If you drew a line that continued I-75 from south of the 40 split northeast, that would be about the cut-off as of 2am of where the good stuff begins from what I can tell. RadarScope is pressing the blue line into Loudon, Lenoir City, Oak Ridge and over towards Clinton. I'm in the green but getting a 50/50 rain/snow slop. Temp is slowly dropping, 35.6 on the weather station here with a dew point of 33.8. Nothing sticking here yet. Any hardcore snow junkies still up that can give some ground truth to I-75 guess?
