What forecasters said that day

The local office's own words before this special weather statement 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 special weather statement went out at Jun 12, 1:35 PM EDT, 1 hour 38 minutes earlier.

Area forecast discussion, Jun 12, 1:35 PM EDT, 1 hour 38 minutes before
Area Forecast Discussion
National Weather Service Mount Holly NJ
135 PM EDT Mon Jun 12 2023

.SYNOPSIS...
Low pressure tracks across the eastern Great Lakes region
today. An attached warm front will get pulled into our area
today followed by a cold front this evening. Weak high pressure
arrives for Tue before another low and front move in for
Wednesday. High pressure settles in Thursday, but it will be
followed by an unsettled pattern for Friday and into the
weekend.

&&

.NEAR TERM /THROUGH TONIGHT/...
Forecast is on track this afternoon and no adjustments were made
to the hourly grids. SPC has pushed the Slight Risk further
north into the Philadelphia metropolitan area. Taking a look at
the 17z mesoanalysis package, a tongue of instability exists
extending from SE PA and Central New Jersey into Delmarva.
MLCAPE values are around 1000 J/kg with SBCAPE values upwards of
2000+ J/kg over Delmarva and 1000 J/kg over SE PA and Southern
NJ. The latest ACARS sounding from KPHL had around 1500+ J/kg of
SBCAPE and 30 kt of 0-3 km shear. The entire region has a
chance for severe weather today, but the highest probability to
see damaging winds, 1 inch hail, or possibly even a tornado
will be over Delmarva, SE PA, and southern NJ.

The 12z IAD sounding shows a skinny CAPE profile with a PWAT
value around 1.6 inches. This is over the 90th percentile for
mid-June. The freezing level was shown to be around 12,000 feet,
and with a low LCL, we are looking at a warm cloud layer over
10k feet. This does indicate the flooding potential for today,
though storm motion will be relatively quick. However, some of
the short range guidance does show multiple rounds of
showers/thunderstorms for some spots, so we continue to monitor
the flooding threat. While it is true that our area has not seen
much rainfall in over a month, this could also work against us
in terms of runoff. With such a dry surface, most of the rain
may not seep into the surface, similar to what we saw at the end
of April.

Previous full update...

Otherwise, a closed upper low will meander over the Great
Lakes. Surface low pressure will organize and develop over
western New York and western Pennsylvania this morning, and a
cold front will extend out from that low. That low will track
north into Canada, and the cold front extending from that low
will approach later today. A secondary low will form on that
front, and this system will pass through the region, with the
secondary low passing through the Lehigh Valley, southern
Poconos, and northern New Jersey, this evening. High pressure
begins to build in from the west after midnight tonight.

Southerly flow develops ahead of the approaching system, with
south winds increasing to 10 to 15 mph with gusts up to 20 mph
by this afternoon. High temperatures will be some 6 to as much
as 10 degrees cooler than Sunday, generally topping off in the
upper 70s to low 80s. Surface moisture will also increase, with
dew points rising well into the 60s, and to near/around 70 in
Delmarva. As a result, SB CAPE values will rise to 500 to 1000
J/kg across southeast Pennsylvania and New Jersey, and to 1000
to 1500 J/kg across Delmarva. The Storm Prediction Center has
Delmarva and southern New Jersey in a Slight Risk for severe
weather, and a Marginal Risk for southeast Pennsylvania and the
rest of New Jersey. The primary threat will be damaging wind
gusts. Although the surface low will pass well north of
Delmarva, there should be some mid level shortwave energy
passing through Delmarva that will help support thunderstorm
activity.

PWATs will also rise to 1.8 to 2.0 inches. The heaviest rain
will be associated with the passage of the secondary low over
the northern half of the forecast area, with 1 to 2 inches of
rain in the southern Poconos and the Lehigh Valley, while 1/2 to
1 inch of rain will fall down to the I-95 corridor. 1/3 to 1/2
inch of rain is expected for Delmarva and eastern New Jersey. Of
course, locally higher amounts are possible in thunderstorms
and any potential training of thunderstorms. Poor drainage and
localized urban flooding is possible. The Weather Prediction
Center has southeast Pennsylvania and northern New Jersey in a
Marginal Risk for excessive rainfall.

