What the National Weather Service wrote
A tornado briefly touched down in a few locations. The first report of a touchdown was in Woodmere where several trees and powerlines were down. From there, the tornado lifted and skipped in a few locations as it traveled nearly 50 mph to the northeast towards Hempstead, Uniondale, and Levittown. Here, damage reports were sporadic, but in Uniondale NY, the tornado touched down again and tore a roof off a two-story colonial building on Liberty Street, which landed on a nearby house. Scattered debris, including shingles, insulation and twisted siding was thrown into the next block up, including the intersection of Emerson and Goodrich Street. Significant damage was also noted near Clover Lane in Levittown, where a large tree was felled onto a house before the tornado lifted.
