Im sorry but you are mistaken, at least on the December storm. It was wayyyyyy off untill right before the storm started. The NAM and CMC led the way with it. I dont remember much about the January storm though so you might be right there.I may be mistaken but I recall the GFS sniffing out both the December 2017 and January 2018 snow events in Atlanta. Both in the 6 to 7 day range. Ensembles weren’t great but I can’t recall if they saw anything in the long range.
