The typical progression of clouds with an approaching warm front starts with high-altitude, thin cirrus clouds. As the front gets closer, these are followed by cirrostratus, then altostratus, and finally nimbostratus clouds, which can bring prolonged precipitation. This sequence reflects the increasing moisture and decreasing altitude of the cloud bases as the warm front approaches.
