Episode Narrative An unseasonably warm airmass overspread Iowa during the day on the 13th. Maximum temperatures reached the mid 80s to low 90s across the state. Dew point readings were in the upper 50s to low 60s. A weak frontal boundary extending north-northeast to south-southwest advanced into the state during the late afternoon. The airmass had become very unstable with Lifted Indices in the -5 to -8 range. CAPE values reached 3500 by the late afternoon hours. Thunderstorms erupted late in the afternoon and became severe very quickly. The main mode of severe weather with the storms was large hail. The freezing level was around 12,300 feet. Though quite high for mid April, it was easily low enough to make hail production easy. Several of the storms exhibited the structure of a tornadic supercell. The LCL was quite high however, at around 7300 feet. This limited the development of tornadoes somewhat. One tornado touched down in Tama County, northeast of Toledo. The tornado was on the ground briefly and touched down in an open field. No damage was reported with the tornado. Many of the storms produced large hail. There were numerous reports of one to two inch diameter hail. A couple of the storms produced very large hail. Hail of tennis ball to base ball size was reported in Hardin County south of Radcliffe and southwest of Hubbard. The same storm that produced the brief tornado touchdown in Tama County also produced hail of two and one half inches in diameter east of the Traer area.
Event Narrative Tornado touched down briefly in open fields northeast of Tama. No damage occurred.
