Wintry Feb. 19-20

I mentioned this several days ago in a comment to Burrel2.
The reason I remember this particular storm was bc it was on my wife's birthday.
I bought her tickets for Kid Rock/Buckcherry that day.
A storm similar to a spring shower or thunderstorm came out of no where began to snow at 42° or so and in 45 to an hour.
We had 2.5 - 3 inches in that short timespan.
It was Feb 16 2013.

You could literally get in your car and drive up 29 towards GVL from Greer and within 3-5 miles there was nothing.
What a memorable storm that was.
MBY went from 43 to 32 in about 5 minutes. Had 2” in 45 minutes and it got to me right as it was getting dark so even the roads got quickly covered
 
This system has Upstate SC and North GA in so much confusion.. Do we all get rain? Do we get a brief mix? Do we get a brief burst of snow? Or do we get an all snow and or snow/mix event. A lot to be figured out over the next 30 hours.. These small shifts drastically change things run for run. I'm honestly just completely lost when it comes to forecasting this down here. I'm sure many others are as well.
The only thing that has been consistently good for our area has been the GRAF which performed well for both January events. We’re right on the line it seems
 
Right entrance region of the jet over the mid Atlantic and warm advection aloft definitely points to an amplification/wetter trend once the synoptic pattern finally settles in. Looks like that is starting to happen here.
That would definitely introduce more mixing issues but oh well. Give me a high qpf winter storm any day of the week lol

Seems like a Feb '20, but a bit further north type situation could be the deal in North Georgia and the NW Upstate.

I can also cosign and say that I'd say the GRAF faired fine in Georgia to me at least in January, even if Carolina folks don't agree. It felt like the GRAF and maybe FV3 were the only models suggesting any snow at all with January 10th as far south as it got (the RGEM did well showing the band, but it was wrong on p-type as that death band was snow/sleet).
