June 6th, 2006 Eastern Iowa Supercells

June 6 was a day that had decent supercell potential, but we underestimated the tornado potential farther north. Several tornadoes touched down in Wisconsin, which was too far for us to get to. We played the outflow boundary/front intersection over eastern Iowa. By mid afternoon, a supercell developed near Iowa City that became tornado warned for 2 hours, followed by 2 more supercells farther south in Washington county and finally Ottumwa that were beautifully structured. The corkscrew supercell above was near Ottumwa and was tornado warned, and rightfully so! In the end, the low level flow was just too weak to produce an significant tornadic activity.
Vault region of the Iowa City tornado warned supercell. Look close and you will see a funnel halfway down!
Hail to golfball size fell from the Iowa City supercell. The Washington county supercell with flared base.
The Washington county supercell, now HP. Western end of the supercell with nice structure.
Caryn and I couldn't resist a photo in front of this beast!
