Chattooga County and the rest of northwest Georgia will get one more dry and unusually warm day today before a much more active stretch of weather arrives Sunday and Monday, followed by a sharp blast of cold air that could bring widespread freezing temperatures by the middle of next week. Forecasters say today will stay sunny, dry, and very mild, with afternoon temperatures climbing well into the 70s and possibly nearing 80 degrees in parts of northwest Georgia. That will make today the warmest and quietest day in the forecast before conditions begin changing quickly.
