Stationary fronts prolong bad weather

A cold front is the boundary between cool and warm air when the cool air is replacing the warm air. A warm front is the boundary when the warm air is winning the battle. When the pushing is a standoff, the boundary is known as a stationary front. Stationary fronts often bring several days of cloudy, wet weather that can last a week or more.

Since neither the warm air nor the cold air are advancing, the stationary front weather map symbols combine both the cold front and the warm front symbols.

Maps show stationary fronts with alternating triangles pointing away from the cold air and half circles pointing away from the warm air. Color maps alternate the cold front blue and warm front red.

A weather map's frontal position shows where the boundary touches the Earth. The boundary can be thousands of feet above the ground a couple of hundred miles away from the surface front.

If there's enough humidity in the air, clouds and precipitation will form as warm air overruns cool air along a stationary front.

Sometimes, stationary fronts can stay stationary or nearly so for days. When this happens, the sky can stay gray with rain or snow. Stationary fronts are also good places for new low pressure areas to begin and grow into storms.
