New York State Thruway Tornado

A strong line of thunderstorms across upstate New York spawned a tornado yesterday near Amsterdam. A supercell developed in a bookend vortex on the northern portion of a squall line that was moving along the New York State Thruway west of Albany. Doppler radar showed the low level mesocyclone extremely well with one of the more impressive couplets you’ll see in the northeast. It only lasted a couple volume scans before the circulation weakened but it was long enough to produce a tornado.

The tornado was captured on video by a recent SUNY-Albany graduate with a degree in meteorology! She was pulled over at a rest area on the Thruway when the she spotted the tornado crossing I-90. Fast forward the video to about 5:30 to see the tornado.
