The diagram below shows what a typical cold front in the Northern Hemisphere middle latitudes looks like. They tend to point toward the southeast
direction, but it can vary significantly such as an east-west orientation or movement toward the northeast if the cold front is wrapping around
the mid-latitude cyclone. A peculiar cold front, known as the back door cold front, approaches from a unique direction. It will tend to move in
a more opposite direction as would be expected compared to a typical cold front. The backdoor cold front can move toward the southwest or
west. An example of a place that can experience back door cold fronts is New England. A synoptic wind flow that produces a wind flow from
the cold North Atlantic Ocean can bring in a back door cold front.
