...FUNNEL CLOUDS SIGHTED OVER PORTIONS OF CENTRAL ILLINOIS...
Atmospheric conditions exist today across portions of central
Illinois that favor the possible formation of weak circulations on
a pre-existing boundary. Some of these circulations are occurring
underneath developing showers, where a funnel cloud may develop.
Once the rain begins, the funnel cloud 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.
Instructions:
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.
