A "warm front" happens when a warm air mass moves into an area with colder air. Warm fronts usually bring weather that consists of large cloud areas and rain.

During wintertime in the Maritimes, we hear the term Nor'Easter a few times during the season. A Nor'Easter is a north easterly wind that blows along the eastern seaboard. This warm air meets with cold Arctic winds in the Gulf Stream and causes the Maritimes' worst storms. It can bring blizzards, white-outs, and a cold wind chill factor. People from the Maritimes prepare for bad weather when they hear that there is a Nor'Easter in their daily forecast.
