How far south does the constant winter snow reach?

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.

I live in NYC/Long Island and it's never like that here, the precipitation is mostly rain. During that December Blizzard the snow stayed on the ground for about 3-4 days which was a lot.

Our average high is like 40 degrees and we dip to 27 degrees at night, so it's not like we usually stay below freezing too long.

Let's see, Dec./Jan. pretty much guaranteed, in Feb. you might see patches of lawn if it gets warm enough, just depends on how much snow and the temps.

I was gone all day today, came home and could tell the pile by my driveway is a few inches lower!

I believe climatologists chose the-3C/27F coldest month average isotherm line as the boundary between temperate and subtropical climates because it represents the limit of continuous snow cover.

In the Northeast that would roughly correspond to extreme northern NJ, lower Hudson Valley to central CT to inland suburbs of Boston.

Not in Dayton Wyoming. The mountains above us have snow year round, but down here we have snow, it melts, snows again, all winter long. Snow will seldom stay for over 3 weeks at a time before it's melted.

In my neck of the woods (Dakotas and Minnesota)

of course it varies year to year....but on average my experience living in the area over the past 11 years shows that you can expect continuous snowcover over the winter north of a line from about Williston North Dakota to near Bismarck...then to Aberdeen SD then east to about St Cloud Minnesota

Specifically where I live....in most years your first lasting snow cover starts in mid to late November and then continues until about early April. Snow melt and ice melt starts in the Red River valley in late March in the southern basin and early April in the north on average. You may not know this but the Red River of the North flows northward from its origin near the ND/SD/MN border to Winnipeg then eventually into Hudson Bay. This is a big reason we have spring floods as it melts first in the southern basin and water flows north into the area where ice cover still exists. Also the area is very flat allowing the water to spread out easily.

Snow that falls in November will be here til April ( central Minnesota)

Many posters who live by the ocean ( Vancouver and NYC) benefit from the ocean in regards to snow not lasting.

I'd like to find a map of that boundary.

True, the ocean tempers the temp.

In Toronto, we have piles of snow lasting about 90-95% of the winter,
but as far as true snow depth like out in an untouched field,
we probably have snow cover lasting maybe 60% of all winter days.
Seeing snow is definitely more common than not seeing snow.

Continuous snow cover, every winter?
Probably have to go at least as far north as North Bay, Ontario.
