Weather Tidbits: Dryline

The dryline is explored in this Weather Tidbits. A dryline is a boundary of sharp moisture or humidity change. They commonly occur over the southern Plains. A dryline happens when three air masses, a low pressure and cold front are involved. The 3 air masses are the continental polar (cold and dry air) behind a cold front, while ahead of the front, there is the continental tropical (hot and dry) and maritime tropical (warm and humid). Areas along the dryline will see storms that could be severe; as the dry and hot air collide with the slightly cooler and humid air ahead.
