What the reports say
Written by National Weather Service staff at the time of the event · public domain
Several dozen trees and power lines were reported down in Great Neck, with several trees uprooted. A NWS Storm Survey found an area of damage that extended over a broad area extending from Old Pond Road east to Hampshire Road, with downed trees facing south and east in those areas respectively in a fanned-out fashion indicative of a microburst. The most severe damage in this swath was concentrated along Old Pond and Strathmore Roads, with dozens of healthy hardwood and pine trees uprooted or snapped in two. This damage is indicative of maximum winds of 100 mph. The path length and maximum path width of the microburst were 0.75 miles. Some of the trees fell onto houses and cars.
A hot, moist and unstable airmass lead to another round of thunderstorms and a variety of severe weather during the afternoon. The storms were quite numerous over interior sections of southeastern New York, becoming more isolated as they neared the coast. Strong winds downed numerous trees and power lines and lightning strikes generated several fires that caused substantial damage. Torrential rains lead to significant street and highway flooding in some locations. Funnel clouds were also reported in a couple of locations and fortunately remained aloft.
