Maybe it is that since the air is coming from the NW, and I am at a lower elevation, the air at the surface is able to get here faster than in Dahlonega, since Dahlonega is in the mountains, and on the other side of them as well. Also, 42 is the warmest it is near here. 41 is more common per weather stations.

Sure. Here's the surface wet bulb temps as well.
(For those who are unfamiliar wet bulb temperature is essentially the temperature you'd reach if you saturated the column at your current given temperature and humidity. It's important during winter storms like this when you start (as many of us currently are) w/ temperatures in the 40s w/ very dry air in place. The evaporation/sublimation of precipitation within the column cools the atmosphere, thus raising the relative humidities (& dew points), while the causing surface temperatures to fall closer to freezing, which is exactly what is beginning to happen over North Carolina. Thus wet bulb temperature can give you an idea of how cool the atmosphere can potentially become based on sublimation/evaporational cooling alone, however it doesn't account for cold air and warm air advection which can cause the wet bulb temperature to change by altering the actual temperature irrespective of latent heating.)
You can probably get away with wet bulbs of 34-35F here but that's pushing it. 850s are already solidly below freezing over most of NC, while Columbia, SC has about 2C of work to do but it's definitely doable if the precipitation becomes heavy enough...

The 850's don't seem to be expanding much to the south. I don't think we will see anything

Down to 37.6 here this hour. No precip overhead at the moment either.

NAM finally coming to grips w/ reality and shifts the swath of snow considerably northward in NC on the 0z run, almost into RDU...

The band moving into Memphis looks good

OHHH Webb - too good!
HRRR is a dream for the upstate over toward webber and then NC coast.

what north alabama's chances looking like right now (haven't kept up with this event/thread at all, just happened to take a peak at the radar and became interested)

You will - and if you run out of your favorite beverage, you'll get 10" and all the stores will be closed down -- history does have a way of repeating blows!
The closer you get to TN the better your chances. The band back toward Memphis could drop an inch or so pretty easily but it'll probably be the set of counties bordering Tn. South of that maybe some snow mixed in with the rain or a brief period snow in heavier precip

I remember that one cause I got the shaft. I kept feeling like I was never going to get the big daddy because I had never got more then 6 before last January.
I think you have a pretty legitimate shot the idea of a narrow heavier band looks good. The RGEM upped precip totals again I think I'm in love

This is incredibly frustrating.. I'm in highlands and it's been the sloppiest snow for hours with barely any accumulation. Now, it literally has switched to a rain snow mix..
