A strong surge of very moist and unstable air moved into Iowa as a warm front stretched east to west along the Iowa/Missouri border.  By the late afternoon hours, MUCAPE was in the 3000-4000 J/kg range with lifted indices between -5 and -8 C.  Downdraft cape was between 800 and 1300 J/kg with an effective shear of 45 to 50 kts.  Available CAPE in the -10 to -30 C. layer of the atmosphere was between 200 and 400 J/kg.  Thunderstorms erupted by the evening and a cyclic supercell developed over southwest Iowa.  By the time the night was done, three separate supercells took a similar track across southern Iowa.  The LCL was quite low, between 500 and 1000 meters.  Several tornado reports were received from Adams into Clarke Counties.  The storms also produced winds of 60 to 70 MPH in places, with the strongest winds late in the event.  A gust of 77 MPH was recorded in the Pella area.  Winds northwest of Baxter flipped a propane tank.  Hail was limited in size by the freezing level of 13,500 to 14,000 feet.  The exception was during stronger periods of the supercell's life.  At on point, golf ball to baseball size hail was reported in Union County.  A cluster of thunderstorms formed over northern Iowa as well.  Severe weather was isolated with this area of storms.  Copious amounts of rain fell with the storms, both the supercells and the cluster across the north.  Flooding became widespread with numerous reports of water over the roads along the track of the supercells, and also over parts of north central into northeast Iowa.  The heaviest rainfall occurred over southwest Iowa, where northwest of Creston picked up nearly 8 inches of rain.  Following the heavy rainfall of the previous night, Iowa Governor Chet Culver declared state disaster areas in both Union and Humboldt Counties.  Seven tornado touchdowns occurred.  Four of them were EF1 in strength and had path lengths ranging from 4 to 11 miles.  Three of the tornadoes touched down in Adams County and four in Union County.  The final tornado in Union County crossed into Clarke County shortly before dissipating.
