warm front
A front along which warm air replaces cold air. If the warm air mass progressively passes over ground previously covered by cold air, the front will be a warm front. As this front passes an observer, the heavy-stratus type of clouds and any existing precipitation will give way to a partial or complete clearing of the skies.
