Wild Wednesday weather: Inside the tornado warning

RADAR HOOK ECHO

Wednesday afternoon quickly went from sunshine and calm to wild and stormy!

A series of severe storms rolled across the region initially hitting the Finger Lakes with a rash of severe weather. A viewer snapped a picture of a funnel cloud trying but never succeeding to touch down near Mount Morris on Wednesday around 3:30 in the afternoon.

More strong to severe storms developed near and along the Thruway toward the early evening.

One storm showed signs of rotation and in this case it was visible on radar. A "hook echo" often indicates there is rotation as precipitation starts to wrap in association with a mesocyclone.

Advances in radar now allow us to "see" spin inside thunderstorms. The good news is forecasters can get a much better idea as to whether a mesocyclone will produce an actual tornado.

Wednesday's storm over Southern Monroe County showed enough rotation for the weather service to issue a tornado warning. No tornado actually touched down in our region Wednesday - although it's not unusual to have one or two 2 EF0 or EF1 tornados in a particular summer in Western New York.
