Easy.........not much choice really! But I don't mind it... I love a good snow storm!
Most of the time I just wear a heavy hoodie. My fingers are the only thing I have trouble with getting cold.
When I used to actually work outside for a living, it wasn't uncommon to be on top of a big barn replacing shingles.... matter of fact it always ended up being the coldest or hottest days of the year that we ended up on a roof. I hated that, but did find I tolerated the weather more because I was out in it all the time.
For you guys in the south I can see how it would be harder... no time to acclimate to it.
Be careful walking on the darn stuff... walk flat footed and take your time.
