What is wrong with my rabbit?

I live in New Jersey and it has been getting very cold lately outside so I bring my pet rabbit in from her outdoor cage and place her in a small one in my basement. I have done this before with no problems. But she has been down there for 3 days since it has been really cold and windy lately. But today when I checked her, her left ear was flopped over (which I have never seen both are always up) and her right eye was bulging. It also appears that her nose is all stuffed up because she sneezed and then made a snorting sound. Anyone have any ideas? I know i need to take her to the vet but its 8:30pm and we are suppose to get 10 inches of snow over night and so the vet might not even be open tomorrow.
