When will snow melt?

With two snow storms on the horizon, not sure when we'll be able to get the car out. We live on a steep hill that is impossible to navigate without chains. We're close to bus stops, so it's not that big a deal. However, for my shoots in Vancouver it is because buses stop running early over there. I could bus to a shoot but would have to catch a ride back to Portland with an actor, assuming I'm shooting one who lives around here. I scheduled the next shoot for the 27th but it's still uncertain if weather will cooperate.
