What forecasters said that day

The local office's own words before this areal flood advisory 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 advisory went out at Sep 1, 10:09 PM EDT, 2 hours 22 minutes earlier.

Area forecast discussion, Sep 1, 10:09 PM EDT, 2 hours 22 minutes before
Area Forecast Discussion
National Weather Service Mount Holly NJ
1009 PM EDT Wed Sep 1 2021

.SYNOPSIS...
The remnants of Ida which are across Maryland late this afternoon
will cross our forecast area this evening. The remnant low will
continue to lift to the northeast tonight, moving into New England
on Thursday. High pressure will build in behind the departing low
on Friday. A cold front will approach from the west on Sunday,
crossing the area Sunday night into Monday.

&&

.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
Low pressure, the remnants of Ida, moving across NJ attm will
push offshore shortly. Tornado Watch ended at 10 PM. Significant
flooding event in progress will continue overnight. Widespread
Major and some Record floods occurring this evening. Main stem
rivers will be in flood for several more days. Tornado events
have been reported as well with surveys expected Thursday.

Rains end from W to E thru dawn with winds turning N to NW and
gusting 20 to 30 mph.

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH 6 PM THURSDAY/...
High pressure will build into the region on Thursday in the wake of
the departing system. The entire region is expected to dry out
during the morning, with partly to mostly sunny skies during the
afternoon. For this reason, have ended the flash flood watch for the
area at 8 am, as little or no precipitation is expected after that
time.

Main concern is winds, with a stiff north breeze likely for much
of the day, especially near the coast. However, the speed of the
system will likely keep the period of elevated winds rather short,
and the forecast speeds are not overly impressive anyway (10 to 20
mph sustained winds with occasional gusts 25+ mph). Forecast highs
are expected to be in the 70s for most of the area. This will likely
be a welcome reprieve from the frequent bouts of heat we have dealt
with the past few months.

&&

.LONG TERM /THURSDAY NIGHT THROUGH WEDNESDAY/...
No changes to the long term for the afternoon. The previous
discussion remains valid.

Behind the departing remnant surface low that once was Ida, we should
see cooler and drier conditions across our region. The upper level
low will remain nearby Thursday night but should start to lift to
the northeast late Thursday night. The more northerly flow will
allow for cooler air to move across the Mid-Atlantic and we should
have a relatively nice night in store for our area. Temperatures
will be around 5-8 degrees below normal with overnight lows dropping
into the 50s across much of the region. Along the immediate coast,
temps may remain in the lower 60s, while some of the colder spots
in the southern Poconos may actually dip into the upper 40s.

High pressure builds in for Friday and through the holiday weekend.
Daytime temps will generally be in the 70s with a gradual warming
trend from day to day. Overnight lows will also moderate as they
warm from the 50s/low 60s on Friday night to the upper 50s to mid
60s on Saturday and Sunday nights.

A cold front may approach the region late in the weekend, crossing
the region Sunday into Monday. Some showers may accompany the front
as it moves through the area. Conditions should then dry out for
later Monday and much of Tuesday.

&&

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

Overnight...IFR then MVFR in showers and isolated tstms. Rains
end from W to E overnight. Sites return to VFR by dawn. Winds
turn N to NW 10 to 15 knots with G 25 knots overnight.

Thursday...VFR. Mostly SKC. North to northwest winds 10 to 20
kt with gusts 25+ kt possible. Moderate confidence.

Outlook...

Thursday night through Friday...Mainly VFR. North-northwest winds
around 10 to 15 knots. High confidence.

Saturday through Sunday...Mainly VFR. West to southwest winds around
5 to 10 knots. High confidence.

&&

.MARINE...
Low pressure will tracks across the waters overnight, there
should be a relative lull as winds become variable. Then as the
low moves offshore, stiff northerly winds are likely to develop.
Another period of gale-force gusts is expected for the New
Jersey waters during the morning before rapidly diminishing
during the afternoon. Gale warnings have been issued to cover
these threats. Seas will be elevated through Thursday, primarily
between 5 to 8 feet.

Rain and gusty winds diminishing after midnight. Fair weather
Thursday.

Outlook...

Thursday night through Friday... North to northwest winds around 15
to 20 knots will continue to drop overnight into Friday. While a few
gusts around 25 knots can't be ruled out, most gusts look to remain
below 25 knots. Seas will remain elevated into Thursday night and
will gradually drop through the night into early Friday. Some
lingering 5 foot seas are possible, especially across the southern
waters into midday Friday but expect most of the ocean waters to
fall to 3 to 4 feet on Friday.

Friday night through Sunday... Mainly sub-SCA conditions expected.
North to northwest winds around 10 to 15 knots becoming southerly
Saturday night and more southwesterly on Sunday.

Rip Currents...

A MODERATE to HIGH risk for rip currents is expected overnight
and Thursday.

&&

.HYDROLOGY...
Flooding has commenced across the Lehigh Valley, Berks County, the
southern Poconos, Chester County, Delaware County and New Castle
County in northern Delaware. Eventually the rain will pivot across
the entire I95 corridor and into NJ.

Expected rainfall totals increased late last night and this morning.
As a result, crests also increased. The only meaningful changes for
this afternoon lies just north and west of the I95 corridor. The
heaviest rain and associated gradient has been shifted north and
west. This has had an influence on some of the updated afternoon
river forecasts across SE PA and northern NJ, basically dropping some
forecast points by a category (e.g. major to moderate).

Climatologically, August is supposed to be a quiet month in regards
to flooding and severe weather. It was quite the opposite. Parts of
the region got hit with Fred. A larger part of the area got hit with
Henri. In between, rounds of thunderstorms produced flash flooding.
1/3rd of days in August had at least 1 Flash Flood Warning issued.
This has left much of the HSA very wet. Except for SW NJ, all the
other counties we serve are either running above or much above
normal in terms of rainfall. Grounds were saturated leading up this
upcoming event.

Although there have some changes in rainfall amounts, the
Schuylkill, Passaic, and Raritan Rivers are still all forecast to
flood in the moderate to major categories. In addition, the mainstem
Delaware River is still forecast to flood. Although the rain has
shifted north across the Delaware Basin, crests haven't changed
much. In short, instead of the rain falling locally over portions of
the lower Delaware, the rain is now falling to the north, but still
has to flow through lower region forecast points.

Trenton saw flooding in both 2014 and 2018, but during the winter
due to ice jams. The last time Trenton has flooded strictly from a
rain event was in 2011.

Inundation maps have been developed for many forecast points along
the Delaware River and across both the Raritan and Passaic
river basins.

&&

.TIDES/COASTAL FLOODING...
Some issues with coastal flooding along the tidal Delaware
River. These tides have effectively blended with the fresh
water flooding and have produced some minor/moderate tidal
flooding at Philadelphia and Burlington. Levels will drop back
below minor after the high tide after midnight.
