Summary of April 9, 2017 Large Hail Reports

Overview

Warm and humid conditions, for early April, led to the eruption of numerous thunderstorms Sunday afternoon and evening, April 9th. Some of those storms became severe, producing large hail from north central Iowa, across southeast Minnesota, into north central Wisconsin.

Hail ranged from the size of pennies all the way up to tennis balls, with the largest hail report occurring just north of the town of Stacyville, Iowa in Mitchell County. There were lots of reports of hail, without much rain or gusty wind.
