Next spring (second week of May), I'm looking to explore upstate New York before my sister's graduation from Syracuse - I live in California, and have never been to New York outside the city, so I've been exploring various travel options. Everything I've seen has made Buffalo much more attractive of an option, price-wise, to the point that I think it might well be worth the extra ~hour out of the way (from what I can tell from Google Maps) compared to the Rochester airport, or the Syracuse airport (obviously much more convenient; also crazy expensive from the west coast, plus I'd rather get the excuse to explore more anyway.)
I can handle the extra drive time, but as I've never been to that area, I figured I would ask to make sure, weather-wise, whether that plan would be foolish. My mom, who has visited my sister there before, says when she was there in mid-April, there was still snow everywhere. So I suppose my two questions would be:
If I were thinking of driving from Buffalo to Letchworth National Park, then to Syracuse by way of passing through Watkins Glen, then back to Buffalo (obviously not in a day - I'd have over a week for this trip), how likely is it that I would encounter weather hazards (i.e. snow) in early May?
If the answer to #1 isn't "highly unlikely", and I were in a budget rental car, how well maintained would those roads be / how well equipped would a budget rental be to handle said hazards?
