The National Weather Service noted that new experimental snowfall maps will be available this year for a number of stations across the US, including several in the Southeast. The new maps will show ranges of potential snowfall as well as probabilities of different amounts. That could provide some very useful additional information to what is already available in snow events.
You can read more about them and see a list of participating stations at https://www.nws.noaa.gov/com/weatherreadynation/news/160712_winter_probabilistic_snow.html.
