What happened

The episode as NWS DMX wrote it up.

A very dynamic synoptic situation was in place over the central U.S. during the day on the 29th. Warm and moist air was in place over Iowa with high temperatures for the day reaching the upper 80s to low 90s across the area. Surface dew point readings rose into the low to mid 70s by the early evening hours. This resulted in a very unstable airmass over the state with lifted indices in the -10 to -12 C. range and CAPE values in the 4500 to 5000 J/kg range. The airmass was quite warm with freezing levels in the 14000 to 15000 foot range. A closed upper low lifted northeast out of the central Rockies during the afternoon and evening. Surface low pressure lifted northeast across Nebraska, northeast into eastern North Dakota. A cold front trailing south from the low approached the state by the early evening hours. During the day, scattered convection broke out over the state. Clearing spread northeast as the upper level dry slot pushed northeast into the central U.S. Upper level winds increased in response to the approaching low with 500 Mb winds around 75 kts by the mid evening hours. Thunderstorms erupted quite rapidly during the early evening hours. Once initiation began, thunderstorms spread quickly in the unstable airmass. Mid level lapse rates were around 8 degrees C, which aided in thunderstorm development. With freezing levels quite high, hail was not a major factor with the storms. There were spotty reports of three quarter inch diameter hail to nickel size hail. Though hail was limited, a report indicated that hail fell hard enough in Warren County at mile post 44 along Interstate 35 that motorists were unable to see the road. The main mode of severe weather winds high wind. Reports of 60 to 75 MPH winds were very numerous. The highest winds recorded was in Union County west of Thayer with a measured gust of 81 MPH. Numerous trees were downed by the storms with power outages reported around the state. High winds destroyed a 40 x 80 foot storage building west of Manning in Crawford County. Another storm a camper in Boone County at Boxholm. In Hamilton County a semi-tractortrailer truck was blown over at the Flying J Truck Stop in Stanhope. Scattered reports of barns and grain bins being destroyed by the high winds were received. In Jasper County, some of the stronger winds occurred as the storm pass through areas east of Baxter. Winds of around 85 MPH blew down numerous trees. blew down an anchored corn crib, a machine shed, and blew hard enough to blow an air conditioning unit through the window into a house.
