EF4166 to 200 mph
Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.
EF5over 200 mph
Incredible damage. Strong frame houses swept off their foundations, car-sized missiles thrown more than 100 meters, steel-reinforced concrete badly damaged, high-rise buildings deformed.
Unrated
The survey recorded a tornado but could not put a number on it, most often because it crossed open country and damaged nothing a rating can be read from.

What the Weather Service recorded
A strong shortwave trough moved east-southeastward out of the Great Lakes region on July 29. An associated, strengthening surface low also tracked out of the Great Lakes and into upstate New York. A warm front associated with this low moved through most of New Jersey and eastern Pennsylvania during the late morning and early afternoon hours. This front, combined with the remains of widespread convection to the west from the previous overnight and morning hours, brought significant cloud cover to the eastern mid-Atlantic for much of the day on the 29th. This was mainly in the form of mid and high level cloud cover, however, and temperatures still warmed to near seasonal levels behind the warm front, allowing moderate to strong instability to build. Meanwhile, the robust surface and upper level disturbances approaching the region brought both strong forcing and unseasonably strong wind shear. By mid-afternoon, an unusually favorable convective environment existed over eastern Pennsylvania and New Jersey.||The result of this environment was a rare tornado outbreak across the area. Initially, during the mid-afternoon hours, mixed convective modes over east-central Pennsylvania produced a couple instances of damaging wind and brief tornadoes as storms attempted to overcome cloud cover and some light stratiform rain in the area. With time, as storms moved into better instability and a less contaminated environment over far eastern Pennsylvania and New Jersey, they took on more supercellular structures. Multiple cyclic supercells would go on to produce several tornadoes, three of them strong (EF2+) over eastern Pennsylvania and New Jersey. Convection persisted past the sunset hour with little to no loss in intensity due to the strong forcing. The only thing that put an end to the outbreak was the coastline, as storms moved offshore towards 9 to 10PM local time. Even offshore, one supercell continued to exhibit strong rotation and likely produced a strong waterspout for tens of miles over the Atlantic.||Fortunately, and miraculously, no serious injuries or loss of life occurred as a result of this outbreak. With the passage of a cold front late on the evening of the 29th, cooler, drier, and much less active weather would grace the region for several days as clean-up efforts began.
The tornado estimated to have touched down in the New Jersey pine barrens over Burlington County moved into Ocean County, where damage was first observed. The bulk of the damage consisted of large snapped and uprooted pine and spruce |trees with a few red maple trees. Some of the heaviest damage occurred on Old|Cedar Bridge Rd near the Cedar Bridge Tavern Historic Site. The |tornado crossed Route 72 before moving through over a mile of |inaccessible forest land. Tree damage was found again along Jones |Rd. From there the tornado moved into the Wells Mills area where |the path of tree damage continued. A number of snapped trees and |large limbs were found in the area of Wells Mills County Park. The|tornado path appeared to end a few hundred yards east of this |location. The degree of tree damage along the middle portion of |the track was consistent with a higher end EF1 tornado.
