A passing pre-frontal trough and cold front, coupled with a mid level disturbance, produced severe thunderstorms across Southeast New York. The largest impact was across the Lower Hudson Valley, where there was at least one supercell, which produced a tornado in Orange County, and caused a microburst in Westchester County.

A COLD FRONT WILL TRACK THROUGH THE REGION TONIGHT. HIGH PRESSURE
BUILDS IN FROM THE WEST SATURDAY. HIGH PRESSURE OVER THE AREA SUNDAY

STATE. MEANWHILE...850MB JET STREAK ALSO STRENGTHENS OVER THE
REGION WITH WINDS INCREASING TO 45-50KT ALOFT THIS EVENING.
SURFACE INSTABILITY HAS BEEN LIMITED BY CLOUD COVER...BUT IS
SUFFICIENT OVER WESTERN PORTIONS OF THE FORECAST AREA TO SUPPORT
THUNDERSTORMS. THE COMBINATION OF INSTABILITY AND FAVORABLE UPPER
DYNAMICS HEIGHTENS THE RISK THAT THE STORMS APPROACHING FROM THE
WEST WILL SUSTAIN THEMSELVES AS THEY MOVE INTO THE NEW YORK CITY
METRO AREA AND THE LOWER HUDSON VALLEY. SOME STORMS MAY BE
SEVERE...WITH DAMAGING WIND GUSTS BEING THE PRIMARY THREAT. SEVERE
THREAT BECOMES LESSENS OVER CT AND LI WHERE CLOUDS HAVE BEEN IN
PLACE ALL DAY.

THE DEEP MIXING INDUCED BY THE NW FLOW WILL ALLOW FOR ABOVE NORMAL
TEMPS...MOSTLY IN THE UPPER 80S TO LOW 90S. DEW POINTS WILL DROP
INTO THE LOW 60S BY AFTERNOON...RESULTING IN HEAT INDICES VERY
CLOSE TO ACTUAL TEMPS.
HIGH PRESSURE CONTINUES OVER THE REGION SATURDAY NIGHT WITH CLEAR
SKIES AND LIGHT NORTHERLY WINDS. RADIATIONAL COOLING WILL ALLOW
TEMPS TO DROP INTO THE LOW 50S OVER INTERIOR PORTIONS OF THE
REGION AND PERHAPS THE PINE BARRENS. LOWS IN THE LOW 70S EXPECTED
OVER METRO NYC.
&&
.LONG TERM /SUNDAY THROUGH FRIDAY/...
SUNDAY THROUGH MONDAY MODELS IN GOOD AGREEMENT WITH THE HIGH MOVING
SOUTH OF THE AREA...AND WITH A COLD FRONT APPROACHING MONDAY. THE
NAM BEGINS TO LAG WITH THE FRONT FOR MONDAY NIGHT. USED A BLEND OF

JMThe Albany radar (KENX), 125 km away, was scanning. The volume nearest the first event began at 20:54 UTC.
8 thunderstorm wind, 2 hail, 1 tornado, 1 funnel cloud. Local standard time, as filed.
A large tree was reported down at the intersection of Johns Road and Howard Drive near Scotchtown.
Based on a storm survey performed by the National Weather Service, radar signatures, and eyewitness reports, the National Weather Service confirmed an EF-1 tornado that ran from Goshen to Blooming Grove NY, on Friday July 29th.|The tornado touched down near 109 Coleman Road and lifted near 600 Craigsville Road in Goshen, then skipped along near Craigsville Road, before finally lifting near 379 Prospect Road in Blooming Grove. All along this path, trees converged into a well-defined narrow path. The most significant property damage occurred on Hasbrouck Road in Goshen, where 2 houses directly across the street from one another - 101 and 110 Hasbrouck - were impacted. At 101 Hasbrouck Road, roof shingles were torn off, skylight windows were blown in with glass shattering, and debris was embedded all along the sides of the house including a small branch that went right through a gutter. At 110 Hasbrouck Road, trees were draped all over the house with minor structural damage.
Multiple large trees were reported down near Vails Gate.
Half dollar size hail was reported in Blooming Grove.
Quarter size hail was reported in Blooming Grove.
A funnel cloud was reported near the intersection of Railroad Avenue and Route 9W near West Haverstraw.
Multiple trees were reported down around Croton-on-Hudson, including on 4 homes and several cars.
A storm survey team consisting of meteorologists from the National Weather Service and staff from the Westchester Office of Emergency Management conducted a ground and aerial survey of wind damage from thunderstorms on Friday July 29th. Based on information gathered during the survey and conversations with local residences, the damage is being attributed to a microburst. The microburst had estimated maximum gusts of 80 mph associated with it, a path length of about 1.4 miles, and a maximum path width of 0.4 miles.
Damage from this microburst began on the Croton River along Route 9 and spread south-southeast towards central Ossining. The damage consisted primarily of snapped trees. A large 3-4 foot diameter tree fell on Route 9 near Eagle Bay Drive taking down power lines that resulted in the snapping of several telephone poles. Significant tree damage occurred at Cedar Lane Terrace at 6 Meadowbrook Drive. The tree damage was noted in a divergent pattern.
Multiple trees were reported down along the Saw Mill River Parkway from near Exit 29 to near Exit 32.
Numerous trees and wires were reported down throughout Elmsford.
A tree was reported down on Ogden Avenue in White Plains.
Large tree branches were reported down, taking down power lines along East 102nd Street in the Canarsie section of Brooklyn.
