A strong and slow moving frontal boundary, along with a potent mid level disturbance triggered strong to severe thunderstorms which impacted Southeastern New York. Six tornadoes also touched down across Long Island with one in Nassau County and five across Suffolk County.

A National Weather Service Storm Survey team in coordination with|Suffolk County Fire and Rescue and Emergency Services confirmed an EF0 |Tornado in North Bellport, NY. A narrow tornado likely touched down in a forest |of pine trees to the south of Sunrise Highway, between Bellport Avenue and Martha Avenue Ballpark leaving a 35 yard northward tracking path of sheared tree limbs and snapped tree trunks towards Sunrise Highway.||Thereafter the tornado likely tracked northeast across Sunrise Highway heading towards The Brookhaven Landfill. In this process it flattened the Sunrise Highway Exit 56 sign, on the westbound side of Sunrise Highway just to the east of the station road off ramp. This approximate location corresponds to a public video showing a condensation funnel and considerable tree debris moving northeast across Sunrise Highway. ||The tornado likely tracked or skipped northeast across the landfill, before causing extensive roof damage and blowing out the north facing garage doors of the Brookhaven Recycling Center. The south side of the recycling center is always wide open, likely allowing for south to southwest winds around the tornadic circulation to|enter the building and cause the extensive roof and garage damage. This Recycling Center is located on the Northeast side of the landfill, which was the end of the visible tornadic path.||Based on radar velocity signatures and damage orientation in relation to the general northeast motion of the parent storm, the damage survey above is determined to be EF0 tornadic damage with winds of 70 to 85 mph.

A National Weather Service Storm Survey Team confirmed an EF1 tornado in Shirely, NY. A tornado likely touched down just southwest of Francine Place and Mastic Blvd, travelling east northeast along the Long Island Railroad tracks and adjacent backyards. |Numerous oak, maple, and pine trees were uprooted and laying in a northerly direction. Several trees were also snapped at the trunk or had large branches sheared off along this path. In addition, minor roof and siding damage was observed for several houses, as well as leaf splatter on south and east sides. The damage swath at this point was only about 25 yards wind. The tornado then hooked northeast over the Lidl Supermarket (Southwestern corner of the Shopping Center Complex), |flipping over a 5 Ton air handler unit on the roof, before tearing off the parapet and collapsing the covered walkway of the Chiptole Mexican Grill on the northeast corner of the Shopping Center. The damage path remained about 25 yards, but damage was consistent with EF1 winds of 95 to 105 mph.||Public video showed the apparent tornadic circulation lifting northeast across the intersection of William Floyd Parkway and Montauk Highway towards the Applebee's Shopping Center, with debris being thrown in one direction then another. Siding and Shingles from the Chiptole were thrown northeast about 250 yards across this |intersection and into The Applebee's Shopping Center. Other than the debris, some small trees were uprooted in the parking lot and laying to the northeast and flashing was ripped off the south side of the Applebee's and unoccupied adjacent retail store. The tornadic circulation may have briefly lifted at this point, with about a 50 yd. swath of 65 to 75 mph straight line winds across this shopping center. ||The tornadic circulation then touched down once again to the northeast of the Applebee's Shopping Center lifting the entire roof off a 2 story multi family residence on the corner of Grand Avenue and McGraw Street. The roof was tossed as far as 150 yards to the north, into the backyard of neighboring houses to the north on Grand Avenue. One section of this roof, actually impaled itself into the side of the neighboring house to the north, and made such a strong impact that it skewed the vertical structure of that house. Based on the extent of structural damage to these houses, and adjacent 50 yd. swath of uprooted, snapped or sheared large trees, this damage was consistent |with EF1 winds of around 100 mph. The tornado strength likely peaked at this point. The entirety of the EF1 Tornadic damage path to the southwest and northeast of Montauk High was around 1/4 mile.||The tornado would then make its way north across Sunrise Highway, skipping its way northeast for the next 4 1/2 miles, with areas of damage consistent with an EF0. On its path it continued northeast through Brookhaven Calabro Airport, flipping over or shift a few small single engine planes, thereafter it moved northeast through Pancho Drive, Titmus Drive, Abbott Avenue, and Burney Blvd just to the east northeast of the airport. Several large trees were uprooted, trunks snapped or branches sheared in an approximately 50 yd. path, with accompanying minor roof, siding and fencing damage in this area. The tornado likely skipped north to the intersection of Barnes Roads and Moriches-Middle Island Road with a small area of additional tree damage, before making a final nearly mile long and 50 yd. wide tornado damage path northeast across Pine Hills Golf Course, and then through the neighborhoods of Foreston Circle, Eagle Lane, Nestledown Avenue, Wading River Road, Tupelo Street and then across to the intersection of Silas Woods Road and South Street before finally lifting. Several dozens of large hard and soft wood trees were uprooted and laying in a Northerly or Northeast |direction, as compared to the east northeast direction of storm movement. In addition, numerous tree tops were completely sheared to stubs and tree trunks snapped. Minor roof and siding damage was observed for numerous houses along this path, with several fences and chimneys destroyed. A large north / south facing camper on Tupelo Drive as rolled westward on its side. The described one mile long, 50 yd. wide convergent tornadic damage pattern was consistent with an EF1 tornado with 85 to 95 |mph winds and was flanked to the southeast by a 500 yd. path of scattered tree and powerline damage and minor structural damage consistent with 65 to 75 mph southwesterly straight line winds.

