Atlanta got upgraded to a Winter Storm Warning (noting the strong wind gusts). I think Chattanooga is going to get upgraded to a winter weather advisory - if mostly for the NE part of the county being more likely to see snow.

These HRRRs keep giving Chattanooga just a little more snow. GFS is consistent with a dusting here.
Both of those agree pretty heavily on NE TN snow coming in high.
Both have lower piedmont Carolinas snow totals than ECMWF/GFS guidance.
Curious how the 12z ECMWF looks.

I still lean towards noting to a dusting for Chattanooga.
ECMWF has given us a little snow in the forecast now, but at least as of this afternoon it was the only one.
Although be aware that anything that falls will stick, which is my biggest watch out. Between 2am and 8am.

The crows are out on the ice in the shallow marshland grass, looking for food. Not usually a place they can check, but in this weather, it's possible. Smart bird

Up to 5200 without power now. Must still be all ice on the mountains. Looks like Sequatchie county added quite a few outages on the back side of Signal.
Winds are reportedly picking up around town.

Beautiful graph showing RH, Temp, Dew Pt from the local mesonet.
Precip starts and RH spikes, and temp drops because of evaporative cooling. Moisture content goes up slowly and then temps rise very slowly with more relatively warm precip falling.

Another crude illustration. The cold air has filled in the bowl. The return flow is trying to push northwest but has to clear the bowl to not create more ZR.
That's a mixing process need. Typically turbulence or precipitation

QPF baby!
Here's a storm aspect I haven't looked at enough: QPF.
Chattanooga is expecting 2.5in of precip equivalent: Whew...I knew it was a lot but that's sooo much water especially for temps to drop into the teens Sunday night.
