Bulletin details
At 315 PM, broadcast media and Emergency Management personnel reported additional funnel clouds over parts of central Illinois. Atmospheric conditions exist that favor the possible formation of weak circulations along pre-existing boundaries. 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.
