Interesting Experience in Chicago Already

Well my wife and I got to Chicago yesterday and what a way to arrive.  We were driving along I-55 when we got caught in this torrential rain.  Now normally rain hitting your windshield at 60 mph makes things pretty tough to see but we were sitting still and I could hardly see.  My wife comments on the trees to my daughter noticing that they are bending drastically.  Then it hit me that I am not in New Jersey anymore and I should be more alert.  The rain slacks up real quick just in time for us to see a tornado forming and making its way to the ground.  It kept forming up to a point and then would kinda lose its form then it would point down again.  We could see the clouds swirling but luckily it never touched down.  My wife had just called her parents and asked if they had any alerts and they said no.  Right when we saw it they called back telling us the sirens were going off.  Well I can honestly say you don't see than everyday and would be okay if I never saw it again.
