I've lived in Saratoga county for almost 20 years (the western, rural part), so here are some thoughts: We get an average of 7 feet of snow per winter. However, we've had wide variations--some years, the storms seems to pass south of Albany, some years, they go north. We generally have a week where the high temp. is 0 and low is -20 degrees. We try to make that our week in WDW, naturally, but can't always time it perfectly. Summer's are nice--it's beautiful farm country--with 90 degree days fairly rare. I make sure the kids have quality snow gear and they love winter sports (if they didn't, they'd be in trouble!). We have an in-ground pool, because it came with the house, but I wouldn't have paid to put one in becaus ethe season is too short--Labor Day and that's it.
I hope that helps you. If you have any specific questions, feel free to pm me. If you have a specific town in mind (I assume you're considering a move), I could tell you more about that area. Things can vary, depending on elevation, since we're at the base of the Adirondacks.
