Mack,
That was a great storm at KATL, where there was 4” of sleet, a Tony dream!
Ironically, Jan 1988 was during a solid +NAO. And it wasn’t just a +NAO blip. Practically every day of that winter had a +NAO, including 64 straight days 12/25/87-2/26/88:

I’ve said in the past that a -NAO is overrated for major SE US winter storm chances, including for the Carolinas. If folks would look at the data in this link, they’d realize this. I’m not saying it hurts the chances, but I am saying that it doesn’t help all that much per looking at all major winter storms since 1950. The edge with a -NAO has been only slight at best.
Big Carolina winter storms during a solidly +NAO period:
2/1973, 2/1989, 3/1980, 3/1983, 1/1988, 3/2009, 2/2014, the 2 big snows of 1/2018
There has been a significantly greater correlation of big Carolina snowstorms with +PNA than
-NAO though not near a perfect correlation as that is not the case with any index:

My favorite ATL major snow actually experienced: probably snowjam 1/1982. Favorite ATL sleet: 2/1979. Favorite ATL ZRs: the back to back weekend 1/2000 storms.
SAV major snows experienced: 2/1968 and 2/1973 though I was just a kid and didn’t enjoy them as much as I would today as an adult. Favorite major SAV storm (and possibly favorite anywhere): 1/2018 hands down. This was a combo of .5” ZR and 2” of sleet and snow, the largest liquid equivalent for a winter storm there (0.75”) since 1922! And it was 100% wintry with temps under 32 the entire time.
