Western PA born and bred, and nearly everyone I know from there says ‘laying’.
Youns guys can take that to the bank.
I vaguely recall the expression being used in a poem, but I’ve never heard anyone say it.
In Scotland we ask if it’s lying, rather than laying, and I’ve never heard sticking used…
Laying is all I’ve ever heard in England. Which would suggest lying/laying is a Britishicism and may be some east coast colonial hold over.
OB
In my neighbourhood snow settles, it doesn’t stick. Actually, it does neither any more, as British winters seem to be officially dead. (Although we did have a brief snowfall that settled for a while in late October!). I also hear “laying” though.
For those that claim never to have heard “laying” used with respect to snow, have you never heard the carol Good King Wenceslas?
Good King Wenceslas looked out
On the feast of Stephen
When the snow lay round about
Deep and crisp and even…
Of course, in the carol “lay” appears to be the past tense of the verb “to lie” (if it was from “to lay” then it shold be “laid”), but it could be the reason for the usage…
> Maryland (Baltimore) checking in - we used to say “laying”.
Extended family from Baltimore, myself born there, moved to NJ as a child, back to Baltimore for college ans the next 10 years or so. Family members by marriage from eastern and centerl PA.
Never once heard of “laying snow” until just now.
What snow does in Baltimore is cause everyone to run out and buy every available roll of toilet paper and every carton of milk as though it won’t melt before sunup tomorrow and that is the only way to stave off the apocolypse that is forecast by the weather guy.
Missed the edit window.
Hmm, various reports from Baltimore.
Surely all of us from there know there are various Baltimore dialects. My experience is along the Liberty Rd/Reistertown Road with family and Charles Village/Downtown/Fells Point corridor for myself. That someone else mentioned Towson, yeah, I could see a bit more, err, “proper” “British” sounding dialect from there. Where are the others from? I saw a Columbia, which I would expect to be more neutral. Others?
I also believe El Kabong could be right - he got the “you’n” part that nailed it for central/western PA.
I used to say “settle” in NZ. “It’s snowing outside but it’s not settling.”
Being from Frederick, MD, west of Baltimore, I’ve heard laying, and have probably used it as well. I think times have changed a bit and most people say “is it sticking now”. I try my best to stay away from Baltimore so who knows what those people say. 
Columbia isn’t Balmer, Hon!
What I was going to say.
Yep, Pittsburgh chiming in here. We (family and I) say ‘laying’
Go Steelers!
Yeah, I think it is Western PA that says it. I’m from Altoona, which is technically in Western PA and definitely in the Pittsburgh sphere of influence an’at…
Not that you need another Wisconsin data point, but In SW and Central WI, Snow sticks. Only the weatherman uses the term accumulation.
I’m pretty sure people said “sticking” in southeastern PA. I always thought it was a stupid term. “Stick” to me* meant you could make snowballs. If it got too cold, then it wouldn’t stick any more.
*and I think only to me.
I was born in Towson in 1955 and lived there until 1969. Apparently neither of you ever came over to Linden Avenue when it was snowing.
Although I’m not going to rule out the possibility that my poor overworked old brain just can’t dredge up examples of this usage from my distant past.
I was born in the Mid-West, but moved to Towson in 1969. I wasn’t allowed to cross the street by myself at that point, so I couldn’t have gone to Linden Avenue. 
Over in the Riderwood-Ruxton area, we always said ‘laying.’
Wrong thread.
Of course snow ‘lay’ on the ground. What I was getting at in the OP is the act of the snow not melting on the ground.
West Tennessee (Memphis)–snow “sticks”.
East Tennessee (Chattanooga)–snow “lays”.
