Here is a video I took (quality isn't good) of what looks like a funnel cloud the date I didn't recored but I'm guessing it was about 5 years ago in the summer and there was no tornado warnings for Genesee county just thunder storm warnings.
Here is another video from about 7 or 8 years ago looking out my back yard in Batavia in the summer at night just before a thunder storm. There was no thunder so I took out the audio and I also used the camcorders night vision to enhance the look
I love to catch lighting on tape so if I get any more I'll post them for the weather buff here in Batavia on the www.thebatavian.com
