A strong push of theta-e took place during the early morning hours.  A stationary frontal boundary remained south of Iowa, setting the stage for another MCS to develop.  The airmass was relatively unstable with CAPE around 2000 J/kg just south of the front.  The low level jet was not real strong, in the 25 to 30 kt range.  Thunderstorms developed after midnight over eastern Nebraska.  The storms moved into southwest Iowa and lifted northeast into the central counties during the predawn hours.  The storms accelerated as they moved through Iowa, producing high winds across the southern third of the state.  Trees and power lines were toppled.  Damage was reported to roofs in Taylor and Clarke Counties by the high winds.  Heavy rain fell in the Ottumwa area, with reports of 2 inches in one hours time.  Flash flooding occurred in part of the city with 2 feet of flowing water reported in parts of the downtown area.