The same supercell which produced a tornado in the New Jersey |Pine Barrens cycled and produced another tornado in far eastern |Ocean County. The tornado touched down near the immediate western |shore of Barnegat Bay. At least one building near Bay Beach off |Bayshore Dr sustained roofing damage. The tornado then moved over |Barnegat Bay as a waterspout. It came ashore in the area of High |Bar Harbor in Long Beach Twp.||The most severe damage was noted to a house on the corner of |Antioch Rd and Arnold Blvd. This house was facing west-southwest, |and had its entire roof structure lifted off and tossed one to two|houses to the east. The house walls remained standing but most of|the doors and windows on the east and west sides of the house |were completely blown out, with significant damage to the inside |of the house. A two- by-four from an adjacent house impaled the |wall on the west side of the house. Eight people were in the house|at the time the tornado hit, but they were able to take shelter |in an interior closet, with only minor injuries sustained. In |addition, on the north side of the house, a car in the driveway |was pushed sideways several feet and their boat flipped into their|neighbor's boat. The boat's trailer was tossed about 50 feet into|a house just to the east. The degree and orientation of damage |was consistent with tornadic winds of 115 to 120 mph, which is EF2|intensity.||Continuing east-northeast, about a dozen homes on the south side |of Arnold Blvd sustained significant uplift of roof material, |siding damage or removal, collapse of porch, patio, and sunroom |structures, and blown out windows. Several large trees were |uprooted and lay pointing to the east-northeast, as well as downed|power poles. ||The tornado moved east or slightly north of east from Arnold |Blvd, over an open salt marsh, before intersecting a few houses on|the corner of Collier Rd and Sunset Blvd. The most significant |damage was to a house on the northwest corner of Collier and |Sunset, which sustained siding damage, partial roof removal, |blowout of the storm surge walls on the basement level of the |elevated structure, and a large tree uprooted and laying to the |east-northeast. Power poles and large trees were downed on Sunset |Blvd, adjacent to the High Bar Harbor Yacht Club. There was damage|to several boats in the yacht club marina, but this was mainly |due to lofted debris being tossed into the marina. The circulation|then moved into the cove east of the marina. However, no further |significant damage was noted on the east side of the cover in |Barnegat Light, indicating the tornado had likely lifted. This is |corroborated by radar data which showed a weakening of the |circulation and a likely dissipation before it crossed into the |open Atlantic.

Area forecast discussion, Jul 29, 8:59 PM EDT, 4 minutes before
Area Forecast Discussion National Weather Service Mount Holly NJ 859 PM EDT Thu Jul 29 2021 .SYNOPSIS... A warm front will lift north of the area this evening before a cold front moves across the area tonight. High pressure located across the Mid West on Friday will build toward the east coast on Saturday. Another cold front is forecast to move across the area later Sunday into Sunday night. High pressure may briefly affect the area before an area of low pressure lifts north offshore of the east coast on Tuesday. The frontal boundary to our south may lift northward and affect the area for the middle to end of next week. && .NEAR TERM /UNTIL 6 AM FRIDAY MORNING/... HAve extended the tornado watch through 10 PM for Monmouth and Ocean Counties to account for the severe and tornado warned storms to move off the coast. The warm front is now north of our region. We could still see thunderstorms from the line currently over central NY, but high res models are consistent in showing that line weakening as it gets closer to our region, so will keep the chance for thunderstorms in the forecast, but do expect that the severe risk should decrease once the cluster of storms over central/South Jersey gets off the coast. As the storms clear the coast, surface low pressure will be located near the NY/Canada border and be dragging a surface cold front through the area. Winds will slowly turn from the northwest through the night with skies slowly clearing from the west. && .SHORT TERM /6 AM FRIDAY MORNING THROUGH FRIDAY NIGHT/... Surface low pressure moves off to the northeast with its attendant cold front offshore by Friday morning. With the front offshore, the flow across the region will turn to the west and settle out of the northwest. Winds may become gusty through the afternoon, with gusts around 25 mph or so. Skies will be relatively clear through the day and with dew points dropping down into the 50s (potentially 40s in spots) it will feel nice and dry and pretty comfortable for late July. The cooler air being drawn into our region will be slightly below normal with highs into the 70s through the southern Poconos, northwest New Jersey and the Lehigh Valley and low to mid 80s through the rest of the region. Depending on how far offshore the front moves, we could see some temps remaining in the upper 80s for a while across southern Delaware and nearby eastern Maryland. Friday night will be cold when compared to what