Here is where I first saw it. It’s a
recollection from Bill Murray (not THAT Bill Murray lol) on the 4/3/74 outbreak. He co-hosts weather brains with James Spann. This seems to be the storm itself and the tornado.
Just before 10 p.m., the announcers at WFMH were broadcasting from their transmitter, observing the storm to their northwest. They read a bulletin from the Weather Service that stated that the storm over Marion County was moving at over 120 mph! I had always heard that the faster the storm was moving, the more severe it must be. Moving at double anything I had ever heard of.
