A very unstable airmass moved into Iowa during the day on the 29th as a warm front lifted north into the state during the afternoon.  Low pressure approached from the west, along with a cold front so that the triple point was near the western Iowa, eastern Nebraska area by late afternoon.  Thunderstorms erupted quickly during the late afternoon and evening hours in the unstable airmass.  By evening, the low level jet was in the 40 to 60 kt range, feeding moisture into the state and pushing precipitable water values to around 200% of normal, in the 1.5 to 1.8 inch range.  MUCAPE reached 3000 to 3500 J/kg over western Iowa, with lifted indices in the -6 to -10 C. range.  The freezing level was quite high, limiting the hail size somewhat with this event, at 14,300 feet.  The available CAPE in the -10 to -30 C. layer of the atmosphere was in the 300 to 500 J/kg range.  The DCAPE was between 800 and 1000 J/kg.  The environment was highly sheared with 50 to 65 kts of shear available during the event.  The LCL was also quite low, in the 750 to 1250 meter range.  Thunderstorms erupted over western Iowa stretching into north central Iowa first.  It did not take long for the storms to become severe with hail and high winds.  Most of the hail reported was in the pea to marble size, with the larger stones in the nickel to quarter size range.  The primary mode of severe weather was high winds and several tornadoes.  The secondary, but significant threat, was heavy rainfall.  A band of 3 to 5 inches of rain fell between U.S. Highway 30 and U.S. Highway 20 during the event.  The heaviest rainfall total was in Greene County at Jefferson, with 5.90 inches.  Tornadoes began to touch down in western Iowa in Crawford County with two brief touchdowns.  One was west of Dow City, causing roof and shingle damage to a farmhouse there.  The next was east of Denison where a barn roof was removed and a trailer house was destroyed.  A tornado in Carroll County caused damage to 3 farmsteads southeast of Templeton.  A machine shed was completely destroyed and numerous other buildings sustained damage.  Trees also had substantial damage. Two tornadoes touched down in Calhoun County.  One near Farnhamville, tore the roof off of a home and downed power lines.  The second caused damage to trees, outbuildings, and power lines on four farmsteads.  Farther south, a brief touchdown was reported in Dallas County in open fields west of Minburn.  Another tornado touched down in Dallas County later on, west of Adel, and was on the ground for about 4 miles.  A more substantial tornado touched down near Murray in Clarke County with one reported on the ground for about 9 miles.  As the storms moved east, another tornado was on the ground for over 10 miles in Warren and Marion Counties.  The most significant tornado occurred in Marion and Mahaska Counties where an EF2 tornado was on the ground for about 18 miles.  Several homes were damaged along its path, two mobile homes were destroyed, and considerable damage was done to trees in the area.  Up to 10 people were injured with this tornado, mainly in Attica.  The official damage count from this tornado included 5 homes destroyed, 15 with major damage, and another 25 with minor damage.  Many of the storms produced high winds with several reports of winds in the 65 to 75 MPH range.  Considerable tree damage was reported and some structural damage, mainly outbuildings and shingle damage.  Two cars were blown off of the road east of Manning by the high winds.  Building debris was blown onto Highway D60 near Gowrie, causing a brief closure.  High winds in Butler County blew down a machine shed and barn southwest of Aplington, very near to where an EF5 tornado struck just days before.  Extensive damage was done to a farmstead there with some damage done to the house itself as well.  Lightning struck a man in Carroll.  The lightning bolt hit his driveway, blowing out a chunk of concrete out of the driveway and also injured the man.  He was taken to hospital, treated, and released with minor injuries.  Flooding became a significant issue after the heavy rainfall of the previous few days.  Extensive river flooding occurred across the central third of the state.  Record crests were recorded on the Iowa River at Marshalltown.
