What happened

The episode as NWS PHI wrote it up.

A strong cold front moved through the mid-Atlantic late on May 16. Multiple areas of convection developed ahead of the front. With moderate to strong instability and shear, the environment ahead of the front appeared favorable for widespread severe weather. However, a messy convective evolution served to limit the overall threat. The greatest frontal forcing also ultimately tracked further north. However, some storms still became strong to severe and produced a few instances of damaging winds and hail.

What forecasters said that day

The local office's own words before the first event, 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 the first event at May 16, 2:55 PM EST, 2 hours 25 minutes earlier.

Area Forecast Discussion
National Weather Service Mount Holly NJ
355 PM EDT Mon May 16 2022

.SYNOPSIS...
A strong cold front will sweep across the Mid Atlantic today
bringing the threat of severe weather to the region. High
pressure will build in on Tuesday. A weak low may cross the region
on Thursday along a warm front. High pressure will build across
the western Atlantic Friday and into next weekend.

&&

.NEAR TERM /THROUGH TUESDAY/...
***Severe Thunderstorm Watch #229 and Severe Thunderstorm Watch
 #230 in Effect through 8 PM***

Several waves of strong to severe thunderstorms will affect the area
this afternoon into this evening. The first area associated with an
initial short wave is moving across portions of eastern Pennsylvania
this afternoon, and will continue to move to the east across the
rest of eastern Pennsylvania and portions of central and northern
New Jersey through the afternoon hours. CAPE values have increased
to 1000-2000 J/kg, while shear is around 35-45 knots.  While DCAPE
values are not overly high, less than 500 J/kg, damaging winds are
likely with any severe storm, and with freezing levels/wet-bulb zero
heights around 10,000 feet and ample CAPE above the freezing level,
severe hail will also be possible with some storms. As this activity
continues to progress eastward, another short wave/vorticity impulse
will approach the area from the west and the cold front moves into
the area and likely enhance shower and thunderstorm activity across
the southern half of the area later this afternoon into this
evening. The same is true as farther north, with CAPE values at
least 1000-2000 J/kg, while shear around 35-45 knots, and eventhough
DCAPE values are not overly high, less than 500 J/kg, damaging winds
are likely with any severe storm. Freezing levels/wet-bulb zero
heights are around 10,000 feet here as well with ample CAPE above
the freezing level, severe hail will also be possible with some
storms.

Another concern with the showers and thunderstorms will be the
potential for heavy rainfall. PW values are around 1.5 inches, and
if any storms train, a few isolated areas of flash flooding could be
possible. However, since storms will mostly be moving at a fast
enough easterly speed, widespread flash flooding is not expected.
Mainly ponding on roadways and poor drainage areas that fill in
heavy rainfall is expected.

The showers and thunderstorms are expected to move offshore by
sunset and the rest of the overnight will be dry behind the cold
front. Winds will remain a little gusty for a few hours behind the
front for some areas, but wind gusts will diminish overnight.

On Tuesday, temperatures are forecast to be near or slightly above
normal for most places. A dry forecast is expected, although some
afternoon clouds are expected across the area. Winds will become
gusty by the mid to late morning hours and continue into the
afternoon. Wind gusts could reach 20 to 30 mph for some areas.

&&

.SHORT TERM /TUESDAY NIGHT THROUGH WEDNESDAY NIGHT/...
Tuesday night, surface high pressure will approach from the
west with winds rapidly weakening as the PBL decouples. Expect
low temperatures in the mid 40s to lower 50s across the area.

Surface high pressure will move overhead Wednesday with 850 MB
temperatures lowering to around 6 degrees C. This will make
Wednesday the coolest day of the work week with highs mainly in
the upper 60s to low 70s. Clouds will be increasing though as a
shortwave rapidly approaches from the west.

Wednesday night, a warm front will approach the region from the
southwest with a weak surface low forming along the baroclinic
zone. Showers will then move in from the west Wednesday night.
Overall, the track of the surface low appears to be further
north than previously forecast. Expect lows mainly in the 50s
Wednesday night/ Thursday morning.

&&

.LONG TERM /THURSDAY THROUGH MONDAY/...
Most of the overall synoptic pattern in the extended is in
rather good agreement with the GEFS, GEPS, and EPS this morning.
The below normal mid-level heights of Tuesday and Wednesday will
slowly transition to above normal by Friday/ Saturday as the
mid-level ridge amplifies over the western Atlantic. Sunday into
Monday of next week, the sub-tropical ridge will begin to break
down ushering in a break from the very warm temperatures of
Saturday. There does, however, remain substantial variability
in the details of how the evolution of the wave pattern occurs,
and the degree of amplification.

During the day Thursday, the surface warm front will lift north
across the region with showers ongoing initially. As the wave
exits the coast, a brief break in the precipitation is expected
(on the subsident side of the shortwave). However, timing of the
wave remains rather important here though, as a slower
progression would favor another round of showers and
thunderstorms developing Thursday afternoon due to day time
heating. Either way, Thursday doesn't look like a complete
washout, but clouds will be rather widespread with dewpoints
rapidly climbing back towards 60 degrees.

By Friday, temperatures will start to climb with highs in the
mid 80s expected. Dewpoints will also be right back in the mid
60s. The uptick in humidity will be noticeable. On Saturday, the
amplification of the mid-level ridge will take shape with
heights rapidly rising across the region. Expect high
temperatures in the low 90s across the urban corridor. A
surface cold front will then cross the region Sunday with
temperatures falling back towards normal for this time of year.

&&

.AVIATION /20Z MONDAY THROUGH SATURDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.

A line of convection from KRDG to KBGM moving ENE and should
impact Poconos, Lehigh Valley, and northwestern NJ 18Z to 22Z.
More convection is expected from KTTN to KILG and points south
and east from 19Z to 23Z, including KPHL. G50kt possible with
stronger storms. Ceiling and Vsbys will be VFR for entire period
except 2SM and 2kft deck in convection. Surface winds will
become westerly this evening 10 to 20 knots and continue into
Tuesday.

Outlook...

Tuesday night...VFR. West winds 5 to 15 kts. High confidence.

Wednesday...VFR. Northwest winds winds 5 to 15 kts with gusts
up to 20 kts. High confidence.

Wednesday night and Thursday...Clouds increasing from the west.
VFR initially then slowly lowering to MVFR/ IFR as showers
spread over the region. Southerly winds backing from the
southeast 5 to 10 kts. A slow recovery to VFR possible Thursday
afternoon. Moderate confidence on overall pattern, but low
confidence on where exactly the showers set up.

Friday...Mainly VFR. South winds 5 to 15 kts. Moderate
confidence.

&&

.MARINE...
Late this afternoon through Tonight...Occasional gusts around 25
knots will continue this afternoon into this evening ahead of an
approaching cold front. Showers and thunderstorms will accompany
this front, which could produce winds in excess of 34 knots. Once
the thunderstorms move through the area, wind gusts will diminish
overnight.

Tuesday...Winds are expected to remain below advisory levels as an
inversion should keep winds 20 knots or less.

Outlook...

Tuesday night...Sub-SCA conditions. West winds around 15 kts
gusting up to 20 kts. Seas 3 to 4 feet.

Wednesday through Friday...Winds and seas are expected to remain
below SCA criteria.
