What is back door cold front?

A back door cold front is a type of cold front that enters an area from the east or northeast, rather than from the northwest or west as a typical cold front would. The term "back door" refers to the fact that the front enters the area through the "back door" rather than the expected or usual location.

Back door cold fronts are most common in areas on the east coast of the United States, particularly in the summer months. They can bring cooler temperatures, lower humidity levels, and increased cloud cover to the area they pass through.

Back door cold fronts can also produce precipitation, particularly in the form of light rain or drizzle due to the relatively cooler, moisture-laden air they bring with them, which can produce clouds and potentially some precipitation.

Overall, back door cold fronts can have a range of effects on weather conditions and can be a somewhat unpredictable weather phenomenon.
