The path drawn at its surveyed width of 20 yards (0.01 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

What EF0 means. On the Enhanced Fujita scale, EF0 is light damage: shingles and siding peeled, gutters torn, branches broken, consistent with estimated gusts of 65–85 mph. The rating comes from a survey of the worst damage after the storm, not from a wind measurement, so it says as much about what the tornado hit as about how strong it was.

What the National Weather Service wrote

A brief landspout tornado developed along the outflow boundary of a cluster of thunderstorms just north of Chester, IL. The landspout formed just east of Bodes Ln and tracked eastward, impacting several trees and two outbuildings before dissipating in an adjacent field.

The wider storm

Numerous thunderstorms developed ahead of a cold front during the afternoon of August 30th. Due to a modest instability - low wind shear environment, these thunderstorms were pulse in nature with wet microbursts being the primary threat. Although an abundance of microbursts occurred, only one was severe in Macoupin, producing tree damage. A landspout also developed along outflow passing through Randolph County, producing minor damage along its path.

Began near Menard (37.9389, -89.8463).
