Season 1 (2007)

During the 2007 season, which consisted of 4 episodes, Josh Wurman and Sean Casey's team used a fleet of three vehicles: the Tornado Intercept Vehicle (or TIV), the Scout (a modified 1993 Nissan Pathfinder), and a Doppler on Wheels (or DOW). Team members for the 2007 season included Herb Stein (DOW driver), Mara McFalls (scout driver/journalist), Justin Walker (scout navigator/meteorologist), Danny Cheresnick (DOW navigator/meteorologist), and Karen Kosiba (DOW navigator/meteorologist).

11 "Opening Pursuits" October 17, 2007 (2007-10-17)
In the beginning of the show, the science team, led by Joshua Wurman, and the TIV team, led by IMAX filmmaker Sean Casey, are displayed and new technologies are explained. Sean explains how he has tried to gain an IMAX shot from inside a tornado for the past eight years. As the chase season starts, the TIV attempts to intercept a supercell near Hereford, Texas, before hearing that an EF2 rated tornado has hit Tulia, Texas. The TIV then tries to intercept a tornado at night (without filming) and succeeds near Stafford, Kansas
22 "A Dangerous Ride" October 24, 2007 (2007-10-24)
The Storm Chasing team is chasing again after a slow period in the eight-week tornado season. The team is chasing in the Texas Panhandle where a monster supercell threatens the TIV team as they try to intercept the cell. The team misses and chases into Kansas, where a supercell explodes producing multiple tornadoes near Protection, Kansas. Once again, howevre, the team fails to intercept the storm. 
33 "Tornado Aftermath" October 31, 2007 (2007-10-31)
As the teams try to chase a supercell near La Crosse, Kansas, they hear that an EF5 tornado has struck the town of Greensburg, Kansas (the first tornado in eight years to be given this rating). Before this happened the team chased a cluster of storms in South Dakota. At the same time, Howie Bluestine manages to intercept a cell near Woodward, Oklahoma. Sean and Josh hear about the Greensburg tornado while in Hays, Kansas after a long and costly chase day. 
44 "Direct Hit" November 7, 2007 (2007-11-07)
In the final weeks of the season, Sean is desperate to get the shot he is trying to achieve. A tornado forms earlier than expected and nearly touches down near Woodward, Oklahoma. In the middle of the episode, the TIV breaks down and the team loses two valuable days chasing. On the last day of the season, all the teams are on the verge of defeat when a cell erupts near Nickerson, Kansas. The TIV manages a valuable intercept and gives Joshua Wurman vital data. 

Season 2 (2008)

For the 2008 season, which consisted of eight episodes, Wurman and Casey's team and its vehicles were expanded and upgraded as follows: 1) the DOW 3 was replaced by the new DOW6 (based around an International 7500 truck) with improved speed, power and range; 2) the original TIV was augmented by the new TIV2 (both versions are still used in the field); and 3) two new vehicles, PROBE 1 and PROBE 2 (modified Dodge Ram 1500s), were used to deploy probes. Justin Walker (navigator-meteorologist), and his wife Hannah (driver) rode in PROBE 1, while Danny Cheresnick (navigator) and Aaron Rupert (driver) manned the original Scout vehicle. Beginning this season, the series also followed Reed Timmer and the crew from the website (TVN). The TVN vehicle is a 2008 Chevrolet Tahoe[1]

Due to popular demand, the Storm Chasers series was aired in the UK starting on February 17, 2009. The Science of Storm Chasing series never came to the UK.

Season 3 (2009)

On May 18, 2009, Discovery Channel renewed Storm Chasers for a third season which began airing in the Fall of 2009. Reed Timmer and the TVN team return with their new "SRV Dominator" vehicle. Dr. Josh Wurman and his DOW team have now joined the massive, government-funded VORTEX2 research project, leaving them with little time to aid filmmaker Sean Casey. Casey and his TIV team return in their improved TIV2, and are now assisted by a new team of meteorologists in TIV Doghouse (a Dodge Ram 2500 equipped with weather radar, GPS and HD filming equipment). A new team known as TWISTEX led by veteran storm chaser Tim Samaras along with Carl Young and Tony Laubach join the series driving TWISTEX Probe (a modified 2003 GMC Sierra Denali) and Twistex M1-M3 (three modified Chevy Cobalts). Also returning are Danny Cheresnick and Aaron Ruppert in their SCOUT vehicle (a new 2009 Jeep Wrangler replaces the old Nissan Pathfinder).[1][2]

