Final answer:
In a winter warm front with your back to the cold air mass, you would experience freezing rain. Behind you is the cold air mass, and in front of you is the warm air mass where the rain was liquid before freezing upon contact with the cold surfaces.
Step-by-step explanation:
If you're in a winter warm front with your back to the cold air mass, you would be experiencing freezing rain. Freezing rain occurs when rain falls through a layer of subfreezing temperatures in the lower atmosphere and freezes upon contact with surfaces that are at or below freezing So, behind you, that is, in the direction of the cold air mass, would be the colder temperatures that cause the rain to freeze. In front of you, that is, in the direction of the warm air mass, would be the warmer temperatures where the rain was liquid before freezing upon contact with the cold surfaces. For example, imagine you're standing with your back to a cold air mass, which is moving in from the north. In front of you would be the warm air mass, which is coming from the south. The freezing rain would be falling from the warmer air mass and freezing upon contact with the surfaces behind you, which are at or below freezing.