A National Weather Service Storm Survey Team in coordination with Suffolk County Fire Rescue and Emergency Services confirmed an EF0 Tornado in Remsenburg, NY to Westhampton, NY area. A narrow tornado of 35 yd. width likely touched down at the corner of Ring Neck Road and South Country Road and then continued northeast across Riverview and Crestview Drive, then continuing northeast over Brushy Neck Lane and Jagger Lane Court, up to the bend in Montauk Highway near East Ridge Court.|Several large hardwood trees were uprooted and laying in northeast direction along this path, snapped at the trunk or had large branches sheared, with collateral power line and power pole damage. Several smaller shrubs and young trees were also flattened to the ground. In addition, minor roof and siding damage was observed for several houses along this path. Thereafter the tornado likely skipped along continuing northeast across the cemetery at Station Road to the union of Hazelwood and Rodgers Avenue and South Perimeter Road, with the above describes damage being more intermittent.||The most extensive structural damage occurred at the end of the visible tornadic path at the Department of Public Works Salt Barn on South Perimeter Road on the south side|of Westhampton Gabreski Airport. The north facing reinforced cinder wall of the Salt Barn was blown out. Indications are the roof may have briefly lifted as south to southwest winds with the tornadic circulation blasted into the south facing opening, culminating in the north wall being blown out.||Based on radar velocity signatures and damage orientation in relation to the general northeast motion of the parent storm, the damage survey above is determined to be EF0 tornadic damage with winds of 70 to 85 mph.

A National Weather Service Storm Survey Team in coordination with Suffolk County Fire Rescue and Emergency Services confirmed an EF0 Tornado in the Hampton Bays to North Sea area of Suffolk County. A narrow tornado likely touched down near Tiana Circle, perhaps coming in as a waterspout off of Shinnecock Bay and downing several small pines in a northeasterly direction.||The tornadic circulation likely moved northeast across Smith Creek, with the magnitude of tree damage increasing as it touched down near Mill Race Road. From that point, a 35 yd. wide path of hardwood trees was observed to be either uprooted and laying in a |northeast direction, snapped at the trunk, or having large branches sheared off, continuing northeast through Columbia Street and Washington Avenue, to Hudson Street and Sherman Avenue, and then up to Lynncliff Road and Palo Alto Drive. In addition, minor roof and siding damage was observed for a few houses along this path. This included a homeowner on Hudson Street reporting that a screen door was pulled off the rear of their home and tossed 50 yards northeast of their home as well as a heavy wrought iron table and large gas grill picked up and pinned against their fence.|In addition, a homeowner on Lynncliff Road reported their roof shingles standing on edge as the tornadic circulation came through.||Thereafter, the tornadic circulation likely crossed the Eastern half of Shinnecock Bay, with an intermittent 35 yd. width path of mainly hardwood tree damage skipping along|Peconic Road and Montauk Highway, before likely crossing Shinnecock Hills Golf Course|and a heavily wooded area to the northeast. The tornadic circulation likely dissipated after producing tree damage on Marys Lane, east of North Sea Rd. in North Sea. No visible damage was noted or reported to the northeast of this location, including the Southampton Youth Sports Center.||Based on radar velocity signatures and damage orientation in relation to the general northeast motion of the parent storm, the damage survey above is determined to be EF0 Tornadic damage with winds of 70 to 85 mph.

10 more were confirmed in the United States that day.

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.
