Weather always does funny things, that's why we're always on our toes! Usually, a cold front approaches from the north, northwest, or west, with the wind direction behind the front typically from those directions.
However, back door cold fronts go against the norm. A back door cold front approaches from the east or northeast, with the winds behind the cold front coming from those directions. This typically happens when the clockwise rotation around the high pressure brings cooler air to the south and west, but can develop to the north of a strengthening area of low pressure.
We commonly use the term "back door cold front" when cool, moist air from the Atlantic moves in from the east or northeast and replaces dry, warm air.
