Late yesterday afternoon a cold front passed through the area and brought some rain with it along with some nice cool air. As I walked across the wet parking lot to my car after getting off the train I noticed that my car windows were covered in condensation. After I hopped into the vehicle and started the engine I turned on the wipers to clear away the moisture from the windows. The condensation however was inside the car. The warm humid air that was trapped in the car condensed on the windows as the temperature dropped during the afternoon. This is not a major event nor an earth shattering insight, but rather an interesting little science moment, and another indication that fall is well underway -- as if the beautiful foliage and the fact that inside the house is chillier than outside (another micro-climate) were not enough.
