Warm Front Warm fronts often bring stormy weather as the warm air mass at the surface rises above the cool air mass, making clouds and storms. Warm fronts move more slowly than cold fronts because it is more difficult for the warm air to push the cold, dense air across the Earth’s surface.
Q. What direction do storms move?
This segment of weather 101 focuses on storm motion and why we generally see storms move from west to east. The easiest answer is the jet stream. In the United States, the wind above our head tends to move in a direction from west to east. These act to steer our storms and move them across the country.

Occluded fronts
Q. What is the occluded front symbol?
Symbolically, an occluded front is represented by a solid line with alternating triangles and circles pointing the direction the front is moving. On colored weather maps, an occluded front is drawn with a solid purple line.
Q. What do weather front lines mean?
Known as the colorful lines that move across weather maps, weather fronts are boundaries that separate air masses of different air temperatures and moisture content (humidity). It is the literal front, or leading edge, of air that’s moving into a region.
Q. What are two conditions you need for air mass formation?
What conditions are necessary for an air mass to form? It must stay over a land or sea surface long enough to acquire the temp/humidity/stability characteristics of the surface below. They are associated with source regions, they must be extensive, physically uniform, and have stationary air.
Q. How is a warm front shown on a map?
On a weather map, a warm front is usually drawn using a solid red line with half circles pointing in the direction of the cold air that will be replaced. Warm fronts usually move from southwest to northeast. A warm front can initially bring some rain, followed by clear skies and warm temperatures.
