The episode as NWS PHI wrote it up.
Following a more than two week stretch of dry weather, a cold front approached the mid-Atlantic on May 26. Ahead of the front, an unseasonably hot and humid air mass developed, with high temperatures near to above 90 degrees in much of the region. This contributed to strong instability, while wind shear was more moderate. Multiple rounds of convection affected the region, triggered by a pre-frontal trough and a couple of upper level impulses ahead of the front. A fairly widespread severe weather event resulted, with damaging winds by far the most widespread hazard. Numerous instances of downed trees and power lines and some property damage were reported. Thunderstorms during the evening hours were also prolific lightning producers. The final round of storms finally moved offshore close to midnight after several hours of severe weather in the region.
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 26, 2:46 PM EST, 25 minutes earlier.
Area Forecast Discussion
National Weather Service Mount Holly NJ
346 PM EDT Wed May 26 2021
.SYNOPSIS...
A cold front front will move across the area this evening and
overnight, before settling to our south on Thursday. This front
will begin to lift back northward Thursday night into Friday,
but likely not make it fully into the area. An area of low
pressure will move along this boundary from the Ohio River
Valley, then across the southern Mid Atlantic to our south on
Friday into Friday night. Additional low pressure systems may
form along the boundary to our south over the weekend. High
pressure briefly builds across the are late Monday into Tuesday.
&&
.NEAR TERM /THROUGH THURSDAY/...
Severe Thunderstorm Watch #206 is now in effect for the entire
forecast area.
As of 18Z the primary area of low pressure was located well to
our north over eastern Canada, with a cold front extending SW of
it... currently in the vicinity of the central Great Lakes.
Downstream of this feature a couple of more subtle sfc.troughs
were evident in latest analysis, with the more prototypical
synoptic prefrontal trough over far western PA/eastern OH, and a
more thermally-induced lee-side trough over central PA. These
troughs have been the primary focus for convection so far this
afternoon, and numerous thunderstorms... some of which are
strong-severe are currently being observed over central PA/NY.
A warm and humid airmass is currently in place over our area,
with surface temperatures in the upper 80s to lower 90s and
dewpoints around 70. As evidenced by the fairly poor mixing and
lack of cumulus, a cap is currently in place over our area.
However, all indications are this cap will begin to erode as we
head into the mid afternoon and thus expect upstream convection
to largely maintain itself as it moves towards our area.
The convective parameter space this afternoon will be
characterized by roughly 1000-1500 J/kg of MLCAPE with 0-3/0-6
shear values largely 20-30kts. Severe winds remain the primary
convective hazard with steep low-lvl lapse rates/Inverted V
profiles and DCAPE values around 1000 J/kg. Think that most will
be of the individual cell downburst variety but multicell
clusters organized via individual cell cold pools are also
possible. Small hail is possible, but higher than climo WBZ0
heights along with modest mid-lvl lapse rates should preclude
widespread large hail. Think the best chance of severe weather
will be with the first round of convection associated with the
lee-side trough mid-late afternoon, as although coverage may
increase into the evening we should get progressively more
stable.
A second round of convection associated with the prefrontal
trough and associated mid-lvl shortwave looks likely to move
into the area this evening. Eventually the cold front itself
approaches our area overnight, however, it may struggle to make
much southward progress. Consequently (due to the lack of
notable dry air advection) there is some potential for patchy
fog (particularly in areas that receive rain) but do not have
high confidence in this.
The front will push south, while also washing out, on Thursday
leaving us in a fairly dry post frontal airmass. Although
temperatures will only be a bit cooler than today (largely low
to mid 80s) with dewpoints dropping to near 50 it should feel
more comfortable. Additionally with mostly sunny skies it will
be a nice break between systems.
&&
.SHORT TERM /THURSDAY NIGHT THROUGH FRIDAY NIGHT/...
The short and long term will focus on the period of unsettled
weather with much needed rainfall late in the week into the
weekend, then drier conditions early next week for the long term
period.
