The episode as NWS OKX wrote it up.
Deep layered troughing approached the area from the west along with a cold front at the surface. The area was able to destabilize ahead of the cold front to between 1000 and 1500 j/kg of MLCAPE. The front sparked showers and thunderstorms and with 30 to 40 kt of Effective Bulk Shear available, many of the storms became strong to severe. Single cells and multi-cell clusters were able to produce damaging wind gusts in northeast NJ.

NWS New York, NY wrote its last area forecast discussion before the first event at Jul 3, 2:28 PM EST, 2 hours 37 minutes earlier.
Area Forecast Discussion National Weather Service New York NY 328 PM EDT Thu Jul 3 2025 .SYNOPSIS... A cold front approaches and passes this afternoon into evening. High pressure builds in behind the front tonight through Friday night. High pressure remains in control through Sunday. A cold front approaches from the Great Lakes on Monday, passing slowly across the area Tuesday or even stalling in close proximity into midweek. && .NEAR TERM /UNTIL 6 AM FRIDAY MORNING/... *Severe Thunderstorm Watch in effect for the entire area through 10PM. The environment this afternoon remains primed for the potential for severe thunderstorms. A well-mixed lower atmosphere under mostly clear skies is allowing for ample surface heating. While the deep mixing is allowing for a localized lowering of surface moisture, a subtle shift in the wind from a WNW to a WSW flow later this afternoon should allow for dew points to increase a few degrees. Ample cool air aloft with the approach of an upper level trough and a strong mid-level shortwave is allowing for both moderate instability and an increasing source of synoptic lift. Relatively strong mid and upper level flow is allowing for shear on the order of 30-40kt this afternoon. The combination of sufficient shear, moderate instability, and strong synoptic forcing brings the potential for severe thunderstorms this afternoon. A relatively dry BL and mid-levels means that as storms develop or approach from the west, strong to damaging wind gusts may develop as rain-cooled air descends from any storm. This remains the primary threat for any storms this afternoon and evening with a secondary threat of large hail and heavy rainfall. Despite heavy rainfall in thunderstorms, the speed at which they will be moving should limit hydrologic issues and any flooding threat should be fairly localized outside of any training storms. As the sun sets and surface heating diminishes, the intensity and ability for storms to maintain themselves should fairly quickly weaken. The mid-level shortwave forcing the convection this afternoon slides overhead tonight pushing a surface cold front through. Skies will become generally clear with NW flow brining in drier air. Lows tonight will be in the 60s for much of the area with some spots in the Lower Hudson Valley may drop into the upper 50s. && .SHORT TERM /6 AM FRIDAY MORNING THROUGH FRIDAY NIGHT/... *Ideal conditions are expected for Independence Day celebrations. The upper-level trough axis shifts east on Friday and completely exits east by Friday night. At the same time, an upper-level ridge builds in from the west. At the surface, high pressure builds in from the west Friday into Friday night, passing east offshore. As high pressure builds in, skies should remain mostly clear with ample surface heating. The upper level trough still generally over the area will limit the rising of surface temperatures, though highs will still be seasonable, generally in the low to middle 80s. Long Island and the NYC Metro may actually rise into the upper 80s under a light NW flow. Lows Friday night will be in the 60s, with interior areas possibly dropping into the upper 50s. && .LONG TERM /SATURDAY THROUGH THURSDAY/... Key Points: * A predominately dry weekend with increasing warmth and humidity through Monday. * Unsettled conditions return Monday through Wednesday, with shower/thunderstorm chances each day. The NBM was largely followed with this update with no major changes. Good model agreement on the synoptic pattern to start the period, with upper ridging/rising heights Saturday and Sunday. Attendant southerly flow with sfc high pressure to the southwest will continue to advect a more warm and humid airmass into the region, peaking on Monday (h85 temperatures 16-18C), which would yield sfc temperatures in the low 90s, especially away from coastal areas. There is some question as to the amount of cloud cover that will be present, which may inhibit heating a bit and thus the high temperatures. Those clouds appear to be in association with a stream of moisture advecting north into the area from an upper low off the mid-atlantic coast. Guidance is more varied on the evolution of this system, and its possible interaction with an upper shortwave and cold front moving in from the Great Lakes region on Tuesday. A period of showers and thunderstorms is thus likely Tuesday afternoon, with the frontal boundary stalling south of the area into Wednesday. && .AVIATION /20Z THURSDAY THROUGH TUESDAY/... A cold front approaches this afternoon and moves across the area this evening. Mainly VFR. TSRA possible late afternoon and early evening, mainly 20Z to 00Z Fri. Any TSRA could produce brief IFR conditions and could contain strong, gusty winds along with a wind shift to the NW- N. A few storms could contain wind gusts around 50 kt. A few showers may linger an hour or two behind the cold front passage. W-WSW winds this afternoon away from the immediate coastal terminals with wind speeds around 10 kt and gusts up to 20 kt. SSW winds 10- 13 kt expected at KJFK, KISP, KBDR, and KGON this afternoon. Winds may start to shift towards the W where the sea breeze has occurred late in the afternoon before becoming NW this evening with the cold front passage. Wind speeds weaken overnight and become light and variable at most sites. NW winds increase Friday morning, becoming around 10 kt in the afternoon. ...NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty... Wind direction may vary from 230 to 270 at KEWR and KTEB through 23z. Sea breeze could briefly pass across KLGA 21-22z with winds varying between 210-230. Timing of TSRA may be off by an hour or two. A few storms may contain gusts around 50 kt along with a wind shift to the NW-N possible with any TSRA. A few showers may linger after 00z, but should have limited impact on ceilings and visibilities. .OUTLOOK FOR 18Z FRIDAY THROUGH MONDAY... Friday Afternoon: VFR. Occasional NW wind gusts G15-18 kt possible. Friday night through Saturday night: VFR. Sunday: VFR. SSW gusts up to 20 kt possible Sunday afternoon. Monday-Tuesday: Mainly VFR. Chance of afternoon and evening showers and thunderstorms. Detailed information, including hourly TAF wind component forecasts, can be found at: https:/www.weather.gov/zny/n90 && .MARINE... Sub-SCA conditions are expected on all waters under a weak pressure gradient through Friday night. Tstms may pose a hazard of strong winds, lightning, heavy rain, and locally rough seas this afternoon and this evening. Sub-SCA conditions are expected this weekend into early next week. Southerly flow on the ocean waters Sunday into Monday will feature G15-20kt with seas generally around 3 ft, possibly as 4 ft late Monday. && .HYDROLOGY... No widespread hydrologic impacts anticipated through the middle of next week. && .TIDES/COASTAL FLOODING... A lingering southerly swell of 2-3 ft 6-7s will produce a moderate rip current risk on Thursday, and low on Friday. Surf looks to be around 2-3 ft Thursday and around 2 ft on Friday. && .OKX WATCHES/WARNINGS/ADVISORIES... CT...None. NY...None. NJ...None.
