For the fourth day in a row a frontal boundary found itself primarily stalled out and draped across Iowa.  This time the front found its way across southern Iowa and initiated a couple of severe storms within an environment of around 2000 J/kg MLCAPE and supportive effective bulk shear in excess of 40-50 kts.  As a result, the storms that did initiate went organized and severe rather quickly.  Severe hail was quickly produced and on its way to the very large category.  The largest hail reports of around 3 inches were in and around Centerville.
