What forecasters said that day

The local office's own words before this river 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 river flood warning went out at Jun 27, 9:29 PM EDT, 4 hours 48 minutes earlier.

Area forecast discussion, Jun 27, 9:29 PM EDT, 4 hours 48 minutes before
Area Forecast Discussion
National Weather Service Mount Holly NJ
929 PM EDT Tue Jun 27 2023

.SYNOPSIS...
Low pressure well to the north will cause a cold front to slowly
cross the area overnight. High pressure will briefly dominate
Thursday. Another frontal system is expected to move back in for
this weekend and could linger into early next week.

&&

.NEAR TERM /THROUGH WEDNESDAY/...
The flood watch has been cancelled. No additional flooding is
expected.

Plenty of severe and flooding action again earlier
this evening with reports of damage and localized flooding
being received. The reports will be detailed and sent out
through the late evening and into the overnight. Much of the
heavy action has ended, but a few tstms are off the DE/NJ coast
and another lingering tstm heading SE across Lancaster County
PA. The activity will slowly diminish through the overnight as
the cold front to our west will finally move through overnight.
Expect lows to drop into the 60s. Patchy fog may develop where
clouds break and winds become light.

Upper level trough will pass overhead in the wake of the surface
front for Wednesday. With a drier air mass moving in and loss of
surface forcing, don't expect coverage like today's (and nothing
like yesterday's) but some isolated to scattered showers and
thunderstorms expected with the upper level cold core during
the afternoon with the best chances for this being over NE PA
into NW NJ and lower chances farther south and west. Otherwise,
overall a cooler and less humid day is expected, with highs in
the upper 70s to lower 80s and dew points falling into the lower
to mid 60s.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/...
A dry day is expected Thursday as upper ridging builds behind the
departing H5 trough. Under mostly sunny skies, temperatures should
climb to near normal (low/mid 80s) as weak high pressure arrives.
Dew points will remain moderate (mostly low 60s) so not a bad day
overall. Beyond that, the ridge from the SW gets squashed back to
the south as H5 flow across the Plains and Midwest strengthens. A
weak low starts to form across the Great Lakes and a wavy front
develop across our area. Scattered showers and tstms will occur with
this set-up with chance pops as early as Fri afternoon. The last day
of June will have temperatures a couple degrees above normal and an
uncomfortable feel as dew points begin to climb back towards 70
again.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
A mostly unsettled pattern for the weekend and into early next week.
The wavy front remain close to our region and with some short waves
embedded in the west-southwest H5 flow aloft. We will carry high
chance or low likely pops for both Sat/Sun. but then scale things to
chance pops for Mon/Tue. A few models (12Z GFS) are showing a trough
exiting the coast Mon night/Tue with the possibility of a dry July
4th for the area. This is a bit far off in the process to have much
confidence in it happening. We'll keep the NBM's small chance pops
for Tue attm. The showery periods Fri thru the weekend will mostly
be late afternoon/early evening time periods, with plenty of dry
periods between.

Temperatures will continue to be mostly normal or perhaps a few
degrees above for the period. It'll be humid thru the period with
dew points in the upper 60s/low 70s much of the time.

&&

.AVIATION /01Z WEDNESDAY THROUGH SUNDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY AND SURROUNDING AREAS.

Through tonight...Improving conditions behind the rains which
are presently moving offshore. KACY has returned to VFR as of
late but KILG has returned to IFR as some low CIGS have
returned. Mostly lower CIGS will return before the cold front
drives drier air into the area tomorrow. We'll fcst mostly MVFR
CIGS overnight and indicate some fog possible too with all the
low level moisture across the region. Light winds becoming
mostly W towards dawn. Medium confid.

Wednesday...MVFR conditions from overnight mist/low stratus
could linger for a time into the morning with mainly VFR for the
afternoon except for brief restrictions in any showers/storms.
Best chances for showers/storms will be at ABE and TTN.

Outlook...

Wed night/Thu/Thu night... Mostly VFR. Patchy pre-dawn
   fog possible. Medium/high confid.

Fri... VFR then a chance or showers/tstms late. Lower conditions
   possible. Medium confid.

Fri night thru Sunday... Mostly VFR but scattered showers/tstms with
   lower conditions possible. Low/medium confid.

&&

.MARINE...
The Small Craft Advisory has been cancelled for our southern two
ocean zones but remains in effect through tonight for our
remaining zones over the ocean, mainly for seas 4 to 6 feet.
For Wednesday, the trend in seas will continue to be generally
downward but this will be slow meaning our waters off the coast
of NJ could stay around SCA levels much of the day. Finally,
more showers and storms are likely over the waters for the
evening and overnight period tonight and these could bring
locally higher winds/seas.

Outlook...

Wed night thru Friday... sub-SCA winds and seas expected. Fair
weather Thu and a chance of showers/tstms later Friday.

Fri night thru Mon/Tue... sub-SCA conditions with daily chances for
showers/tstms favoring the late afternoon/evening hours. Winds and
seas higher near tstms.

&&

.PHI WATCHES/WARNINGS/ADVISORIES...
PA...None.
NJ...None.
DE...None.
MD...None.
MARINE...Small Craft Advisory until 6 AM EDT Wednesday for ANZ450>453.
