I'd prob go F+ at this point, the + being for the legit bitter cold/1" snow depth ground blizzard before Christmas.
Our last snowstorm with cajones was way back in Nov 2018 when we got 12.8". Been paying for that one ever since, as we've only cracked the 6" mark once (6.3") in January 2021. That storm in Nov '18 was awesome though. I'd almost be willing to do another 4-season stretch of mostly sub 6"ers to experience another one like that one.
