...Funnel Clouds Possible Early This Evening...

Atmospheric conditions are favorable for the development of funnel
clouds early this evening. These funnel clouds normally only
protrude a few hundred feet downward from the parent cloud, rotate
or spin like a top, and last a few minutes before dissipating.

Funnel clouds early this evening are most likely to occur along a
weak, slow moving cold front which was drifting slowly south along
a line from near Dixon, to Minooka and Peotone Illinois and Hebron
Indiana. Funnel clouds will become less likely with the approach
of sunset and the loss of daytime heating.

These funnel clouds rarely touch the ground and typically do not
pose any sort of hazard. The atmospheric conditions that these
funnel clouds develop in do not support strong, damaging
tornadoes. However, on extremely rare occasions, these funnels can
briefly touch the ground and produce very minimal, if any,
damage.

If threatening weather approaches, move indoors to a place of
safety. The National Weather Service will continue to closely
monitor the situation.
