I feel like the main show is fine (besides the fact that it could use some new elements). I think the preshows should focus more on how weather effects are created for movies. It should be presented by Spielberg.
Would be cool to have Universal Partner up with the weather channel to feature a new ride or some new elements or whatever. IF that means re-branding, re-theming but keeping the severe weather concept, would be cool as well. Florida having most hurricanes, lightning strikes, tornados per sq. mile would help support this feature idea !
