Ok, now with the chase, ugh what a deal! We took off at 3:00 with an initial target of Onawa, IA. We got to Onawa around 4:30 just as the SPC issued a tornado watch further south, so we pressed onto Missourri Valley, IA. We sat there, grabbed supper and then checked data, we noticed there was a cell SW of Sioux City, IA that we could easily get to with strong rotation. We didn't really want to risk going back north too bad as we knew if we went up north and this storm dies that would be the last of chasing for the night because it would be too late to get to the southern IA storms that were rolling in. We then got a call from a nowcasting EXWX team member saying... go go go, so we listened and took off North!
The whole drive up to this storm I was really nervous knowing that this could be a complete bust and die on us when it hits the Missourri River but if it survived past the river it would really take off and go crazy, it was a risk that we took. We got back up to Sloan, IA and watched the storm die off :( It's part of chasing, you bust sometimes so we weren't upset, just bummed. We met up with Marc Hicks and Brent Koops in Sioux City and shot the shit for a little bit before heading home. Here are the pictures right before the storm died.
