How is overcast cloud cover described?

Overcast cloud cover is accurately described as full cover of the sky with clouds. This means that there are no breaks in the cloud layer, and the entire sky is obscured. In aviation weather reports, overcast conditions signify that the clouds are covering 100% of the sky, which can significantly affect visibility and flying conditions. Pilots need to be aware of overcast conditions as they may require instrument flying due to reduced visibility and can influence flight planning and safety procedures. Understanding how overcast differs from other cloud classifications, such as broken clouds or partial cloud cover, is essential for interpreting weather reports accurately.
