Peak Winds 125 MPH Path Length 18.25 miles Max Width 100 yards Injuries/Deaths 0/0 Summary: A strong tornado developed around 7 miles southeast of Vandalia, Illinois around 4:20 PM CDT and traveled northeast to the Fayette/Effingham County line by 4:34 PM CDT. The first tornado damage observed was near the intersection of E1050 Avenue and N1375 Street where a greenhouse lost portions of its roofing material and suffered other minor damage. The tornado continued northeast toward Gatch Lake causing damage to several outbuildings and one single family residence. The width of the tornado increased to nearly 100 yards wide and the strength increased from EF0 to EF1 during this time period. The tornado continued northeast causing mainly tree damage until it reached a farm along E1200 Avenue near N1780 Lane. Here a barn and several silos were destroyed, along with a single wide mobile home. The damage was rated EF2. Thankfully there were no occupants in the mobile home at the time of the tornado. The tornado continued northeast destroying another outbuilding, with the debris being tossed down wind hundreds of yards into the open field. The greatest tornado damage occurred to a residence near the intersection of Illinois Highway 185 and E1250 Avenue. The tornado destroyed their garage, ripped their roof and southeast walls off of their home. This damage was also rated EF2 with winds estimated to be 125 mph. The tornado began to weaken as it moved northeast only causing minor damage to an outbuilding and downing trees in a narrow path, less than a hundred yards wide, to the county line.
