Some rain could be on the way for your Thanksgiving holiday, but it won't be enough to get us out of our extreme drought. This morning, the water level at Lake Thurmond is about 12 feet below normal for the winter, and we're still in the fall. North of Atlanta, Lake Lanier is at its lowest level ever at 18 feet below normal. That lake is Atlanta's main water supply, and rain there is 20 inches below normal this year.
