September 16, 2006 - Canistota, SD It was exactly 3 years ago today that Michael and I were chasing a two day setup in Kansas and then South Dakota. The first day in Kansas we saw some good supercells with rotation but no tornadoes. We overnighted near Blair, NE for the main show on 9/16. It was the remnants of typhoon Ioke that has wondered around in the pacific and then up by Alaska and on this day was coming into the plains as a trough.
We met up with Chris Collura in Sioux City, IA and hung out for a bit looking at data at a hotel along the interstate when we decided to shoot a bit north towards Sioux Falls, SD. On the way up a lone supercell to our west along I-90 formed and before it was barely a blip on the wxworx system the county went severe warned!
We shot west out of Sioux Falls on I-90 and rapidly approached the developing cell and pulled off at the Canistota exit just in time to see a cone begin to drop from the spinning wall cloud. For what seemed like a good 10 minutes we watched the tornado pass over groves of cottonwood trees and then as it passed there was an empty field there. The tornado was completely pulverizing them into match sticks!
We shot back east on I-90 and watched as the tornado came up to the overpass and then seemed to come down the highway towards us as the stout cylinder above! This was the first and only time I have heard the 'tornado roar'. It sounded like a waterfall with just a hint of a whining sound.
It passed into the field in front of us and roped out into a long snakey tornado and then it was gone..

Things are shaping up for a potentially big fall severe outbreak on thursday Oct 1! The GFS is showing a negative tilt trough punching into the plains into 2000 J capes. Right now the plan is to head out weds night to Russell and be in place for this event. We've been waiting for a month now for a fall severe episode and this time it looks like it will come together!

April 26, 2009 Roll, OK - tornado #2 of the day from the single supercell that formed in Roger Mills county Oklahoma. This tornado crossed the road in front of Eric and I with an intense RFD blast on the south side of it. It tracked down into a valley where it destroyed an unoccupied mobile home. Literally turned it into white dust before our eyes. The tornado continued to climb the far side of the valley (photo above) and dissipate. No other tornadoes formed from the storm that day.
