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 TornadoVideos.net (TVN). The TVN vehicle is a 2008 Chevrolet Tahoe.
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.
