Roger lives just east of Denver Colorado in the heart of the high plains where tornadoes and supercells rule. He has been chasing storms of all kinds for over 20 years. He has seen and videotaped over 375 tornadoes in his chasing career, and nearly a dozen hurricanes and typhoons. He chases anytime a severe weather threat exists either on his storm chasing tours or after the regular season is over often with his wife Caryn. He has also been a probe driver for various National Severe Storms Laboratory projects and has taught Skywarn training at several locations across the plains.

He has been contracted by The Weather Channel for the past 11 years to shoot and edit video of everything from tornadoes to floods to blizzards and hailstorms. He has also done much work for The Discovery Channel, The Learning Channel, National Geographic, The Travel Channel, NOVA, BBC and many more. Roger is co-owner of Silver Lining Storm Chase Tours.

Tim Samaras has been a rather passionate chaser for 20+ years. The famous Colorado Convention series actually started in his home with a few friends who share the same passion of storm chasing and to fend off the winter blues. Pizza was ordered, and the evening was spent watching videos and talking about those terrific spring days and the forecasts that brought those chasers there. Discussions took place to make sense out of the upcoming spring and what bounty it would bring. Comradre, chase strategies, and perhaps some chase stories being stretched a little due to a rather strong inflow were commonplace. With friends like Roger Hill and Brad Carter whom also share the same passion, the ball just kept rolling!

Tim can be seen out each spring with some sort of new gadget, idea, or contraption. Last year it was the development of some special probes that were developed by him and the company he works for, Applied Research Associates, Inc., where he was awarded an SBIR PHASE II from the Department of Commerce/NOAA to develop the next generation of TOTO(TOtable Tornado Observatory), and the NSSL Turtles, to measure the meteorological parameters of the violent regions of a tornado core. On May 7th, 2003 he and Brad Carter were successful in the deployment of these probes within the large F-3 tornado in SW Kansas on May 7th, 2002. Last year they were successful in getting one of these probes directly in the path of a tornado

He has also escorted the BBC, National Geographic, Pioneer Productions, local news media/paper folks out to tornado alley where they all were able to witness the most violent storms on earth: The Tornado.

David has been chasing storms for over 20 years on the Southern Plains, primarily in the Texas Panhandle, North Texas, Western Oklahoma, and Western Kansas, but has been known to chase as far away from home as Iowa.
