I recall some doozies. Wish I had the totals from GFW.

I don't recall that much snow growing up in central, either. It certainly was colder, though.

Definitely plausible. The heaviest will be in the farthest southeast and east.

Lol, I didn't live in St. John's in 2001 hahaha.

Here are my thoughts on a timeline for snowfall and winds for St. John's and vicinity.

As noted, there remains uncertainty with regard to this particular system, so forecast confidence is lower than normal.
