Michael Foradas, who snapped this photo of Thursday's violent evening storm from the 60th floor of the AON Center, says hail crashed intensely into the windows just minutes after this photo was taken! With winds unimpeded by frictional drag at such heights, the hail was able to hit with particular force.
An e-mail from another Chicagoan, Bill Kijek, who was caught around 5:30 p.m. in yesterday's storm while walking near Clark and Adams, indicates he saw what he thought was white smoke approaching. It turned out to be the rain and hail shaft (which you see on the time lapse of the storm from one of our WGN Hancock cameras) and the approaching downburst, which ended up generating 60 m.p.h. gusts in the Loop. Bill reports it rained for five minutes at the height of the storm harder than he's ever seen it rain before, and that the winds sound like, as he put it, "...the proverbial freight train, then it was gone." Bill's description is that of a downburst. Thanks to all of our readers and viewers for sharing their extraordinary pictures and accounts with us!
