What happened
The episode as NWS PHI wrote it up.
A cold front and associated weak area of surface low pressure approached the mid-Atlantic on June 14. A seasonably warm air mass was present ahead of the front, allowing a moderate amount of instability to build over the mid-Atlantic. Moderate to strong wind shear was also present thanks to the presence of a robust upper level disturbance approaching the region. This disturbance, along with the front, provided sufficient forcing for scattered to widespread convection to develop in the interior mid-Atlantic and propagate towards the coast. Some storms became strong to severe in the rather favorable convective environment, posing a primary risk of damaging winds along with some hail. Convection also continued well into the overnight over portions of the area thanks to the good shear and forcing, with convection eventually moving offshore in the pre-dawn hours of the 15th.

Area forecast discussion, Jun 14, 1:29 PM EST, 2 hours 36 minutes before
Area Forecast Discussion National Weather Service Mount Holly NJ 229 PM EDT Mon Jun 14 2021 .SYNOPSIS... Low pressure over eastern Ontario will progress to the east with its associated cold front forecast to pass through our region late tonight into early Tuesday morning. The low should then move northeastward towards Canada's Maritime Provinces on Tuesday and Tuesday night. A secondary cold front will on Wednesday evening with high pressure arriving in its wake for Thursday and Friday. Another cold front is expected to approach from the northwest on Saturday and it should pass through our region on Saturday night and could stall just to our south into Sunday. && .NEAR TERM /THROUGH TUESDAY/... 215 pm update: Grids have been updated for Severe Thunderstorm Watch 270, in effect through 9 pm EDT for all of eastern PA, northern and central NJ, and New Castle County in DE. Damaging winds are the main threat, but marginally severe hail cannot be ruled out. Main timing for our CWA looks to be 4 pm onward from north to south. We should see clearing from SW-NE through this afternoon, opening the door for diurnal destabilization with portions of the area warming up to near 80 degrees and MLCAPE values likely exceeding 1500 J/kg (in areas that see clearing). The primary synoptic forcing, associated with an amplifying shortwave and surface cold front, will likely remain upstream of our area through at least early afternoon so confidence in convective coverage for this period is relatively low. That being said, any storms that do form will have the potential to produce gusty winds, small hail, and brief heavy rainfall given the aforementioned instability, 45kts of bulk shear, and dewpoints in the mid 60s (although PWATs will remain a fairly meager 1.3 inches or so). Latest guidance along with the convection developing over western PA this morning, lend more confidence to a sped up time frame on the potential for severe weather. The latest CAMs are showing storms firing up to our west and moving into our area later this afternoon and continuing into this evening as the front crosses the region. They largely depict one or more linear convective features moving towards the area and this evolution seems reasonable given the strong mid-lvl flow and associated shear (500mb winds, and 0-6km shear will be in the 90-95th percentile for mid June) which should help support convective organization and maintenance. Although we may see a shallow nocturnal surface inversion form, reasonably steep lapse rates above this shallow layer should support wind gusts reaching the surface in any well- organized convection. SPC highlights this potential for damaging winds by placing the majority of our area in a slight risk for severe weather today (mostly for the evening into the early overnight period). Given the fast propagation of the system, convective mode, and strong flow aloft, damaging winds look to be the primary threat although hail will also be possible. The tornado threat will be limited by the weak low-lvl wind fields (the wind field is very "mid-lvl heavy" in this event). Heavy rain is certainly a concern with any stronger convection with some signal for 1-2+ inch an hour rates, however suspect that the quick system motion will make the hydro threat secondary to the wind threat. The main forecast uncertainties are both the timing of the latter round of convection, and also its spatial coverage. For example, the latest CAMS have a spread of nearly 4 hours in timing the QLCS passage which is not particularly surprising given that the quick system motion, combined with the potential for convectively-driven propagation effects related to cold pools are a recipe for timing discrepancies. Additionally the timing situation is further complicated by the fact that several CAMS depict separate northern and southern linear segments developing, while other CAMS show only a more consolidated southern segment impacting our area. Generally suspect that the most likely period for a potential QLCS would be 00- 06Z with the best chance of severe winds being roughly TTN southward, however