Timmer's new SRV Dominator is heavily modified version of the Chevy Tahoe used in the previous season. The vehicle now features thin armor shell composed of sheet metal and lexan, giving it an appearance similar to Sean Casey's TIV1. While the new armor allows Timmer and his team to get much closer to a tornado than a conventional vehicle, it cannot actually drive into one like the heavier TIV vehicles.[1] Other additions to Timmer's team include a new advanced radar and an experimental remote controlled aircraft with a 12-foot wingspan, designed to fly around tornadoes with an advanced auto-pilot system, and drop small probes into tornadoes.[3]

The first episode starts with the TVN crew explaining their new vehicle the "SRV Dominator" which is a heavy modified Chevy Tahoe, made like the TIV, but not heavy or strong enough to actually drive into a tornado. While TVN was on their first chase they were able to get close to and record an EF-1 tornado in Oklahoma. Meanwhile, Sean explained his new chase crew does not feature anybody from last season other than the TIV crew. While on their first chase, Sean's team gets lost and misses the first tornado of the season.

The Vortex 2 team (Josh Wurman and the DOW, the Walkers, and the others) did not appear until the 3rd episode, and do not appear again until the 7th episode.The scout team only appeared in the 4th episode.

113 "Storm Catchers" October 18, 2009 (2009-10-18)
The season begins with the TIV team and their Doghouse support vehicle, the TVN team in their SRV Dominator, and the Twistex Team. Reed and the TVN team have early success, nearly driving their new vehicle directly into an EF-1 tornado in Oklahoma. The TIV team, still chasing in TIV1, while waiting for the repairs/modifications on TIV2 to be completed, has a bad first day when communications and navigation problems cause them to miss a potential intercept. 
214 "Bigger In Texas" October 25, 2009 (2009-10-25)
Sean and Reed have a tense and awkward meeting at the New Mexico border. Sean, who was already annoyed at Reed's early success and general attitude, was further annoyed by Reed's new vehicle, the SRV Dominator, which he felt was a blatant attempt to copy his TIV idea. The Twistex team has a successful day, coming within a few hundred feet of an EF2 tornado. The TVN team enjoys slightly less success without their usual driver, Joel Taylor. The TIV team has another bad day, as communication problems once again cause them to miss a valuable intercept, and taking a muddy road causes both TIV1 and Doghouse to get stuck. 
315 "Highway to Hail" November 1, 2009 (2009-11-01)
Reed steps up his science to take on Dr. Josh Wurman's massive research project. However, when his decision to mount a small radar on his vehicle threatens to interfere with Dr. Wurman's project, tensions between the two rise. TVN's driver Joel Taylor has second thoughts about chasing with the team, when his and Reed's relationship becomes strained. With his much improved TIV2 finally out of the shop, Sean is feeling confident and happy to rejoin his old chasing partner, Dr. Wurman and his new VORTEX2 project. However, when Dr. Wurman seem less than thrilled to see Sean, and makes it clear that getting TIV2 inside a tornado is no longer high on his list of priorities, Sean is somewhat offended, and decides to resume chasing alone with Doghouse, at least temporarily. 
416 "Inside the Tornado" November 8, 2009 (2009-11-08)
TIV2 suffers another mechanical failure, leaving Sean Casey on the sidelines. Joel Taylor decides not to chase with Reed and instead joins the SCOUT team of Danny Cheresnick and Aaron Ruppert on a chase in Oklahoma. However, on the same day, Reed and the TVN team become the first to record ground-level radar data from inside a tornado when their SRV Dominator is engulfed by a vortex near Kirksville, Missouri. Nearby, the TWISTEX team has close encounters with the same storm system.Also joining the TVN team is a guy named Hank Reinhardt. 
517 "Not in Kansas Anymore" November 15, 2009 (2009-11-15)
Reed, Tim, and Sean encounter the strongest tornado conditions of the season. Two strong risk areas have developed over Colorado and in Northeast Kansas. All three teams decide to pursue the eastern event as it crosses from Kansas into Missouri. Each team's efforts to keep up with a developing supercell are hampered by road-clogging scores of amateur chase vehicles all trying to get a glimpse of the same storm but the storm did not form a tornado. Adding insult to injury, Tony is stunned to learn that a strong tornado has struck his and Tim's hometown of Denver, Colorado (a result of the western storm system they had chosen to ignore that day). Frustrated and exhausted, TWISTEX decides to chase a low-risk event in Western Kansas the following day, and manages a successful intercept. 
618 "Fight or Flight" November 22, 2009 (2009-11-22)
Reed and Sean chase in central Kansas, and successfully encounter a developing supercell. Sean is in perfect position to intercept, but both he and the Doghouse have difficulty finding the tornado as it becomes cloaked in precipitation. Reed relishes the opportunity to launch his $30,000 remote-control airplane, which successfully deploys three parachute probes into the tornado inflow, gathering vital data. However, Reed quickly finds himself in a vulnerable position when the tornado begins to take an erratic path and doubles back on itself (and the Dominator). 
719 "Sean Casey at the Bat" November 29, 2009 (2009-11-29)
Sean returns chasing with his old chase partner, Dr. Josh Wurman and his new giant project, VORTEX2 and DOW7. In Wyoming, TIV2 intercepts an EF3 tornado, and Sean gets the shot of the tornado coming directly in his direction and impacting the TIV, the shot he chased by ten years. Meanwhile, Reed follows the same storm. He drives into hail storms and the Dominator temporarily gets stuck in the mud. 
820 "EF-3 Strikes You're Out" November 29, 2009 (2009-11-29)
As the season comes to a close, Reed is left bloodied when a violent tornado shatters one of the Dominator's windows. Meanwhile, Tim's team has their own close encounter as they deploy probes in the last chase of the year. Having ended their chasing season in the previous episode, Sean Casey and his team are absent from this episode. 