Showers taper off from west to east fairly quickly after
midnight as the cold front departs. West winds develop behind
the front. There may be enough lingering low level moisture for
patchy fog to develop overnight tonight. Lows tonight will be in
the 50s.

&&

.SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/...
The upper low remains across the Great Lakes Tue into Wed and
then crosses the area Wed night. Most of the 00Z op models agree
with the large scale changes. A dry slot rotating ahead of the
low will arrive Tue and will keep dry weather for now, but more
showers rotate in for Tue night into Wed night. A cold front
crosses the area Wed, so this is the period with the highest
pops in the short term with chance pops or the south and
categorical for N NJ and NE PA. Thunderstorms are also possible
with the added instability with the cool temps aloft and the
June warmed lower atmosphere.

&&

.LONG TERM /THURSDAY THROUGH SUNDAY/...
Upper troughing across the Northeast and Middle Atlantic towards the
end of the week will diminish somewhat this weekend (Saturday)
before being replaced by more troughing next week. A pattern which
will promote typical summery unsettled conditions with mostly sunny
and mild days and afternoon shower/tstm chances.

The best chances for showers for Thu/Fri will be for the N/NW areas
as the upper low will be moving off to the NE. After a break Sat
(only slight chances) a more widespread showery pattern is expected
for Sun with 30%/40% pops for the area. Temperatures thru the
period will not swing too far from early June normals with mostly
low/mid 80s for highs and upper 50s to mid 60s for lows. Humidity
levels will be moderate for the most part with an increase noted for
Sunday.

&&

.AVIATION /18Z MONDAY THROUGH SATURDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY and surrounding areas...

Today (through 00z)...Showers and thunderstorms arrive between
18z-22z from west to east, with VSBY restrictions as low as IFR
in the heaviest SHRA/TSRA. S-SE winds 10 to 15 kt with gusts up
to 20 kt. Much stronger wind gusts in any TSRA that pass over a
given terminal. Moderate confidence overall.

Tonight (00Z through 12Z)...Sub-VFR conditions in SHRA/TSRA through
04z. CIGs improve thereafter. Patchy fog possible with sub-VFR
VSBYs. Winds turn W 10 to 15 kt. Moderate confidence.

Outlook...

Tue... Mostly VFR.

Tue night thru Wed night... VFR. Scattered showers/tstms with
  lower CIGS/VSBYS.

Thu/Fri... Mostly VFR. Sct showers/tstms Fri.

&&

.MARINE...
S to SE winds will range from 15 to 20 kt. Occasional gusts up
to 25 kt are possible, but do not think those gusts will be
frequent enough nor widespread enough to justify a Small Craft
Advisory. Seas will build to 2 to 4 ft. A cold front passes
through the waters tonight. Winds turn west behind the front at
10 to 15 kt with gusts up to 20 kt.

VSBY restrictions in areas of fog will develop this morning as
southerly flow will usher a humid airmass over the waters, and areas
fog will persist through tonight. Showers will develop later today,
but more widespread showers and thunderstorms with heavy rain and
gusty winds will develop this afternoon and evening.

Outlook...

sub-SCA conditions expected much of the time. Fair weather Tue
and Thu. Scattered showers/tstms for Wed and Fri. Higher winds
and seas with tstms.

Rip Currents...

South to southeast winds will range from 15 to 20 mph with
gusts up to 25 mph today. This, along with a lingering long
period southeasterly swell will result in a MODERATE risk for
the development of dangerous and life threatening rip currents
at New Jersey and Delaware beaches today.

Winds turn offshore on Tuesday at 10 to 15 mph, though late day
sea breezes are possible. This will result in a LOW risk for
the development of dangerous and life threatening rip currents
at Delaware beaches, but a MODERATE risk for the development of
dangerous and life threatening rip currents at New Jersey
beaches.
