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 Jul 10, 4:04 AM EDT, 4 hours 31 minutes earlier.

Area forecast discussion, Jul 10, 4:04 AM EDT, 4 hours 31 minutes before
Area Forecast Discussion
National Weather Service Mount Holly NJ
404 AM EDT Mon Jul 10 2023

.SYNOPSIS...
Low pressure will drift off the New Jersey coast toward Long
Island tonight. The system is forecast to lift slowly through
New England on Monday and Tuesday. High pressure is expected to
follow from the west and southwest for the mid week period.
Another frontal boundary may approach from the northwest late in
the week and over the weekend.

&&

.NEAR TERM /THROUGH TONIGHT/...
River flooding continues through the overnight as heavy rain
put down 3 to 5 inches of rain fell over eastern PA into
northern NJ. Most river gages have crested and additional
flooding from yesterday's precip is not expected. Even so, as
the previous discussion mentioned, be extra cautious traveling
tonight even though the rain has ended, and do not drive through
flooded roadways.

With sufficient low level moisture still sitting in place, low
clouds and patchy fog has persisted through much of the night
albeit not quite as pessimistic as the GLAMP was initially
suggesting. Winds remain generally less than 10 kts and favoring
a northwesterly direction.

Low pressure is anticipated to move across central NY this
afternoon and evening which will bring another round of positive
vorticity advection and that may be enough to trigger a round
of at least isolated showers and thunderstorms late this
afternoon, mainly north and west of Philadelphia. Behind the
low pressure system, stronger northwest flow develops and this
will drive in drier air late. The drier air and faster storm
relative flow should mean that any thunderstorms will be fairly
quick, thus minimizing the threat of localized heavy rain or
additonal flooding. Highs this afternoon should warm into the
mid 80s which is close to near normal.

&&

.SHORT TERM /TUESDAY THROUGH WEDNESDAY/...
A strong mid level low is forecast to meander over lower Hudson
Bay in Canada and vicinity on Tuesday and Wednesday. We will
likely remain on the edge of its influence.

A continued westerly flow on Tuesday should continue to reduce
humidity levels somewhat. The trend is forecast to persist into
Wednesday. Both days are expected to be precipitation-free as
the surface low moves farther away from us and as high pressure
builds across our region.

Tuesday's maximum temperatures should be in the middle and
upper 80s with dew point readings dropping into the 60s. The air
mass will likely modify a bit for Wednesday, with afternoon
temperatures rising into the upper 80s and lower 90s at that
time.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
The mid level low is expected to remain over northern Ontario,
northeastern Manitoba and adjacent Hudson Bay from Wednesday
night through Friday and it may begin to drop southward over the
weekend. We should remain on the periphery of its influence
through the period.

Surface high pressure is anticipated to move out to sea late in
the week. Warm southerly return flow is forecast towards the end
of the week which will bring a return of higher humidity values
on the back side of the high. Several waves of positive
vorticity advection swing through which should provide enough
lift to trigger some diurnally driven afternoon and evening
showers and thunderstorms each day from Thursday through Sunday.

Temperatures will likely remain seasonable through the period.

&&

.AVIATION /07Z MONDAY THROUGH FRIDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.

Rest of Tonight...Generally low MVFR cigs across the terminals
through the rest of this morning with some brief periods of IFR/LIFR
fog possible at all terminals. By day break, chances for IFR
should be reduced. Variable wind less than 10 kt tending more
NW. Medium confidence.

Today...MVFR ceilings may linger for a few hours into the
morning quickly becoming mainly VFR conditions. Afternoon
isolated showers and thunderstorms could briefly lower
conditions to MVFR or IFR. Northwest wind 5 to 10 knots. Medium
confidence.

Outlook...

Tuesday...Mainly VFR. Northwest to west wind around 10 knots.
Medium to high confidence.

Wednesday...Mainly VFR. Some early morning ceiling and
visibility restrictions are possible. Southwest to south wind
around 10 knots. Medium to high confidence.

Thursday...Mainly VFR. Some early morning ceiling and
visibility restrictions are possible. A chance of afternoon and
evening showers and thunderstorms. Southwest to south wind 10 to
15 knots. Medium confidence.

Friday...Mainly VFR. Some early morning ceiling and visibility
restrictions are possible. A chance of afternoon and evening
showers and thunderstorms. West to southwest wind around 10
knots. Medium confidence.

&&

.MARINE...
Southwest winds overnight will become westerly by mid afternoon.
Seas are running between 2 to 3 feet on an ESE swell between 7
to 10 seconds at buoy 44009. Waves on Delaware Bay should be 2
feet or less.

Outlook...

Tuesday through Friday...No marine headlines are anticipated.

Rip currents...

There is a LOW risk for the development of dangerous rip
currents for the New Jersey and Delaware beaches through Monday.
Waves in the surf zone will remain around 2 feet as the tide is
going out however as the tide is coming in later this morning,
we could see some waves in the 3-4 foot range. Westerly winds 5
to 10 mph, except where any weak local sea breeze develops. A
medium period southeasterly swell is expected to continue
through this time.

For Tuesday there is a LOW risk of rip currents as well.
Conditions will remain very similar to Monday, with a minimal SE
swell, and winds tending W to SW around 5 to 10 mph.

&&

.HYDROLOGY...
3 to 5 inches of rainfall fell across much of our region to the
northwest of I-95 today, with locally higher amounts, while
only around an inch (locally higher) fell to the southeast
toward the Delmarva and coastal NJ. Locally 2 to 3 inches fell
across portions of northern/central Delaware as well. That has
resulted in significant rises on area creeks and streams. While
the threat of flash-flooding is ending as rainfall has ended and
water drains from area roadways in lower-lying areas, some areal
flood warnings will remain in effect overnight. River flooding
will be very localized as many area rivers were running very low
prior to this event, but some minor flooding is now forecast
along portions of the Schuylkill River, Brandywine Creek in
southeast PA, and parts of the Raritan and Ramapo Rivers in
northern NJ.

&&

.CLIMATE...
Widespread heavy rainfall fell across our forecast area
yesterday with a new recording being set at Reading. 5.35" of
rain fell breaking the old record of 3.74" from 1952. 5.35"
represents the 7th highest one day today at Reading since the
the period of record beginning in 1858.
