...A FLOOD WARNING REMAINS IN EFFECT UNTIL 400 AM EDT FOR
HUNTERDON...MERCER...MONTGOMERY...BUCKS...PHILADELPHIA AND EASTERN
DELAWARE COUNTIES...

At 1232 AM EDT, Doppler radar and automated rain gauges indicated 
heavy rain across the warned area yesterday with rainfall amounts 
generally between 1.5 and 3 inches. Locally higher amounts of 3 to 5 
inches were reported near the I-78 corridor in northwestern New 
Jersey. Runoff from the heavy rain will cause flooding of roadways, 
areas of poor drainage, and small streams and creeks.

Some locations that could experience flooding include...
Philadelphia, Trenton, Camden, Bensalem, Ewing, Norristown, Chester,
Pottstown, Phoenixville, Lansdale, West Norriton, East Norriton,
Princeton, Yeadon, Bristol, Quakertown, Perkasie, Doylestown, Byram
and Conshohocken.

The river gauge along the Neshanic River at Reaville was above flood 
stage at 7.2 ft but appears to have crested around midnight. 

The Pennypack Creek river gauge in Philadelphia was at 6.9 ft at 
1230 AM and could reach flood stage of 7.0 ft overnight.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Be especially cautious at night when it is harder to recognize the 
dangers of flooding.

Excessive runoff from heavy rainfall will cause flooding of small
creeks and streams, urban areas, highways, streets and underpasses as
well as other drainage areas and low lying spots.

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 Oct 29, 9:42 PM EDT, 19 minutes earlier.

Area forecast discussion, Oct 29, 9:42 PM EDT, 19 minutes before
Area Forecast Discussion
National Weather Service Mount Holly NJ
942 PM EDT Sun Oct 29 2017

.SYNOPSIS...
Rapidly intensifying low pressure will move across our area
overnight and then to our north through Monday morning. One
cold front passes through the region Monday afternoon, followed
by a stronger cold front Monday night. Cold high pressure works
its way across the region Tuesday through Wednesday, then moves
offshore on Wednesday. A warm front develops and passes through
the region behind the departing high Wednesday night. A cold
front will slowly work its way across the area for the end of
the week, followed by high pressure for at least part of the
weekend.

&&

.NEAR TERM /UNTIL 6 AM MONDAY MORNING/...
A 01z surface analysis placed a 983 mb low pressure center just
off the coast of Ocean County New Jersey. The water vapor imagery
shows an impressive mid level trough in the Mid-Atlantic region
taking on a negative tilt. This along with a strong jet stream
aloft is resulting in strong upper-level divergence across the
region. Therefore, a large area of rain some of which is heavy
continues to move across the area. The pivot point however
continues to quickly move northward across Delmarva.

Plenty of rain falling across the region as tropical moisture gets
entrained into the system, and reports so far indicate 1 to 4 inches
has fallen. While the rainfall rates are increased at times,
any flooding may be more of the longer duration as opposed to
the flash flooding type. We will however continue the flash
flood watch as is given some additional moderate to heavy rain.

As the deep surface low tracks north-northwestward through the
overnight, sharp pressure rises along with developing cold air
advection in its wake will combine with increased mixing. This
will result in a rapid increase in the west-northwest winds
overnight and therefore a wind advisory is continued for gusts
up to 50 mph occurring mainly toward daybreak. The strongest
winds should occur first across the southern regions of our
area.

The hourly temperature, dew point and wind grids were adjusted based
on the latest observations, then some of the LAMP guidance was
blended in for a time to assist. The Pops were adjusted a bit as an
eventual dry slot should overspread at least the southern and
eastern areas overnight allowing for a more showery pattern.

&&

.SHORT TERM /6 AM MONDAY MORNING THROUGH 6 PM MONDAY/...
The very deep low pressure system will be north of the area
Monday morning. Strong west to northwest winds will be gusty (up
to 50 mph) during the morning, before a slow decrease in the
winds during the afternoon. A drier and colder airmass will be
sweeping across the area too. Lingering showers across the nrn
half of the area before 8 a.m. will quickly come to an end by
noon (at the latest). Clouds will decrease from S to N too, with
mostly sunny skies in most areas by afternoon. Temperatures
will reach highs mostly in the mid/upper 50s.

