Watching a mesocyclone form is a grand spectacle. While railfanning Colbert, GA, this happened right above this town. Besides trains, enjoy spectacular footage of the thunderstorm cell genesis - the formation of the collar cloud surrounding the cloud base, air surging up into the updraft, forming the wall cloud... The ominous greenish sky adds color to this amazing storm mechanics. Cyclonic (anticlockwise) rotation is visible and also indicated on Doppler radar. Hail core and strong winds are reasons for the NWS office to issue a Severe Thunderstorm Warning for the area. The storm doesn't get sufficiently organized to form a funnel cloud or a tornado, but turbulences at the wall cloud's base are indicative of the violent processes inside the cell. The trains appearing in the video are also quite interesting. We watch moves of A752, the Athens local, with a GP39-2 and GP38-2 in Colbert before the storm unfolds. A Loram shoulder ballast cleaner with the CSX symbol W052 passes the town while the wall cloud hangs right over it. Later, manifest Q582 goes south and meets the remarkable military train with construction vehicle loads. It has two Union Pacific engines for power at the head end and a DPU on the rear, sandwiching 94 flat cars. Happy watching!
