Non-Severe Funnel Clouds Possible Thursday Evening

A wind shift line occurring over Northern Illinois due to a trough of low pressure (elongated area of low pressure) could help produce a few non-severe funnel clouds early this evening.

There was one observed funnel cloud in La Salle County, near Sheridan, shortly after 6pm Thursday evening.  Don't panic, because atmospheric conditions are not favorable for any of these funnels to turn severe and they usually don't last.  The funnel clouds usually lower a few hundred feet down from the cloud, rotate or spin like a top for a few minutes and then usually dissipate.

These type of funnels clouds rarely touch the ground and usually don't pose any threat as the atmospheric conditions are not favorable for long lasting funnel clouds, or tornadoes.
