... Showers with possible funnel clouds will affect DeKalb... Kane... northern Kendall... southeastern Ogle... southeastern Winnebago... southern Boone and southern McHenry counties...
At 358 PM CDT... showers with possible funnel clouds were located near Sycamore. The showers were moving southeast at 25 mph. Other showers were near south of Marengo Illinois... just southeast of Rockford and just east of Belvidere Illinois.
Some of the showers may produce funnel clouds or landspouts. These are not the tornadoes produced by larger supercell thunderstorms. However... if one of these funnel clouds or landspouts touches the ground... some minor damage could occur. If you see one of these funnel clouds... be prepared to seek shelter in a strong reinforced building.
