When you're outside on a cold day, the air in your nose is a lot warmer than the air around you. You know how the bathroom gets steamy when you take a shower? Something similar happens in your nose - water drops come together, or condense. Then the drops mix with your mucus and run out your nose.

It's because your body is producing heat to stay warm in the cold weather, and the mucus tends to release easier due to the warmth being produce more dramatically.

cold weather = heaters turned up. When your heater is going it is pumping out dry air. Which you breath in...and get congested at night and runny during the day.
