June 27, 2011 Funnel Clouds, Wind Damage and Weak Tornadoes
Several small clusters of thunderstorms during the evening of June 27th, 2011,
produced numerous funnel clouds and a few confirmed tornadoes. There was
also some isolated wind damage.
Storms began developing during the early evening hours as a weak weather disturbance
crossed Indiana into Ohio, and interacted with an extremely moist and moderately
unstable airmass. Dewpoints well into the 70s allowed for very low cloud bases, which
aided in the viewing of numerous funnel clouds that developed with the storms. The
funnels, for the most part, were extremely photogenic given the lighting near sunset.
Storms quickly weakened with the loss of daytime heating, and diminished below severe
levels by late in the evening.
Numerous tornado warnings were issued due to the volume of funnel cloud reports
and associated reports of rotation in the clouds. The warnings were concentrated
in central and south central Ohio. Overall slow storm movement also led to some
localized flooding in central Ohio.
