Earlier this evening, I witnessed a spectacular lighting show above my house. Flashes of light -- hundreds of them -- all going off in rapid succession across the sky. Only a few of them actually struck the ground. The whole thing lasted nearly an hour, and was accompanied by tornado sirens, thunder, and eventually heavy wind, rain, and in some places, baseball-sized hail. I've never seen anything like it!
This video was taken a few hours ago by someone who lives 20 miles west of me in the city of Menasha, Wisconsin. The storm hit them before it reached us here in Brillion, but it's still the same sky I watched above my house. Awe-inspiring to say the least!
(NOTE: The video does have sound. Just wait for it.)
STORM UPDATE: There was severe damage from strong winds, tornadoes were reported (even one about nine miles north of my house), but, as of this writing, no confirmed injuries or deaths.
VIDEO UPDATE: Here are some more videos of last night's storm:
Above: Video from Grand Chute, Wisconsin (also roughly 20 miles west).
Video from Neenah, Wisconsin.
VIDEO UPDATE: Another fantastic video, also from Winnebago County directly west of my house. This time, the video may have captured one of the developing supercell/funnel clouds.
