Today the National Weather Service office in Peachtree City GA had an online webinar on winter weather. In it, they mentioned a few websites they have for people to use in decision-making that you might find useful. I don’t know if other NWS offices in the region have similar pages, but you may be able to use them even if you are not in the FFC county warning area.
Decision Support page provides an all-in-one place to access a lot of their products used when making decisions about upcoming significant weather: https://www.weather.gov/ffc/dss
Prototype IDSS Point Forecasts is an experimental page that updates the current hourly graphical weather for a point in a more modern display that is good for six days and can be picked for a point anywhere in the contiguous 48 states: https://www.weather.gov/forecastpoints
RWIS data for Georgia provides road data for the Georgia Road Network from the Georgia Department of Transportation, including road temperatures as well as weather information: https://www.weather.gov/ffc/gdot_rwis.
