The few times I have been there for Championships the weather has been cool (jackets required in the early hours and at night), delightfully warm during the day, or pouring rain with horrible thunderstorms!

I haven't encountered snow/ice during Championships, if that's what you meant. Coming from LA you might find it a little chilly, but coming from New England we find the weather is great!

Instead of renting a car, consider finding a hotel near the MARTA (public transportation). Just check the schedules online though. If you're volunteering for a job that has to have you at the Dome early or staying late, it could be a potential problem. And don't forget to register in VIMS now if you want to volunteer at any upcoming event, including Championships!
