What kind of PWS do you have that’s getting that temp? Nearly every reporting station in Dekalb co plus locations to your north are warmer, 33-34.

There is way to much wind and mixing to have any cold or warm pockets either. The only minor differences could be caused by elevation, but everyone should generally be in lockstep.
 
Can hear the county road crews and their chainsaws on the road at the top of our subdivision, clearing trees that fell over the road. Light to moderate sleet mixing in with the freezing rain now. Just had a wind gust over 40 mph (estimate).

From what I am reading above it really looks the NAM's sucked balls on predicting where snow would fall...

GSP has 4-5"? CLT has 3"?

The NAM has always had trouble identifying the effects of dynamic cooling in these strong FGEN forcing bands… it doesn’t pick up on it until the event is really close in. This is something the HRRR does a great job of picking up on… even when it’s outside of its best range
 
Awfull quite last 10 mins. Frzng rain now taking over. Loosing the cold cloud tops, see water vapor, so expect freezing drizzle, light rain to take over now. Windchill is 4 in Gboro

Check. Its all sleet still
 
It's 28.2 degrees here and the sleet is now mixing with freezing rain at my location. There is a light accumulation on grassy and exposed surfaces and the driveway and sidewalk is quite crunchy and slippery. I almost fell down walking to the storage shed a few minutes ago to get some five gallon buckets to draw up some water in case the power goes out since we are not on city water at my house. Now it's time to rub that rabbit's foot and cross those fingers and toes and hope there are no power issues although I feel better about that seeing the latest trends.

...Mid-Morning Forecast Update...

.UPDATE...

At the time of this writing, the dry slot is beginning to move
eastward out of the forecast area. Strong winds this morning have
led to instances of trees down and power outages scattered across
far north Georgia. Snow amounts of 2-4 inches have moreover been
reported, primarily in far northeast Georgia for now. The wedge
continues to hold strong with precipitation reinforcing it across
north Georgia and keeping temperatures near freezing. Bands of
moderate rain are moving towards northeast Georgia and will soon
overrun the wedge, and a transition to freezing rain is soon
expected in the northeast quadrant of the forecast area. The
combination of ice accumulation from this freezing rain and wind
gusts from 35-45+ kts in northeast Georgia and parts of the metro
will lead to an increase in downed trees and powerlines across this
area. Remember, please use caution and never drive or attempt to
move fallen powerlines.

As the upper low over central Alabama approaches west Georgia, and
interesting observation to note is that temperatures are quite a bit
in south Alabama than in west Tennessee. This is because this low is
occluded to the point that cold air advection is wrapping around the
southwestern side of the low. This cold advection will lower
temperatures further as the low approaches, leading to the potential
for more snow than initially forecast in portions of west-central
Georgia and into the metro area. The Winter Weather Advisory has
been expanded further south as a result, and snowfall amounts have
been increased to 1 to 1.5 inches in the Atlanta metro area.
