The Weather Channel has compiled a great list of the worst airports in the US for weather delays (along with reasons why they made the list). Here is the list, you can click each one to go to that particular city.
One thing to remember on weather related flight problems, it is often not winter that is disruptive. While snow storms will tend to close an airport for long periods and allow TV stations to show video of stranded travelers, sometimes the summer is worse. Thunderstorms are highly disruptive – they move ground crew inside for fear of lightning and they cause planes to talk long trips around the storms.
