Episode Narrative A strong upper level low pressure was tracking southeast across South Dakota during the day. Iowa was on the edge of the cool pool associated with this low. Severe parameters were not all that strong. During peak heating, there was an increase in 0-1 km storm relative helicity and the shear values did increase to around 30 kts. A line of thunderstorms formed along the edge of the cooler air. One of the storms produced a brief tornado in Hamilton County just west of Ellsworth. The tornado touched down in open area and caused little damage. There were also several reports of funnel clouds around Hamilton and Grundy Counties.
