26 May 2012 LaCrosse, KS Tornado
Chaser Scott Currens put together this slideshow (creating a sort of choppy, but interesting, time lapse) of the 47-minute lifecycle of a tornado northwest of LaCrosse, KS. The tornado developed at 9:16 pm and dissipated at 10:03 pm.
Marla Bickler has a much closer view of the lengthy tornadogenesis mode ... I suggest a "mute" unless you like 80s movies.
