Episode narrativeepisode_narrative	After a rather chilly overnight, complete with reports of up to 3.5 inches of snow in northern Iowa, storms initiated across portions of central Iowa and produced multiple instances of severe hail. \|\|Throughout the day, surface high pressure centered over the state slid eastward, placing the western half of the state back in warm air advection by the evening hours, especially above surface levels. The environment was not extremely conducive to sustained severe weather, but did have indications of hail potential, including a freezing level below 10kft, moderate to steep lapse rates above the near surface inversion, and a few hundred J/kg CAPE in the hail growth zone. Elevated storms roughly initiated along the 850mb front along and near I-80 across western Des Moines and west of the metro area. Storms were not long lived, but were able to produce a number of reports of severe hail, including up to half dollar in size.
