Stationary Front
• 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.
