July 10th Tornado/Severe Weather Event

Overview

Thunderstorms developed rapidly in west central Illinois from about Monmouth to northwest of Peoria during the late afternoon of July 10th. The storms interacted with a front which was draped from northwest to southeast nearly parallel with I-74. One storm produced a tornado in northern Peoria County around 5:45 pm. Other thunderstorms rapidly clustered together and sank southward, producing large hail and damaging winds gusts in parts of central Illinois between 6:30 pm and 11:00 pm.

Hardest hit areas included locations from southwest of Peoria - near Hanna City - toward northern Fulton County, down to Lincoln and much of Logan County.

Wind & Hail:

Wind

Extensive wind damage was done in the city of Lincoln between 8:10 and 8:35 pm CDT on July 10th. Wind gusts of around 60 mph were measured throughout the city. Doppler radar indicated areas just north of Lincoln may have had winds in the 70 to 80 mph range. Several downbursts were the cause of the wind damage to power lines, power poles, hundreds of trees, crops, and structures damaged by falling trees. Northern parts of Logan County sustained wind damage between 7:55 and 8:10 pm, and southern Logan County had wind damage between 8:35 and 8:55 pm.
