I'm officially in freakout mode for our trip. We are driving to Chicago Friday night, staying at the Clarion on Cicero- 2 miles/10 minutes from Midway. We're parking at the Midway Park Saver across from the terminal entrance. Our flight leaves at 7:40 AM. Current forecast for the weekend is a 30% chance of snow on Friday, 10% chance of snow on Saturday. If you were in my shoes, what time would you aim to be at the airport?
