This would rewrite the record books for late February cold here. Only event that comes remotely close is 1962 and of course 2019. 1962 is the best match though. Those years never saw consecutive days with highs below zero either. Incredible stuff.
In terms of snowfall this event looks to compare to 2019 best. With that said, another 2-3ft of snow on already a 3ft snow base would be unheard of for here.
