What happened
The episode as NWS DMX wrote it up.
Strong low pressure intensified over the Rockies. A warm front developed from the low, east into Iowa. Strong warm air advection and a surge in moisture took place as dew points in the low tomid 60s were drawn over the top of the frontal boundary. Thunderstorms formed north of the frontal boundary. Most of the storm were not severe, but did lay down a band of significant rainfall of three quarters of an inch to over an inch, along with some small hail. One storm became severe shortly after sunrise with hail of three-quarters of an inch in diamerter falling south of Waterloo in Black Hawk County.
