Mike Brady of ChaserCentral Chased the Iowa 5% tornado On October 23rd 2010. 610 Miles and 11.5 hours of round trip driving failed to yield anything of significance. Mike got on the storm cell near Osceola Iowa the storm showed a good updraft with strong upward motion. The cell appeared to be blocked by a upper level cap. There was a decent lowering on the storm and all and all it wasn’t a bad chase for Iowa.
