Episode narrativeepisode_narrativeA low pressure area tracked east out of South Dakota during the afternoon and evening. A warm front extending from the low across west central into southeast Iowa lifted north with thunderstorm development during the afternoon. Thunderstorms formed during the late afternoon and overnight hours as the cold front trailing form the low moved into Iowa The atmosphere became moderately unstable during the afternoon and evening as moisture continued to pool near the warm front and ahead of the low. Precipitable water values increased to 1.8 inches by evening. The CAPE increased to 2000 to 3000 J/kg with 600 to 900 J/kg available in the -10 to -30 C layer of the atmosphere, though the freezing level was quite high at 15,000 feet. Downdraft CAPE was in the 800 to 1000 J/kg range. The atmosphere had 40 to 50 kts of shear available. Thunderstorms moved into western Iowa and became severe. Initially the storms produced hail. Most of the hail was in the 1 to 1.5 inch range, with a few locations approaching 2 inch diameter hail. Upscale development took place with the storms developing into an MCC before midnight. The storms then became producers of high high winds and heavy rainfall. A 67 MPH wind gust was recorded in the Carroll area. One storm west of Pocahontas produced a 2 mile long narrow path of damage as microburst winds estimated around 90 MPH damaged several houses. Roofing was lost with debris embedded in exterior walls. Farm equipment was also blown over. Flash flooding took place in west central Iowa and parts of central Iowa as reports of 3 to 7 inches of rain in some locations produced flash flooding. Many highways were closed by high water, and countless county roads were flooded in Carroll, Guthrie, Greene, and Madison Counties. Subsequent flooding in Madison County caused considerable damage with several bridges washed out or underwater northwest of Bevington.
