A very dynamic weather pattern was in place over the central U.S. on the 3rd.  A strong short wave moved out of the Rockies onto the Plains during the day.  Thunderstorms formed early in Nebraska and South Dakota.  The storms spread and developed southeast into Iowa during the afternoon and evening.  The airmass became unstable with CAPE values rising to about 2000 J/kg.  Downdraft CAPE rose to to around 1000 J/kg, with about 600 J/kg of CAPE available in the -10 to -30 layer of the atmosphere.  The freezing level was around 14,000 feet.  The atmosphere was highly sheared with 50 to 80 kts of shear available.  A strong 70 to 80 kt mid level jet moved into the area as the low level jet increased to around 60 kts by evening.  Precipitable water values were around 2 inches, which is more than three sigma above seasonal normals.  The LCL level was fairly low, around 1000 meters. Thunderstorms that formed to the west quickly became an upscale MCC as it continue southeast.  The strongest storms formed along the baroclinic zone of the warm front.  Windspread severe weather occurred, but was limited to the far southwest part of the CWA.  Hail and high wind was the mode of severe weather with hail up to baseball size and winds in excess of 80 MPH.  The winds caused considerable structural and tree damage across southwest Iowa.  Whole farm buildings were destroyed in Taylor and Ringgold Counties with winds of 70 to 95 MPH.  Very heavy rainfall also occurred with a band of three to six inches of rain.
