A mid-level shortwave trough approached aloft and severe thunderstorms were produced in the warm sector over southeastern NY along a pre-frontal trough ahead of a cold frontal passage. These storms produced damaging wind gusts and a tornado.

Tornado in SUFFOLK, NEW YORK
From 25-SEP-22 22:17:00 to 25-SEP-22 22:20:00 (EST-5)
Location: LAUREL
Tornado F-scale: EF0
Property damage: 100.00K
Crop damage: 0.00K
Reported by: NWS Storm Survey

A National Weather Service storm survey team, in
coordination with Suffolk County Fire Rescue and Emergency
Services has confirmed an EF0 tornado in the Mattituck area of
Suffolk County NY.
Based on analysis of the storm survey findings and OKX dual pol
radar reflectivity, velocity and derived data (including a
tornadic debris signature), it was determined that an EF0 tornado
first touched down at Juniper Hill farms around 1117 pm, damaging
a greenhouse and downing a couple of large trees on the property.
The tornadic circulation likely lifted or skipped along as it
tracked east northeast across a one mile stretch of remote wooded
area, before touching down and shearing several tree tops and
large limbs in the vicinity of Cottage Way, Walnut Place, and
Lipco Road, between Sound Avenue and Old Sound Avenue. Peripheral
straight line wind damage to a large tree was noted near Shirley
Road and Horton Avenue to the north of Sound Avenue as well.
The tornadic circulation likely skipped east northeast in the
vicinity of Old Sound Avenue/Main Street over Love Lane and
Wickham Avenue with spotty tree damage noted, before definitively
touching down once again between Wickham Ave and Mary's Road to
the north of Pike Street, with a large maple tree sheared a few
feet from its base, minor siding and roof damage, and leaf
splatter on the west and south sides of homes. This most
prominent damage path, about 50 to 75 yards in width, continued
across Mary's Road, where 3 evergreen trees were snapped at their
base in a convergent pattern (the 2 southernmost trees laying in a
northeast direction and the northernmost tree laying in a
southeast direction). The tornado continued eastward across the
Mattituck-Cutchogue Jr/Sr high school track, twisting and damaging
a large scoreboard, overturning metals benches, and laying down a
100 ft section of wind fence on the north side of the adjacent
tennis courts in a northerly direction (again consistent with a
convergent wind pattern). The tornado then continued east over the
high school, ripping up large sections of asphalt roofing
material over one of the main buildings. The damage across the
high school grounds was the most severe along the path, consistent
with tornadic winds of 75 to 85 mph.
The tornado then exited east over an area of homes on Village
Lane, causing significant tree and fence damage to several homes,
before likely lifting around 1120 pm as the rotating storm
continued eastward over the farm fields and vineyards that lay to
the east. No visible damage was noted to the east of this point,
marking the presumed end of the tornado path.
