What happened

The episode as NWS DMX wrote it up.

A cold front dropped south out of Canada during the day and reached southern Iowa by the late afternoon hours. Temperatures warmed into the low to mid 80s ahead of the front with dew point readings in the upper 50s to low 60s. CAPE was marginal with only 1000-1500 J/kg available. The freezing level was quite low, running between 10,000 and 10,500 feet. Thunderstorms erupted along the front during the late afternoon hours and produced some marginally severe hail as they passed. The largest hail was an inch in diameter. Hail fell for 5 to 10 minutes in Warren County at Norwalk, and covered the ground in Taylor County northwest of Blockton.
