Overview
|
Scattered showers and thunderstorms tracked across portions of eastern Iowa and northern Illinois the evening of April 15, as a cold front pushed east across Iowa. Large hail, heavy downpours, and frequent lightning were common as the storms rolled through. A tornado was also confirmed from a strong storm that tracked across Jones County, which produced damage to trees and farm outbuildings. Widespread hail reports between peas and dimes, and rainfall amounts between a half inch and 3 inches were found in Benton, Linn, Johnson, and Clinton counties. High temperatures were in the upper 70s and lower 80s area wide. |
