Thunderstorms that started before dawn triggered some storm sirens to sound in Quad City-area communities.
Rock Island and Moline residents reported hearing the sirens before 2 a.m. Thursday, April 3, 2014.
StormTrack 8 Chief Meteorologist James Zahara said possible large hail in the storms was the likely trigger for the sirens.
A trained weather spotter reported 1.2 inches of rain fell during early-morning storms in Galva, Illinois according to the National Weather Service office in Davenport, Iowa.
Similar rain amounts were reported south of Burlington as well as in Princeton and Kewanee, Illinois.
Dime- and penny-sized hail was reported by a trained spotter just after 2 a.m. in Rock Island County. Officials reported similar-sized hail just before 2 a.m. just east of the airport in Burlington, Iowa.
Spotters and residents also reported hail the size of ping pong balls and golf balls in northwestern Adair in McDonough County.
Damage was also reported to vehicles in Wapello after hail that measured about 1.75 inches fell there.