we typically see in late July. The clear skies will help with radiative cooling and with the winds dropping off overnight, we should see things drop off decently overnight. Overnight lows will be a chilly upper 40s to low 50s across the northern zones through the Lehigh Valley and into portions of central New Jersey. Around the urban corridor and through Delaware, Maryland, and southern New Jersey, temperatures will be in the mid 50s to lower 60s. && .LONG TERM /SATURDAY THROUGH THURSDAY/... The first half of the weekend is expected to be quiet, before the potential for unsettle weather returns for the end of the weekend through much of next week. On Saturday, high pressure to the west will control the weather, providing a dry forecast through Saturday night. Below normal temperatures are expected through Saturday night as well. On Sunday, active weather could once again return to the forecast. An area of low pressure is forecast to move across southeast Canada and bring a frontal boundary/surface trough across the east coast Sunday into Sunday night. Meanwhile, an area o flow pressure may form along the frontal boundary to our south and move to the northeast offshore of the Mid Atlantic coast. There will be a chance of showers and thunderstorms through the day Sunday, most likely associated with the approaching frontal boundary coming from the west. The low off the coast may remain far enough offshore to not bring any impacts to the area. On Monday, our area will be in between the departing system from the weekend, and another potential coastal low that is expected Tuesday. Therefore dry weather is expected on Monday. However, on Tuesday, another coastal low is forecast to develop to our south and may end up inching close enough to the coast to bring a chance of showers and thunderstorms to the area. As we go through the second half of the week, unsettled weather is possible to continue for Wednesday and Thursday as the front to the south may begin moving back northward and into the area while a couple of low pressure systems may develop and move near the area as well. Temperatures for the long term period are expected to be near or slightly below normal for the weekend into much of next week. && .AVIATION /01Z FRIDAY THROUGH TUESDAY/... The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas. Tonight...Showers and thunderstorms will move the terminals from west to east this afternoon, ending between 22Z-03Z. Conditions will drop to MVFR/IFR in and around any storms. Winds may gust in excess of 30 knots in and near thunderstorms. Conditions are expected to be MVFR for a period of time behind the storms before returning to VFR by late tonight. South to southwest winds around 10 to 15 knots, becoming northwest around 5 to 10 knots overnight. Moderate confidence overall with low confidence in thunderstorm timing. Friday...Mainly VFR. Northwest winds around 10 to 15 knots with gusts up to 25 knots possible in the afternoon. High confidence. Outlook... Saturday-Saturday night...VFR. Northwest winds 5-10 mph during the day, light and variable overnight. Sunday...Mostly VFR. Chance of showers and thunderstorms which may temporarily lead to lower conditions. Southwest winds 5-10 knots, gusts 15-20 knots possible. Sunday night...Chance for conditions to lower below VFR overnight. South winds early, becoming northwest overnight. Monday-Monday night...Mostly VFR expected. Northwest winds 5-10 knots during the day, light and variable overnight. Tuesday-Tuesday night...Mostly VFR. Chance of showers and thunderstorms which may temporarily lead to lower conditions. Northwest winds 5-10 knots during the day, light and variable overnight. && .MARINE... SCA remain up for the ocean waters through midnight tonight. Winds will gusts around 25 knots on the ocean in response to a tightening pressure gradient. Winds will start to drop off tonight. Seas around 3 to 4 feet. Mainly sub-SCA conditions are expected for Friday. Northwest winds around 10 to 15 knots with gusts around 20 knots. Seas will remain around 3 to 4 feet. A few gusts may near 25 knots late afternoon into Friday night in the strong northwest flow, especially in the coastal waters off of northern and central New Jersey. However, will hold off on issuing any new SCA's at this time until the current SCA has expired. Outlook... Saturday-Tuesday...Conditions are expected to remain below Small Craft Advisory levels through the period. Rip Currents... Winds will increase to 15 to 20 kts today with gusts at SCA criteria. There will be an onshore component for the NJ coast today as winds veer from the south. Given the above, and the 8 second period forecast, the rip risk for Coastal Cape May and Coastal Atlantic will be MODERATE today. The rest of the beaches will be kept at LOW given the orientation of the coastline relative to the wind direction. Winds shift offshore for Friday, so the rip risk for Friday will be LOW. && .PHI WATCHES/WARNINGS/ADVISORIES... PA...None. NJ...None. DE...None. MD...None. MARINE...Small Craft Advisory until midnight EDT tonight for ANZ450>455. && Synopsis...Robertson Near Term...Johnson/Meola Short Term...Meola Long Term...Robertson Aviation...Meola/Robertson Marine...Meola

What this means
Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
