Slow motion recap of lightning from a Severe Thunderstorm approaching Westfield, MA. All clips are recorded from 120fps source, and played back at ¼ speed (30fps), except one, which was recorded at 30fps, and played back at ½ speed (15fps).
Thunderstorm passes by Hudson, NY minutes before being upgraded to Severe. This storm, after passing by here, merged with 2 other cells to form a supercell, and triggered a Tornado Warning in the Westfield, MA area, where a tornado formed in Westfield, MA, and continued on the ground into Springfield, MA. The lightning is kinda messed up, due to my camera. You can see some of the storm in Westfield here.
