I'm not terribly concerned, and I live right on the banks of the Salt Creek in the western Chicago 'burbs. The creek level is pretty low currently and has plenty of capacity for run-off. I'm sure there are areas that might experience flooding, but I wouldn't expect any more than a heavy summer storm.

A thaw/freeze cycle also isn't that bad if you've already shoveled what you need to. If you haven't, yeah, it's going to suck when to get around to it.