if the northern segment is able to get going the risk could both extend further northward and also begin earlier. For Tuesday, the axis of a short wave rotating around the trough is forecast to pass overhead early on Tuesday afternoon. As a result, we will keep a chance of showers in the forecast. There will continue to be some weak instability at that time so we will also mention a slight chance of thunder. && .SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/... The period from Tuesday night through Thursday will feature a fairly sharp mid level trough extending southward from Quebec over the eastern states. The main axis of this trough looks to pass through by Tuesday night resulting in mainly dry weather for this time period. Tuesday night into Wednesday, the region will be situated between high pressure over the midwest and low pressure over Atlantic Canada. This will set up a dry air advection pattern with lowering dew points and skies that will generally be mainly clear to partly cloudy. Lows Tuesday night will be mainly in the 50s to around 60 with highs Wednesday mainly in the 70s to near 80. High pressure builds in for Wednesday night and Thursday bringing continuing mainly clear skies with temperatures a little on the cool side for this time of year as lows will be mainly in the 50s with highs mainly in the 70s. && .LONG TERM /THURSDAY NIGHT THROUGH MONDAY/... The mid level trough moves out to sea Thursday night with some ridging from the southwest and west arriving overhead on Friday. Another mid level trough is expected to progress from Ontario and the Great Lakes through the northeastern states over the weekend. At the surface, high pressure is forecast to slide off the coast Thursday night into Friday. It should remain dry Friday with readings likely getting into the lower and middle 80s at most locations as the return flow on the back side of the high begins to bring warmer air into our region. A cold front associated with the weekend's mid level trough is anticipated to approach from the northwest on Saturday before passing through our region on Saturday night. As a result, we will mention a chance of showers and thunderstorms at that time for Saturday afternoon/evening. The front may stall near or just south of the region Sunday into Monday but forecast details remain uncertain at this time. Will keep in at least a slight chance of showers across most of the region for both days. && .AVIATION /19Z MONDAY THROUGH SATURDAY/... The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas. Through this afternoon...Mainly VFR conditions expected with MVFR cigs scattering out across the region. Isolated thunderstorms remain possible with increasing chances from northwest to southeast from 21Z onward. SW winds 5-10kts. High confidence with lower confidence in timing and coverage of thunderstorms. Tonight... Thunderstorms will progress eastward later this afternoon into this evening with the potential for some of the to become strong to severe, and continuing through the early overnight period. Best timing is generally between 23Z- 05Z, before the storms exit to the east of the terminals. Strong, gusty winds with the potential for small hail through tonight along with low MVFR to IFR cigs and vis. Conditions remain low MVFR to IFR (possibly LIFR at times) behind the storms and continuing through the rest of the night. Southwest winds ahead of the storms may become slightly more southerly before becoming light and variable overnight. Winds will start to trend more to the northwest towards morning. Moderate confidence in the overall forecast, low confidence in timing/coverage of storms. Tuesday...MVFR/IFR conditions expected to continue through 14-15Z before improvement to VFR starts to occur. Northwest winds around 5 to 10 knots int he morning will increase to 10 to 15 knots with gusts around 20 knots through the afternoon. Slight chance for some showers or thunderstorms but confidence to low to include even a VC at this time. Moderate confidence. Outlook... Wednesday...VFR. Northwest wind around 10 knots. High confidence. Thursday...VFR. Northwest wind 5 to 10 knots. High confidence. Friday...VFR. Southwest wind around 10 knots. High confidence. Saturday...Mainly VFR except restrictions possible in late day showers/storms. SW winds 10 to 15 knots. Moderate confidence. && .MARINE... Sub-SCA conditions will prevail through Monday night with seas running 2-3 ft and southerly winds around 10-15kts. There will be potential for thunderstorms with locally strong winds tonight over all waters. Outlook... Tuesday through Friday...No marine headlines are anticipated. Saturday...Southwest winds will increase and could get near SCA levels by late day. Rip currents... The risk of dangerous rip currents is expected to remain borderline Low-Moderate through Tuesday given 2ft breakers, and medium-period low amplitude shore-perpendicular easterly swell For now will go LOW risk for today (Monday) and MODERATE risk for Tuesday, but in reality both days should feature similar near-shore conditions. && .PHI WATCHES/WARNINGS/ADVISORIES...
