennsylvania and bisects New
Jersey. Showers and thunderstorms continue to fire up along this
boundary, and with abundant low level moisture, these storms will
continue to produce heavy rain. As the boundary lifts north as a
warm front, convection will lift north as well into daybreak.
Thunderstorms will become more isolated during this time, but
locally heavy rain remains.

Numerous Flash Flood and Flood Warnings remain in effect as some
areas have picked up as much as 4-6 inches of rain in the last 12
hours. Although rain lifts north and tapers off this morning, the
flooding should continue.

For the rest of the day, persistent southerly flow increases behind
the passage of the warm front. This will usher a warm and humid
airmass into the region, and with abundant moisture leftover from
the rainfall yesterday and through this morning, this will push
surface dewpoints well into the lower 70s. Combined with highs in
the 80s, the heat index will approach 90 south of I-76, and will be
in the lower 90s across much of southern New Jersey and Delmarva.

Low pressure over the Great Lakes lifts to the northeast throughout
the day, and this drags a cold front east late in the day. A pre-
frontal trough develops out ahead of the front, and this trough will
trigger another round of showers and thunderstorms starting late in
the afternoon.

SB CAPE values will rise to 1500-2000 J/kg across the northern half
of the forecast area and to 2000-3000 J/kg across Delmarva, southern
New Jersey, and southeast Pennsylvania. 0-6 km Bulk Shear will be
around 35-45 kt, and PWATs will be up around 2 inches. There is a
Slight Risk for severe weather later today and tonight, and
thunderstorms that develop will be capable of torrential rain,
damaging winds, and frequent and deadly lightning strikes.

With the threat of heavy rain once again, the Flash Flood Watch
remains in effect for all of southeast Pennsylvania, most of New
Jersey, and northern portions of Delmarva.

Given areas where there is already flooding occurring, it will not
take much rainfall to result in additional flooding.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM FRIDAY/...
Flash Flood Watch remains in effect until 1 am.

Cold front slowly works its way into the western portions of the
forecast area this evening, and then crosses the region during the
overnight.

Showers and thunderstorms will continue through much of the evening
hours, and then storms lose their intensity as the evening
progresses with the loss of diurnal heating. PWATs drop to around
1.75 inches, and heavy rain remains a threat for most of tonight.

Showers and storms taper off after midnight, and some dryer air
begins to work its way in from the north and west. Surface dewpoints
begin to drop, but with abundant moisture on the ground, can expect
fog to develop once again.

&&

.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
Overview...

We will finally see some changes in the long term, as the mid-
Atlantic will for a few days find itself downstream of a ridge over
the Great Lakes and upstream a departing trough associated with a
departing surface low. This will mean a well-deserved multi-day
break in rainfall across our area, as high pressure builds in to the
northwest and guides any ridge-riding convective disturbances to our
south. And such disturbances will exist, as the ridging to our west
is not very long in wavelength, and ample troughing continues to
exist further west, which will keep the pattern active over the
Plains and Midwest. That then raises questions for our weather going
further into next week. It appears likely the ridge to our west will
start to flatten out, with renewed troughing pushing into the Great
Lakes. Thus, it is likely we will be dealing with another frontal
system by early next week. Early indications are that we will not
deal with such a prolonged and impactful stretch of unsettled
weather. However, the one constant in the hemispheric pattern
remains a seemingly unbreakable block over Greenland, which should
briefly relax over the weekend but then looks to build right back in
next week. Because of this, even as longwave ridging attempts to
build over the CONUS, we continue to see frequent troughing over
southern Canada with the trough unable to lift out. This leaves us
vulnerable to additional frontal disturbances even in a pattern
which is trying to trend warmer and drier overall. We may get there
eventually, but for now after the break over the weekend it appears
next week will be on the unsettled side with a return of higher
humidity and occasional shower and storm chances.

Dailies...

Friday... Deepening low pressure will be pulling away from the
region. Gusty northwesterly flow is likely given the pressure
gradient of this unseasonably strong low. Gusts to 30mph are
possible. Lingering showers are also possible especially in the
morning, but should depart from west to east with all areas likely
dry by early to mid afternoon. Highs running a few to several
degrees below normal with cooler air to the northwest being advected
in and the trough axis moving overhead then swinging gradually to
the east.

Saturday-Sunday... A pleasant and quiet weekend awaits us as high
pressure moves overhead. The trough from Friday will still not have
fully pulled away by Saturday, and flow will remain northerly or
northwesterly, so this will keep temperatures a little below normal
even with sunshine. By Sunday, winds turn out of the west as the
trough pushes further off to the east, and we start to advect in
warmer air. So Sunday looks several degrees warmer than Saturday,
with highs mostly in the mid 80s and dew points creeping up a little
but still comfortable.

Monday-Tuesday... A warm frontal passage is expected Sunday night or
early Monday as low pressure tracks into the Great Lakes. Time
constraints prevented any detailed analysis for this period, but the
chance for showers and thunderstorms looks to return. In addition,
behind the warm front, higher dew points and warmer temperatures are
expected, and some areas may see highs approach 90 by Monday.

Mid-week/beyond... Low confidence. Guidance is widely spread on
whether the early week system or an additional frontal system may
continue to impact the region, or if high pressure and hotter
weather will build in. No strong preference at this time.

&&

.AVIATION /09Z THURSDAY THROUGH MONDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY and surrounding areas.

Most terminals will likely be IFR and locally LIFR early this
morning. This should gradually improve to MVFR and VFR through mid-
morning, but low confidence on the speed of improvements. Light and
variable winds will turn southwesterly at 5 to 10 kt through the
day. Tstms possible across the region this afternoon. Some storms
could be strong to severe with gusty winds.

Tonight...A period of MVFR or IFR ceilings is possible. By late
tonight, a cold frontal passage will turn winds more northwesterly,
which should start to scour out the lower ceilings towards daybreak
Friday. Showers possible with a lingering tstm also possible early
southeast of PHL.

Outlook...

Friday-Friday night... MVFR possible in the morning, but improving
to VFR. Northwest winds 15 to 20 kt with gusts as high as 30 kt,
diminishing to 10 kt overnight.

Saturday-Sunday... VFR. High confidence. Northwest winds of 10 kt
gusting to 20 kt on Saturday becoming westerly or southwesterly at 5
to 10 kt Sunday.

Sunday night-Monday... Periods of cig and vsby restrictions
possible along with scattered showers and tstms. Southwest winds
of 5 to 10 kt.

&&

.MARINE...
Visibilities have dropped to under one mile along the coast, so
will go ahead and issue a Marine Dense Fog Advisory that will
run until 10 am. VSBYs should improve then, but it is possible
that the Marine Dense Fog Advisory may have to be extended for
the rest of the day, depending on how bad the fog is and if it
lifts or not.

Otherwise, sub-Small Craft Advisory conditions on tap for
today.

Showers and thunderstorms with frequent lightning, heavy rain
resulting in lowered VSBY, and wind gusts in excess of 34 kt will
affect the waters later today and tonight.

SCA conditions develop on the waters after midnight tonight. Fog is
possible again.

Outlook...

Friday-Friday night... SCA conditions expected and a period of
northwesterly gales is possible especially over the southern marine
zones. Seas 3 to 5 ft. Conditions may drop below SCA Friday night as
seas fall to 2 to 4 ft but gusts will likely linger close to 25 kt.

Saturday-Monday... SCA conditions may linger into early Saturday but
sub-SCA conditions expected for most of the weekend into early next
week.

Rip Currents...

There is a low risk for the development of dangerous rip currents at
the NJ and DE ocean beaches today. Winds become south with waves in
the surf zone about 3 feet.
