Why do tornadoes seem to avoid Chicago?

I live in Chicago, and as you probably know a huge storm system came through the Midwest today and caused significant damage to a few small towns in Illinois. Although I recall tornadoes hitting the outlying suburbs before, I don't remember the last time one actually hit Chicago. A lot of Chicago's weather is strongly affected by Lake Michigan, does it sort of "shield" the city from tornadoes?

While there is some minor justification for believing that urbanization can cause storm-splitting, the more likely scenario is that you are simply paying attention to Chicago, so you notice every time it doesn't get hit.  If you paid close attention to a particular (arbitrary) location on a dart-board, you'd notice it never seems to get hit.  It's just an observation bias.
