A very unstable airmass was in place over Iowa during the afternoon of the 23rd.  Surface temperatures soared to the low to mid 90s in most areas, with dew point temperatures in the upper 70s to mid 80s.  This resulted in most unstable CAPE values of 5000-8000 J/kg and lifted indices in the -10 to -14 C range.  The LCL was relatively high in the 1000-1500 meter range.  Downdraft CAPE was between 1400 and 1700 J/kg and there was a significant amount of CAPE in the -10 to -30 C layer of the atmosphere of 1000-1600 J/kg.  The atmosphere was weakly sheared with 25 to 35 kts of effective shear.  Shear in the zero to 3 km layer was between 50 and 250 J/kg, resulting in considerable rotation of thunderstorm cells.  The freezing level was quite high, at 14,000 feet.  Considerable moisture was available through a deep layer of the atmosphere with precipitable water values of 1.75 to 2 inches.  Thunderstorms developed over the northwest part of Iowa by early afternoon.  The storms became severe and dropped southeast into the most unstable air to the east and south of the complex.  The primary mode of severe weather with this event was in the form of high winds and hail.  Some of the hail reached golf ball in size, however with the warm atmospheric conditions much of the hail remained below severe levels.  High winds were reported all along the leading edge of the thunderstorm complex, with numerous reports in the 60 to 70 MPH range.  There were two areas where the most significant damage occurred.  The first was in the Waterloo, Cedar Falls, and Hudson areas of northeast Iowa.  A beta bow element pushed into the area resulting in more widespread wind damage.  Some of the damage was similar to what one might expect with a weak tornado.  The second area was over Dallas County.  High winds caused considerable damage from around Dallas Center, west to the county line.  An old airport field was hit by the winds with considerable damage to equipment and hangars.  Winds were estimated to be at least 80 MPH.  Later in the event, some of the storm cells collapsed with a local high wind event occurring in Hamilton County.  Two semi-tractor trailer trucks were blown over on Interstate 35 between mile post 162 and 165 in Franklin County.  There were numerous reports of wind damage around Franklin County.  Trees were blown down onto cars and houses.  Another semi-tractor trailer was blown off the highway just east of Perry on Highway 44 in Dallas County. Very heavy rain fell with the storms as well.  There were numerous reports of urban and small stream flooding.  Flash flooding took place in Dallas County, primarily in the Waukee area.
