Three tornadoes touched down in western New York this afternoon associated with a beast of a supercell that moved onshore from Lake Erie. The storm produced an EF-2 tornado that was on the ground for 5 miles in the town of Hamburg and a second EF-1 tornado on the ground for 2.5 miles in the town of Holland.
Today, the National Weather Service confirmed a third EF-1 tornado in Allegany County that was on the ground for an additional 4.2 miles.
For most of the storm's life radar detected a large amount of lofted debris as the tornado sucked all sorts of debris up in to the clouds.
This Tornado Debris Signature (TDS) was apparent for about 25 minutes as the storm traversed Erie County, NY. Unfortunately, the radar confirmation of the tornado was not relayed by the National Weather Service in warnings, statements or even in the NWS Chatroom available to the media and emergency managers.
The complex of thunderstorms responsible of the tornado and a smattering of other damage reports in New York and Pennsylvania moved south of Connecticut tonight. Behind it, quieter weather is moving in with plenty of sunshine and warm weather for Friday. High temperatures between 90 and 94 degrees will be common across the state.
