Minor crop damage occurred. Scattered severe thunderstorms developed along a warm front extending across central Illinois during the late afternoon and evening of September 9th. A Mesoscale Convective Vortex (MCV) associated with a complex of thunderstorms that had developed the previous night across Kansas interacted with the boundary to greatly enhance low-level wind shear across east-central Illinois. As new thunderstorm cells developed and moved into this area of stronger shear, many of them began to rotate. Four tornadoes touched down across portions of Champaign, Vermilion, and Clark counties between 6:30pm CDT and 7:15pm CDT, including an EF-2 tornado that produced considerable damage across southern Champaign County. KNOX COUNTY --- HENDERSON [41.02, -90.35] 09/21/16 11:45 CST 18K Thunderstorm Wind (EG 52 kt) 09/21/16 11:50 CST 0 Source: Trained Spotter Several 1-foot diameter trees were blown down and shingles were torn off a roof in Henderson. A large complex of nocturnal thunderstorms that had developed over the Upper Midwest during the night of September 20th dropped southward and weakened considerably as they tracked into north-central Illinois around midday on September 21st. While most of the storms produced wind gusts of 40-50mph along the associated gust front, enhanced winds of up to 60mph possibly associated with a gustnado caused some minor wind damage in the town of Henderson in northern Knox County.
