Special Statement
Alert issued: Fri, Jun 22, 2018 04:56 PM
In effect until: Fri, Jun 22, 2018 09:00 PM
...Cold air funnels possible today...
generally funnel clouds and tornadoes develop and occur in
conjunction with conditions that produce severe thunderstorms.
There are weak showers and thunderstorms in the area, but little
potential for actual tornadoes with only weak wind shear.
Research studies of funnel cloud occurrences indicate that a
different type of funnel cloud forms when weather conditions are
similar to those of today. These are called cold air funnels and
are not as violent as those associated with severe thunderstorms.
Cold air funnels are associated with thunderstorms or showers
that form in deep...cold core...large-scale low pressure systems
such as the one overhead today. These funnel clouds are smooth
and narrow. The parent storm or shower is not particularly tall or
intense. These funnel clouds normally protrude a few hundred feet
downward from the parent clouds...rotate or spin like a top...and
last only a few minutes before dissipating.
In rare cases when their circulations does reach the ground...
cold air funnels cause only minor damage. More reports of small
funnel clouds are possible over central Indiana today. Warnings
may be issued if any of them touch the ground for an extended
period of time.
