The air date for the first episode of Season 3 of Storm Chasers has been pushed back a week to Sunday, October 18 at 10:00 pm Eastern on Discovery..  Here is a promo clip for Episode 1, which I believe features the April 26 chase in Northwest Oklahoma, where two tornadoes were produced just minutes apart near the town of Roll.  Tim Samaras and the Twistex team are also introduced as the newest group on Storm Chasers, as they deploy probes and measure the environment in and around tornadoes.
