A very warm airmass moved into Iowa on the 11th and 12th of April.  By the afternoon of the 12th, temperatures reached the 80s across a large part of Iowa with dewpoint temperatures in the mid 50s to around 60.  A cold front moved into Iowa during the afternoon and tracked southeast across the state during the evening and overnight hours.  The atmosphere became unstable with CAPE values increasing to 2000 to 2500 J/kg by late afternoon.   Downdraft CAPE rose to between 800 and 1200 J/kg, while CAPE in the -10 to -30 C layer of the atmosphere was in the 400 to 500 J/kg range  The freezing level was around 12,000 ft near the storms inception point.  Precipitable water values increased to just over an inch by evening.  The atmosphere was strongly sheared with 40 to 60 kts of effective shear available.  Thunderstorms were initially capped off during much of the afternoon with only scattered storms forming along the front. The cap was broken by late afternoon into the evening. A line of strong to severe storms formed.  The primary mode of severe weather was hail with most storms producing at least some hail.  There were numerous reports of golf ball size hail.  A few of the storms produced larger hail, with 2.5 inch diameter hail reported in Story County, and 2 inch diameter hail in Butler and Bremer Counties.  After sunset, the storms began to produce severe winds with several gusts to around 60 MPH reported over the southeast third of the state.  As the winds increased, the hail became smaller.  Significant damage was done in Mahaska County by the strong winds.  Heavy straight-line winds caused several thousand dollars in damage to a farm.  The barn roof was damaged, a south wall partially gone, overhead door destroyed and wrapped around a trailer, skylights blown out, north wall section bowed out, and a 12' X 14' door was blown off. Three fruit trees were also blown down.  Roof damage was reported in Wayne County as very strong straight-line winds swept through the Promise City area.  In addition, a large shed was blown down by the winds south of Corydon.  During the night into the next morning the storms became multi-cellular and began to train over the state as the next shortwave advanced northeast toward the central U.S.  Locally heavy rain was reported with a 3.5 inch total in a 6-hour period reported in Clarke County of south central Iowa.  Twenty-four hour rainfall totals in Jasper and Poweshiek Counties were around 4 inches.  Two-day totals across much of the southeast half of Iowa were in the two to five inch range.