Greatest storms 2009 is also an episode of 2009.It is a special about the show. Bonus material is also an episode. This season is on DVD.

This season continues to feature the three groups from the previous season: The TVN team is led by Reed Timmer and rejoined by driver Joel Taylor, who had temporarily left the team the previous year. IMAX filmmaker Sean Casey returns seeking better tornado footage, this time employing a second-unit IMAX crew to film TIV2 itself. The TWISTEX team led by veteran storm chaser Tim Samaras also returns with a new "TWISTEX Probe" vehicle (a 2008 GMC Sierra HD with extensive weather instrumentation).[1] One of the major events early in the season is the TVN crew's encounter with the aftermath of the April 2010 tornado outbreak in Yazoo City, Mississippi. This was the last season to feature TIV2 Navigator Matt Hughes who died May 26, 2010. Matt's last chase is in the show "Dedication" which is dedicated to Matt Hughes.

Now there's a powerful storm tracking toward downtown St. Louis, and after a hot start to the season, Reed Timmer has suddenly lost his mojo. A series of bad decisions leaves team Dominator out of position and at each other's throats. After completing an IMAX film that was ten years in the making, Sean Casey is using his armored TIV to film a sequel in 3D. But first he needs to find the right storm. Team TIV has a 3-D turret. Tim Samaras and team TWISTEX follow the path of destruction into the St. Louis area, and in an attempt to place their probe in the path of a tornado they end up chasing too close. The hunters become the hunted and the team ends up running from the beast. The next chase is in Texas, where a multiple-vortex tornado is intercepted. 
331 "Reed's Redemption" October 9, 2011 (2011-10-09)
After failing to find a twister on two consecutive chases, Reed Timmer and the Dominator team are desperate to chase one down. They're even desperate enough to pursue a powerful storm into an urban area after dark, one of the most dangerous possible chasing scenarios. Team TWISTEX's truck threatens to keep them on the sidelines on a promising tornado day. While team Dominator pursues an intercept, the TIV team is hoping to finally shoot their first ever 3D tornado footage... but tension in the vehicle has everyone on edge, and the crew is finding out that the only thing worse than having a chase ruined by the slick, Texas mud is to be helpless in the path of a tornado. This storm system is along the Texas/Arkansas border. 
432 "Aftermath" October 16, 2011 (2011-10-16)
In the wake of the deadly and very large tornado outbreak (April 27, 2011), all three chase teams take time to help with the recovery effort.