The frontal boundary that settles well to our south through
Thursday, begins to lift back northward Thursday night into
Friday. However, the front will likely not make it fully into
the area, and get hung up near the mouth of the Chesapeake Bay
area, while an area of low pressure moves along the portion of
the front that extend into the Ohio River Valley. A secondary
low may form near North Carolina/Virginia area by Friday, before
it takes over as the main low as it moves offshore, pulling the
front offshore as well. Friday into Friday night has the best
chance of rainfall on the northern side of the low pressure that
will be approaching the area from the Ohio River Valley along
the boundary located to our south. This time period has the best
lift/moisture combination associated with surface features and
short wave/vorticity impulses aloft. Mean rainfall amounts
average close to one inch during the Friday into Friday night
period; this will be a much needed rainfall event since we have
not had a widespread accumulating rainfall in over two weeks.
&&
.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
The aforementioned low will then move to the northeast, before
additional low pressure forms along the front and moves offshore
of the Mid Atlantic over the weekend. There will be a chance of
showers through the weekend with the potential for several
short wave/vorticity impulses to accompany the low pressure
systems that are forecast to move near the area. There are some
differences with the medium range model guidance in the
placement and strength of any additional low pressure systems
that form on the front over the weekend as it stall out offshore
of the east coast. So we will maintain a chance of showers
through the weekend, especially closer to the coast.
As we begin the work week next week, high pressure will begin
to approach the Mid Atlantic region Monday, before building
fully across the area Monday night into Tuesday. This will
provide a return to dry weather for the beginning of the week.
By Wednesday of next week, there are indications that a warm
front will begin to lift back across the area, which could bring
another round of unsettled weather to the forecast.
&&
.AVIATION /19Z WEDNESDAY THROUGH MONDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY and surrounding areas.
Rest of Today...Prevailing VFR however temporary flight
restrictions in SHRA/TSRA will be possible... particularly after
21Z. Strong winds and small hail will also be possible in these
storms. Winds largely out of the SW around 10kts Outside of
storms.SHRA/TSRA will result in brief sub- VFR conditions,
mainly at terminals along and west of I-95. The stronger storms
will be capable of small hail and strong thunderstorm wind
gusts. SW winds less than 10 kt. High confidence overall, low
confidence on timing of SHRA/TSRA.
Tonight...SHRA/TSRA lingering until midnight or so. A brief period
of MVFR CIGs possible immediately following the storms,
otherwise, VFR thereafter. W-SW winds less than 10 kt, then
shifting light W-NW towards Thursday morning. Moderate
confidence.
Thursday... VFR with Northwest winds around 10 knots. High
confidence.
Outlook...
Thursday night...VFR conditions expected. Northwest winds early
shift to northeast overnight. High confidence.
Friday-Friday night...Conditions lower to MVFR, then IFR
through the day Friday into Friday night with a period of
rainfall expected. East to northeast winds 5-10 knots,
increasing to 10-15 knots with gusts 15-25 knots possible.
Moderate confidence.
Saturday-Sunday...IFR conditions could improve to MVFR early on
Saturday, then remain across the area through Sunday. Northeast
winds 5-10 knots, with gusts 15-20 knots possible. Moderate
confidence.
Sunday night-Monday...Conditions expected to improve to VFR by
Sunday night and remain through Monday. Northeast winds 5-10
knots. Moderate confidence.
&&
.MARINE...
Marginal SCA conditions are expected for the ocean waters
through early evening with wind gusts around 25kts and seas
4-5ft. Otherwise Sub-SCA conditions are expected to
prevail through Thursday with seas decreasing to around 3ft and
wind gusts only 10-15kts. Thunderstorms will gusty winds and
small hail will be possible late this afternoon into the
evening before activity diminishes overnight.
Outlook...
Thursday night...Conditions expected to remain below advisory levels
through Thursday night.
Friday-Sunday night...Winds and waves are expected to return to
Small Craft Advisory levels during the day Friday, then remain
elevated through the weekend. Winds could approach gale force Friday
night into Saturday morning.
Monday...Winds likely lower below advisory levels Monday, but seas
could remain elevated for a period during the day.
Rip currents...
There is a MODERATE risk for the development of dangerous rip
currents at the ocean beaches today due to a pronounced south to
southwest wind.
Another period of elevated rip current risk looks likely this
weekend as onshore flow/surf heights increase.
