The frontal boundary that moved through the state during the previous night retreated northwest and allowed the atmosphere to reload.  CAPE rose to 2000 to 3000 J/kg by mid morning with downdraft CAPE values in the 1400 to 1600 J/kg range and available CAPE in the -10 to -30 layer of the atmosphere around 500 J/kg.  The freezing level fell slightly from the previous night and was around 13,500 to 14,000 feet.  Lifted indices were only in the -1 to -3 C range.  The shear was about the same as the previous night, in the 20 to 35 kt range, however precipitable water values fell to 1.1 to 1.5 inches.  As the warm air returned, thunderstorms developed before dawn.  They increased in strength as a weak shortwave approached the area.  The thunderstorms formed into a cluster over northeast Nebraska into western Iowa after sunrise.  The small MCS took on a mini bow type configuration.  Though there were a few reports of hail of up to an inch in diameter, the primary mode of severe weather was high winds from the bowing system.  Wind speeds of 60 to 80 MPH were common along the leading edge of the storm.  Tree damage was widespread over a several county wide area.  Some property damage was done by the winds as well due to flying debris.  The thunderstorms continued southeast into southeast Iowa during the late morning and early afternoon and weakened slowly.  Another line of thunderstorms formed over northwest Iowa by late morning and continued into the mid afternoon hours.  These storms produced high winds, heavy rainfall, and hail.  The hail was generally around an inch in diameter, with the largest being golf ball size in Webster County.  Golf ball size hail also fell in Warren County at Milo.  Wind speeds were in the 60 to 65 MPH range for the most part, resulting in tree and power line damage.  A tornado touched down in open fields in Madison county north of St Charles.  The heavy rainfall resulted in some flash flooding as well.  Soil conditions across the state were nearly saturated, so a quick 1 to 2 inches of rainfall caused local flash flooding in Black Hawk, Marion, and Tama Counties.
