Low pressure developed over Kansas with a strong southerly flow of very moist air streaming into Iowa ahead of it.  Surface temperatures warmed into the 80s with dew point readings in the low to mid 70s.  A semi-stationary front extended northeast from the low, across northern Iowa during the afternoon into the evening hours.  The atmosphere became very unstable with MUCAPE in the 4500 to 5000 J/kg range by mid afternoon and lifted indices around -7 C.  The shear was quite high, between 40 and 70 kts.  Downdraft CAPW was between 1000 and 1300 J/kg with cape in the -10 to -30 C. layer of the atmosphere around 400 J/kg.  The LCL was in the 750 to 1000 meter range, with the lowest over north central Iowa.  With the exception of one hail report of 3 inch diameter hail report in north central Iowa, hail size was somewhat limited by the freezing level of 15500 to 16500 feet.  A very strong transport of moisture took place on a 50 to 75 kt 850 mb jet.  Precipitable water values soared to 1.6 to 1.9 inches by evening.  During the initial phase of the severe event, high winds and hail were reported along the line of thunderstorms that formed from northern into west central Iowa.  There were four reports of tornadoes in Worth, Winnebago and Cerro Gordo Counties during the afternoon hours of the 7th.  This was with the initial round of storms.  One of the tornadoes in Winnebago County destroyed a hog confinement building containing 3500 hogs.  Several of them were killed and the remaining hogs needed to be taken to slaughter.  The event transitioned into a flooding event overnight, then tornadoes began again during the afternoon of the 8th.  A tornado touched down in Taylor County.  Windows were blown out of houses there and several trees were twisted and blown down around the house.  A pole shed was completely destroyed south of Ferguson in Marshall County.  A stronger tornado was on the ground north to northeast of Ottumwa.  A home lost a roof, with a wall of one room partially collapsed by the tornado.  Several trees were also downed around the home.  The event transitioned into a major Flood/Flash Flood event during the evening and early morning hours with many locations reporting 1 to 2 inches of rainfall, and spotty amounts of around 5 inches in just a few hours time.  The line moved very little for a period of several hours.  During the predawn hours, the line became broad and weakened to generally below severe limits.  A new round of thunderstorms from Nebraska, which was the southwest part of the extensive line, moved into  west central and southwest Iowa.  The storm generally remained below severe levels for the most part, but they did produce very heavy rains.    Another line of thunderstorms formed/re-intensified along the frontal boundary by the early afternoon hours.  Initially, the storms produced strong winds and some small hail.  As they moved southeast, several reports of high winds to near 70 MPH and a few reports of tornadoes were received.  The most significant weather feature with this event was the heavy rainfall.  The antecedent soil conditions in Iowa were extremely wet, such that flash flooding was caused by rainfall of an inch or more in an hour, even in rural areas.  Heavy rainfall of 3 to 6 inches occurred in a broad swath extending from west central into north central, and parts of central and northeast Iowa.  This resulted in widespread flash flooding.  Eventually, the rain lead to major to record flooding along many of the rivers in the state.  At one point or another, about 40 of the DMX 51 counties in the CWA were under flash flood warning.  The situation was very serious over the north central and northeast counties.  A levy was breached in the Mason City area as the Winnebago River rose to 3 feet over the record stage.  The city was inundated by water.  The water treatment plant was under water and non operational, all power was lost to the power grid in the city.  The river cut a new channel and changed course into the downtown area.  In the New Hartford area, a dam broke on Beaver Creek, resulting in the water level rising 2 feet above the all-time record level.  High water along the mainstem Cedar River also caused communities to lose water.  Nashua lost water as the water plant became flooded.  Flooding along the Shell Rock River resulted in water supply loss in the town of Rockford.  There was one death that resulted from the flooding.  A 33 year old man died as he drove into flood waters in Interstate 35 at mile post 141 in Hamilton County.  A second death occurred in Wright County as a 50 year old male farmer near Galt was sucked into a culvert by flood waters as he checked the field tiles in his farm field.
