# HEADLINE -------------------- FUNNEL CLOUDS SIGHTED OVER CENTRAL ILLINOIS # SUMMARY -------------------- Atmospheric conditions exist that favor the possible formation of weak circulations along a pre-existing boundary. Some of these circulations are occurring underneath developing showers and thunderstorms, where a funnel cloud may develop. Once the rain begins, the funnel cloud usually dissipates. Low hanging clouds can also appear to dip up and down at times, but they will not show signs of any rapid rotation. An actual funnel cloud will exhibit spinning in a counter-clockwise direction. In rare instances these funnels may briefly touch down. Stay alert and be prepared to move to a safe shelter if a funnel cloud approaches the ground. # DETAILS -------------------- ISSUED AT Saturday, June 27, 2026 at 7:00 PM CDT ISSUED BY National Weather Service Lincoln IL HEADER Special Weather Statement # AREAS AFFECTED -------------------- Moultrie, Champaign, Christian, Douglas, Macon, Morgan, Piatt, Sangamon, Scott, Shelby, Vermilion Including the cities of Monticello, Champaign, Urbana, Danville, Winchester, Jacksonville, Springfield, Taylorville, Decatur, Sullivan, Tuscola, and Shelbyville
