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 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.

11 minutes of warning. NWS OKX issued a tornado warning for this county at 20:57 UTC, 11 minutes before the tornado touched down, in force until 21:15 UTC.

The county was under a severe thunderstorm watch, issued at 17:27 UTC and running to 22:19 UTC.

Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The Storm Prediction Center had this point in a Slight Risk, with a 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 19:48 UTC.

SPC's Day 1 convective outlook as it stood when the tornado began, read at the touchdown point. The same archive is on the radar archive.

The radiosonde launches on either side of the tornado, from the nearest station that was launching then, drawn and analyzed the way Storm Lab does: the same diagram, the same parcel and shear definitions SPC's mesoanalysis uses.

The Brookhaven radar (KOKX), 33 km away, was scanning. The volume nearest the touchdown began at 21:07 UTC.

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.
