Meteorological synopsis
On July 12, a supercell thunderstorm developed over eastern New Jersey in association with a surface low-pressure area in southwestern Ontario. Daytime heating in the Tri-State Region led to moderate instability, a key factor in the development of showers and thunderstorms. With conditions favorable for the development of a tornado, the Storm Prediction Center issued a tornado watch was issued at 12:40 p.m. EDT (16:40 UTC). At around 1:05 p.m. EDT (17:05 UTC), a thunderstorm produced winds up to 60 mph (95 km/h) in Warren County, which snapped tree limbs and damaged power lines. A stronger thunderstorm developed around 2 p.m. EDT (18:00 UTC) and produced a funnel cloud near Carlstadt at around 2:45 p.m. EDT (18:45 UTC), no damage was associated with the funnel. That same storm became stronger and developed into a supercell thunderstorm as it crossed into New York. At around 3:30 p.m. EDT (19:30 UTC), an F1 tornado touched down near Grand View-on-Hudson along the Hudson River in Rockland County. The 100 yard (91 m) wide tornado touched down on a dock before becoming a waterspout as it crossed the river. The tornado passed near the Tappen Zee Bridge before crossing into Westchester County. The tornado hit the town of Sleepy Hollow, New York around 3:37 p.m. EDT (19:37 UTC), two minutes later, a 58 mph (93 km/h) wind gust was reported along the periphery of the tornado. As the tornado neared New York State Route 9A, it intensified into an F2 system, packing winds up to 157 mph (253 km/h), and struck the California Closet Warehouse. At this time, the tornado was estimated to be 300 yd (274 m) wide. Shortly after, the tornado weakened back to F1 intensity. Minor damage was reported through the Kensico Reservoir in Valhalla as the tornado neared the New York/Connecticut border.
