Episode narrativeepisode_narrativeA cold front was stretched east-northeast to west-southwest across the far southeast corner of Iowa. Soundings indicated precipitable water values approaching 2 inches with CAPE values of 2500 to 3000 J/kg and lifted indices around -6. Though the bulk of the thunderstorm activity formed south of the boundary in Missouri, a band of elevated convection developed over southwest into central Iowa. A few of the storms became severe and exhibited left moving and anti-cyclonic rotation characteristics. The left movers produced hail with several reports of three quarter to one inch diameter hail received. One golf ball size hail report was received in Jasper County northeast of Reasnor. Hail the size of quarters pelted areas north of Osceola. The hail reportedly covered the ground 7 miles north-northwest of the city of Osceola. Lightning struck a teen-ager in West Des Moines. The teen and a friend were running for cover in the rain when he was struck by lightning. He was rushed to the hospital and was reported in critical condition on the evening of the 27th.