&&

.LONG TERM /MONDAY NIGHT THROUGH SUNDAY/...
Winds continue to diminish to less than 10 mph Monday evening.
A secondary cold front will pass through the region Monday
night, and then cold high pressure will build into the region
from the west. Frost is possible for some of the areas that are
still in their growing season in NJ and PA, as lows Monday night
will drop into the low to mid 30s for the Poconos and northern
NJ, and in the upper 30s to low 40s for the rest of southern NJ
and southeast PA. Lows will be in the low to mid 40s for the
Delmarva. Dry on Tuesday with highs generally in the 50s, and
then a colder night is on tap for Tuesday night, with lows in
the upper 20s for the Poconos, and in the low to mid 30s for
most of NJ and southeast PA. The urban corridor from Trenton to
Wilmington will be several degrees warmer, generally in the
upper 30s to low 40s, and lows will be in the mid to upper 30s
in the Delmarva. Depending on how radiational cooling develops,
it is possible for temperatures to be even colder than this, and
possible for the growing season to end in several more areas.

The caveat to the low temperature forecast Tuesday night is
that high pressure will pass through the region, and mid and
high clouds associated with a developing warm from to the west
will begin to spread east sometime Tuesday night. This will have
a major impact on the low temperature forecast, as if those
clouds arrive earlier than currently anticipated, lows would end
up being several degrees warmer than currently forecast. If
later, then temperatures will be colder.

With the approach of that warm front on Wednesday, some showers
are possible for western zones late in the day, but it looks as
if any showers will hold off until Wednesday night. Model QPF
fields are light, so not expecting much rainfall.

Cold front moves through the Great Lakes and Ohio Valley late
in the week, and may begin to approach the western Appalachians
by Thursday. Some showers are possible with its passage, but
model QPF fields remain light as the bulk of the upper level
energy will pass north of the region based on latest model
guidance.

High pressure returns for the start of the weekend, and then
another frontal system may impact the area late in the weekend.

After highs generally in the 50s Tuesday and Wednesday, return
flow sets up to being unseasonable warmth to the region again
for the end of the work week with highs in the 60s and possibly
into the low 70s. More seasonal temperatures expected for the
weekend.

&&

.AVIATION /02Z MONDAY THROUGH FRIDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.

Overnight...Ceilings vary from IFR to VFR, however a period of
prevailing MVFR/IFR ceilings is expected at most terminals.
Rain heavy at times will continue to track northward across the
region resulting in significant visibility restrictions at
times, however it will taper off to some showers from south to
north overnight for most terminals. KRDG and KABE should
continue with rain through the night. Winds shift from the
north and west-northwest and increase with gusts of 30-40 knots
mainly toward morning.

Monday...VFR conditions return in the morning as clouds clear from
south to north and showers end. West-northwest winds around 20 knots
with gusts to around 40 knots through the morning, then gradually
diminish during the afternoon.

OUTLOOK...
Monday night through Wednesday: VFR, winds generally around or
under 10 knots.

Wednesday night through Friday: Sub-VFR conditions in scattered
showers. Winds still expected to be near or under 10 knots.

&&

.MARINE...
Gale Warning remains in effect through Monday as an intense
storm moves across our area tonight then to our north through
Monday. Strong easterly winds across the northern waters will
ease for a time, then increasing west-northwest winds everywhere
occurs overnight and especially early Monday morning as strong
pressure rises occur along with some cold advection and deeper
mixing. We continue with the idea that gusts stay below storm
force later tonight and early Monday morning. Rain tapers off
overnight from south to north.

Outlook...
Monday night through Tuesday...SCA conditions expected on at
least the ocean waters due to gusty westerly flow and lingering
high season.

Tuesday night through Friday...Sub-SCA conditions expected.
