Check out the Hytop radar:

Here are the thoughts from the NWS office in Huntsville:
“Narrow band of light snow currently entering southern middle tennessee and north central alabama at this time. Based on sfc obs and public reports…snow remains light and there are no issues with roads. Back edge of snow/clouds is expected to be through the huntsville area by 4:00pm. Light snow accumulations of up to 1/2 inch are possible across the tennessee counties…northeast madison…jackson and northern dekalb county — especially in the higher elevations where current temps are around 32F. Stay tuned for more details within the hour…”
I will have the next complete discussion and Weather Xtreme video posted here by 3:30…
