Some uncertainty still remains as to exactly where Hurricane Sandy is headed, but it seems more and more likely that this will become a major storm event for the northeastern U.S.
On the current forecast track, the low pressure center of Sandy (or its remnants) should come onshore sometime in the Tuesday/Wednesday time frame of next week. The specifics of who will see what is still a couple of days away, but now is the time for people in the New England and the Mid-Atlantic states to begin preparing. The strong winds and rain could begin as early as Sunday for the Mid-Atlantic; with those effects spreading farther north with time. As the storm approaches land early next week, tropical storm conditions (winds of 39-73 mph) appear likely for much of the northeastern U.S. coastline. Stronger wind gusts are certainly possible. 
Heavy rains can be expected along with those breezy winds. This should lead to numerous power outages for some of the country's most populous cities. Farther inland, the wind will be less significant, although tropical storm force wind gusts can still be expected.
What makes this storm particularly interesting is that it will merge with a cold front currently advancing through the Midwest. As the cold, arctic air is pulled into the western side of Sandy, abundant tropical moisture brought by the storm should begin to convert over to snow for areas well inland. As the snow accumulates on trees and other surfaces in these areas, the breezy winds may also be enough to bring down trees and power lines.
Closer to home, the impacts will be far less severe. For the Georgia-Florida game, wind will be the main issue. During the game, sustained winds of 25 mph can be expected with gusts of 30-35 mph. Rain chances will be fairly low. It's still possible that an outer rain band or two will work through the area, especially early in the game. Any rain could be heavy, but the downpour shouldn't last for too long.
In Middle Georgia, I suspect that all will see is a bit more cloud cover than in recent days, as well as occasional wind gusts around 25 mph.
