I live in Vancouver, BC and snowfall here in winter is somewhat sporadic. Some winters (like 2008-2009) have a lot of snow (more than 3 feet in total) and other winters like this year have had virtually none. I think whether a place is more north or more south isn't the only reason whether a place has more snow or not.
it is always like that though our weather is mild compared to the rest of canada in winter
Had to find an old Koppen map because new ones use 0C/32F as the boundary but that is way too warm for a consistent snow cover. Even on this map it stretches a bit too close to Buffalo IMO.

I agree about avg daily mean of 0 C being too mild for continuous snow.
Every winter is different in Toronto SOME winters have continuous snow cover, or at least virtually continuous snow cover.
Toronto averages a winter mean of about 23 F or -5 C... more importantly December avg high of 34 F (+1 C), Jan of 28 F (-2 C) and Feb of 30 F (-1 C)
One year I saw snow ankle-deep or deeper from mid-November right to late-March.
You would think that NH would have a fairly consistent snowcover... However, bare patches were everywhere today with the mild temperatures. However, expect a good bit of snowcover between December and April.
I guess a map showing that type of boundary would have to be based on average snowfalls for the given areas.
NOAA has snow cover maps, which I always check (mostly to bug my sister once April gets here) but that is a year to year thing not based on a boundary where snow cover is all the time, every winter.

Basically, it is the flip side of freak cold spells in Florida. Continental climate is very unstable and can change dramatically depending on which direction the wind is blowing. Sometimes very cold air will penetrate as far south as the Gulf coast, other times very warm air will go up all the way to the great lakes (melting most of the snow). There are no guarantees.
When snow stays on the ground all winter here in FL there will be no arguments that a new ice age is in the making. We got some snow this year but it only lasted for minutes in most places.
No - we rarely have snow on the ground here in northeast Tennessee for more than 2 or 3 days with any given snow. Some heavier snows may stay around for about 4 to 5, but this last harsh cold weather outbreak we had, not only did we have snow on the ground for about 10 days, we also broke a record of having high temperatures below 32° for so many days in a row. We had never had so many consecutive days that stayed below freezing. I am glad thats over.. we have since been in the 40s and today it hit 57°! Very little snow remains on the ground. Tomorrows 50s and Sundays heavy rain will take care of whats left.
Also, since someone mentioned Wyoming, -------Chinook winds play into that.
Those winds can cause temps to rise dramatically in winter.
Unfortunately for South Dakota, those Chinook winds only reach the Black Hills of extreme western South Dakota and many days the high temp in Rapid City is 20 degrees warmer than the rest of South Dakota.
I wished those Chinook winds reached central Minnesota.
