The Mistletoe Inn

When they are looking out of the window of the hotel in NYC, it is snowing. A few minutes later as they are walking through the streets, there are green leaves on the trees as the walk under them. The trees wouldn't have leaves on them in December and, being Christmas time, they also would likely be decorated with lights.

Looking out the window at the Chrysler Building, it is snowing. Moments later out in the streets, it is not snowing and there is no evidence that it had been.
