A weak cold front moved southeast across Iowa during the afternoon of the 26th.  The airmass was quite capped and thunderstorm development was limited.  CAPE values by mid to late afternoon reached 3000 to 3500 J/kg just ahead of the front.  Surface temperatures topped out around 90, with dew point readings in the low to mid 70s.  Thunderstorms erupted just ahead of the front, but the line of storms was scattered to broken at best.  For the most part, the storms produced hail around an inch in diameter.  There were two reports of golf ball size hail from one cell as it moved through the Mitchellville area of Polk County.  There were reports of high wind from a few of the cells in southwest Iowa.  Trees were blown down by 60 MPH winds west of Lenox.  The scattered line of thunderstorms produced winds of 60 to 70 MPH.  The greatest damage reported came from Union County in the city of Kent.  High winds damaged part of the front of a brick building and tore off a large barn door.  Most of the other wind damage was limited to downed trees and power lines.  One tornado touched down briefly in Tama County.  The tornado reportedly only touched the ground and caused no damage.
