What Is Warm Front?
The leading edge of advancing warm air replacing colder air, often bringing steady rain, then warmer, muggier weather. In technical terms: A frontal zone where warm air replaces cold air, with a shallow slope typically 1:100 to 1:300; overrunning warm air yields a sequence of cirrus, altostratus, and nimbostratus ahead of the surface front; drawn as a red line with semicircles.
