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 26, 9:37 PM EDT, 1 hour 32 minutes earlier.

Area forecast discussion, Jun 26, 9:37 PM EDT, 1 hour 32 minutes before
Area Forecast Discussion
National Weather Service Mount Holly NJ
937 PM EDT Mon Jun 26 2023

.SYNOPSIS...
A low pressure system will continue to track across the Great Lakes,
pulling a cold front toward our area tonight. As this low slides
across our area Tuesday into Wednesday, the cold front will cross
our region. Weak high pressure may settle near our area Thursday and
Friday, then a warm front lifts northward later Saturday followed by
a cold front approaching on Sunday.

&&

.NEAR TERM /THROUGH TUESDAY/...
***Continuing Severe Weather and Flash Flood Threat through at
 least midnight***

940pm: After a short lull in the Severe weather, more severe tstms
have recently developed/moved across Bucks County, PA and into
Mercer NJ. Others near Chester PA, Berks PA and New Castle, DE
too. Finally, a warning for Somerset NJ and surrounding areas.
Numerous Flood advisories and Warnings going as well. Severe
watch has been extended until Midnight. Continue to heed safety
messages on the warnings to protect life and property.

The Storms should eventually start to weaken as they also move
eastward off the coast through the overnight time frame. There
will be some lingering showers overnight though. Also, some
patchy fog may form overnight, especially if there are any
breaks in the clouds.

As an upper-level trough moves into the east Tuesday, surface
low pressure initially over the eastern Great Lakes is forecast
to track east-northeast. The associated diffuse cold front also
continues to move east reaching eastern PA by late day. The
upshot is there will continue to plenty of moisture and lift to
work with so more showers and thunderstorms are expected. For
the morning, think the majority of the activity will be near the
coast with showers/storms then becoming more widespread through
the afternoon over eastern PA, NW NJ through to the urban
corridor. Conditions won't be as favorable for severe weather
compared to today but still think ML CAPEs reach at least
1000-1500 j/kg so some additional severe storms may be possible.
Limiting factors will be the marginal shear and relatively lower
CAPE compared to today that should also be "skinnier" in nature.
Finally, as has been the case the past few days localized flash
flooding will also be a threat near and north of the urban
corridor.

&&

.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/...
The short term period will look to begin Tuesday night with showers
and thunderstorms lingering as a cold front continues to trek
across our area. By Wednesday morning, showers will have tapered
off with the cold front now offshore of the region. Weak high
pressure will look to build behind this front and will build
eastward with time. However, with surface high pressure being
weak with lingering shortwave energy and troughing being
present, the area will look to remain unsettled Wednesday. A
stronger grasp of surface high pressure, though still weak
overall, should take hold Wednesday night and Thursday, finally
allowing our region to see a short break in PoPs.

For Tuesday night, the forecast with carry mainly chance PoPs
starting to taper off by 06z as the cold front pushes eastward.
Model soundings support continued instability into the first half of
the period; will include thunder/thunderstorms with the forecast.
Temperatures and dewpoints will look to remain in the 60s across the
region, some light fog/mist is possible for the early morning hours
after showers have passed.

For Wednesday, the forecast will carry mainly slight chance and
chance PoPs increasing to mainly chance and likely PoPs by the
afternoon. As showers will have access to daytime heating,
instability and thunderstorms remain possible for the
afternoon/evening. Highs in the upper 70s and low 80s can be
expected for the region with dewpoints in the low to mid 60s.

For Wednesday Night, no PoPs are included with the forecast. Lows
primarily in the low to mid 60s can be expected.

For Thursday, no PoPs are included in the forecast except some
slight chance PoPs for mainly northern NJ after 18z. These slight
chance PoPs are included due to the possibility of some
shortwave energy/troughing still holding mainly to our north.
Highs in the low to mid 80s can be expected throughout the
region.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
Ensemble guidance indicates that the upper level trough over the
eastern CONUS/offshore should continue to weaken through Thursday
night. Thereafter, the upper level pattern over the region becomes
more zonal before another upper level trough approaches
Saturday/Sunday.

At the surface level, weak high pressure will be over/just south of
the region Friday as low pressure develops over the Great Lakes
region. This low pressure system will look to have
frontogenesis occuring with it with time, with a warm front
approaching the region Saturday. This warm front will look to
possibly cross the region Saturday night into Sunday, with a
cold front approaching the region then on Sunday. This cold
front may cross the region Sunday night into Monday, but
confidence in this timing right now is very low.

With the synoptic pattern described and still more lingering
shortwave energy persisting towards the beginning of the long
term, the forecast will carry mainly chance PoPs with it
throughout the long term term. The afternoon and evening time
frames will again see the chance for showers each day aided by
daytime heating and instability. Temperatures will look to be
about average to just slightly above average through the period.

&&
