VORTEX2 Intercepts Its First Tornado (Posted By David Stark)

On Friday June 5, 2009, The VORTEX2 team intercepted a tornadic supercell near La Grange, Wyoming. The MGUAS teams launched balloons around the storm to observe its inflow environment, forward flank baroclinicity, and rear flank environment. Thankfully, the tornado did not harm anything other than a few trees and several fences. That does make trying to figure out how strong the tornado was more difficult. The National Weather Service did a damage SURVEY and rated it an EF-1 pending data from V2. The Doppler on Wheels data needs to be analzyed further, but it is possible the wind speeds were stronger than what the NWS saw from the little damage the tornado caused. Below are two photos that I took during the intercept. My sounding truck was located approximately 10-15 miles from the tornado.
