It can snow as early as October and as late as May. Or it can not snow at all. There's really not a set pattern.

Snow tires are better than all season tires but it depends on whether you're going to be driving much on unplowed roads during the storm. If you have the ability to limit driving during the active storm and immediate aftermath, snow tires might be overkill.

Salting a driveway is a waste. Having icemelt is good if you don't clear it completely and it freezes over or something.
