The episode as NWS DMX wrote it up.
The airmass over Iowa remained very unstable with a persistent frontal boundary extending east to west across the central part of the state. Temperatures rose into the mid 80s to low 90s south of the front with dew point readings in the low 70s. The airmass was capped with 700 mb temperatures around +12 C much of the day. Thunderstorms erupted during the evening hours over northeast Iowa. Most of the storms remained below severe limits, however one cell did drop nickle size hail in Black Hawk County at Hudson.
