Rotating Cloud in Bolingbrook Looked like 'Slow Moving Toilet Bowl'

The National Weather Service has recorded winds of 70 mph in Bolingbrook at 5:40 p.m. Monday night. A line of severe thunderstorms passing through the area also had a strong rotation, the NWS reported.

Debbie Peterson Garcia posted this video on the Bolingbrook Patch Facebook page around 8 p.m. of a "funnel trying to form right over (her) house." 

"it was disturbing...wish rotation showed better in this video...it was like a slow moving toilet bowl and a knob in the middle that kept trying to inch down...as soon as I lost view in this video the Bolingbrook sirens sounded and we went to the basement...never seen rotation like that so close...didn't like it!"
