It's about 50/50...
Last year, we had beautiful weather up until early Jan...(by beautiful, I mean no really *huge* snowstorms

..well, maybe one or two, but nothing awful. I think school was cancelled two days through Nov and December)
Just lots of overcast days, some flurries, mixed with rain, sleet kind of stuff.
All that being said, even if there is stormy weather, road crews around here are awesome, and the main roads are well kept. If you have decent snow tires on your car, and drive defensively, you'll be fine
And we'll have to meet at Tim's for tea!!
Have a wonderful trip!!!
Thanks. Tea sounds lovely! Where is Tim's?
We are from just outside Washington DC, I posted about moving up to the Cape recently - we are not comfortable living between DC and a nuclear powerplant anymore and want to start a little sustainable farm in beautiful NS. We were going to fly up but, its going to be like $1200 US. We have family in Boston so, we will make a pit stop there and plow on up to NS the next day. It is a 17 hour trip. We could drive the other direction and be at WDW in a 17 hours, ironically!
Thanks everyone for responding. It sounds like the odds are good that we should be fine in the 2 WD Volvo Wagon in early December. Kicking myself now for not springing for the 4WD Volvo XC! Our vehicle does have good tires and it has a bad weather mode for the transmission and it has very responsive handling.
