The National Weather Service reports that cold air funnels were sighted notheast of Urbana about 6 p.m.
This feature was part of a line of showers moving southward through Champaign and Vermilion counties.
Atmospheric conditions exist across far eastern Illinois that favor the formation of the phenomenon called cold air funnels. Cold air funnels are normally not associated with thunderstorms.
They form out of the bottom of clouds, spin, and dip down to within several hundred feet of the ground.
The cold air funnels may last for several minutes, occur a number of times during the afternoon, and remain in the same general area. They
normally dissipate completely toward sunset.
In rare instances funnels may briefly touch down.
Stay alert and be prepared to move quickly to a safe shelter if a funnel cloud approaches the ground.
