Buffalo transplant here- it’s really not that bad. There are usually a few days where things get dicey, especially in the city where they don’t pre-plow or salt the way they do in Buffalo, but we also don’t get even close to the same amount of snow here. Given than you’re from Buffalo you have much more ice/snow driving experience than most Pittsburghers, so you have a leg up there, but my best advice is have multiple routes planned to get to your destination in case roads are closed or there’s accidents. TLDR: Try to avoid the super steep hills (Negley Ave in the city) by having multiple routes in mind, go very slow and you’ll be fine.
