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.

Area forecast discussion, Jul 10, 4:10 PM EDT, 38 minutes before
Area Forecast Discussion
National Weather Service Mount Holly NJ
410 PM EDT Fri Jul 10 2020
.SYNOPSIS...
Tropical storm Fay will continue to move across eastern New Jersey
this evening before exiting to the northeast tonight and early Saturday.
Weak high pressure will be over the area Saturday morning before
a cold front crosses the region Saturday night. Another front will
cross the area Monday. High pressure will build over the area for
the middle of next week.
&&
.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
Tropical Storm Fay was centered about 15 miles east of Ocean City,
New Jersey around 3:00 PM. The center will move northward along the
New Jersey coast into this evening, and through the New York City
metropolitan area and up into southeastern New York and southwestern
New England overnight.
The potential for heavy rain has come to an end in much of eastern
Maryland, central and southern Delaware and far southern New Jersey.
The Flash Flood Watch has been cancelled for those areas. We
continue to expect some heavy rain in the central and northern
portions of our forecast area, so the Flash Flood Watch continues
there. Widespread totals in the 1 to 4 inch range are anticipated
with locally higher amounts. The rain will continue to end gradually
from south to north during the evening and overnight hours as Fay
drifts further to the north.
Winds along parts of the New Jersey coast will continue to gust in
excess of 40 MPH into this evening. Meanwhile, the wind gusts
elsewhere in our area should range generally in the 15 to 25 MPH
range. Wind speeds will likely diminish overnight.
A decrease in cloud cover is expected overnight. However, localized
fog is possible. Low temperatures should favor the upper 60s and
lower 70s.
&&
.SHORT TERM /6 AM SATURDAY MORNING THROUGH 6 PM SATURDAY/...
Saturday looks to be a typical summertime day in our region with
scattered cumulus and the potential for afternoon showers and
thunderstorms. Highs are expected to be mainly in the upper 80s and
lower 90s with a southwest wind around 10 MPH. Conditions will
remain humid.
A mid level short wave trough is expected to approach from the west
on Saturday. Abundant low level moisture will allow mixed layer CAPE
values to rise into the 1500 to 2000 J/Kg range in the afternoon.
The instability along with the short wave should result in the
development of thunderstorms. Much of our region is under a marginal
risk for severe weather.
&&
.LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/...
Tropical storm Fay will have diminished well north of the area by
the start of the long term and a following trough with a surface
cold front will be crossing the Middle Atlantic region Saturday
evening. The scattered showers and tstms will end overnight with
perhaps some patchy fog late at night.
Sunday and Sunday night generally look like fair weather across most
of the region as weak high pressure builds over the area. Some
shortwave energy north of the area may touch off a scattered shower
or tstm across the southern Poconos and perhaps as far south as the
Lehigh Valley. Confidence in these showers occuring is not great, so
we'll just keep slight chc pops in mos areas with some chc pops near
the N/W most edges of the CWA. Above normal temps with upper 80s/low
90s most areas. Dew points mostly in the mid 60s, so humid, but not
excessively so.
Unsettled summerlike conditions are expected early next week with
most days featuring some scattered showers and tstms (mostly)
during the afternoon and early evening hours. Both days will
have very warm conditions with highs 3 to 5 degrees above normal
and humidity values rather humid.
Hot and humid conditions will develop across much of the Middle
Atlantic for the middle of next week with an upper high
pressure strengthening across the Tenn/Ohio Valley areas. Highs
Wed/Thu will be mostly in the low to mid 90s with apparent temps
in the mid 90s Wed and in the 100s on Thu. It could end up
being the warmest day of the summer (Thu) if the present fcst
number hold. Dry conditions are fcst for Wed and this will last
into Thu when a few sct tstms may form during the afternoon.
&&
.AVIATION /20Z FRIDAY THROUGH WEDNESDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY and surrounding areas.
Into this evening...Mainly IFR/MVFR conditions, improving to VFR at
times. Showers with isolated thunder. The rain will be moderate to
heavy at times. Northeast to north wind 10 to 15 knots with gusts of
20 to 25 knots. Medium confidence.
Tonight...MVFR/VFR conditions. Rain showers lifting to the north of
our region. Northwest to west wind less than 10 knots. Medium
confidence.
Saturday...Mainly VFR with a chance of afternoon showers and
thunderstorms. Southwest wind around 10 knots with gusts of 15 to 20
knots. Medium to high confidence.
Outlook...
Sat night thru Tue...VFR most of the time with only a few
scattered showers and tstms mostly during the afternoon and
early evening periods. Lower CIGS/VSBYS with any tstm.
Wed...Mostly VFR.
&&
.MARINE...
Tropical Storm Fay will continue to move slowly northward along the
New Jersey coast into this evening, before lifting into southeastern
New York and southwestern New England overnight.
The Tropical Storm Warning remains in effect. Wave heights on our
ocean waters were mainly in the 6 to 10 foot range this afternoon.
As the tropical storm moves away from our region late tonight and
Saturday, conditions will improve. A south to southwest wind around
10 to 15 knots is anticipated for Saturday. Wave heights are
expected to subside slowly but they may remain around 5 to 6 feet on
our ocean waters for much of the day.
Outlook...
Seas on the ocean will continue to remain choppy Sun thru Tue with
swell conditions expected to keep seas near SCA criteria. Winds
will overall remain below SCA conditions however. Scattered
tstms Sun thru Tue with locally higher winds and seas.
Rip Currents...
Rest of today...High risk will continue.
Saturday...High risk expected.
&&
.TIDES/COASTAL FLOODING...
As Fay departs the area tonight we can expect that the tidal departures
will remain elevated with 'close to minor' tidal flooding possible
in a few areas. Right now, it doesn't appear to be widespread or
significant enough to consider any flags, but we will continue to
monitor overnight.
A southerly flow will develop across the Chesapeake Bay on
Saturday as Fay departs and a cold front approaches. This will
probably cause water levels to become higher than usual, so
we'll monitor this overnight in case any flags or statements
become necessary.
&&

PA (WNG704) remains off the air until further notice due to damage
