Same rumbly Tstorm..this time with my other Sprandom camcorder(s)...facing SOUTH..and I really got some real very hard rumblers from the newly developing big Tstorm cell to my S, SE and ESE....also notice the loud lightning-static heard off the AM-radio.......as the Tstorms were racing to the NE at 40 mph..hence the rapid clearing also shown.....
