What type of cloud coverage does "OVC" represent?

The abbreviation "OVC" in a METAR or TAF report stands for "overcast." This means that the sky is completely covered by cloud, with a cloud ceiling typically at or below a certain altitude. Overcast conditions indicate that there are no breaks in the clouds, resulting in limited visibility of the sky. This is significant for pilots and meteorologists as it affects flying conditions, visibility, and overall weather assessments.

In contrast, clear skies would be indicated by a term like "CLR" or "SKC," and "few clouds" would refer to instances where a small amount of clouds is present but does not significantly obstruct the sky. "Partly cloudy" implies that the sky is partly covered with clouds but still has considerable clear areas. These conditions are distinct from "overcast" and do not signify complete cloud coverage. Therefore, "OVC" specifically denotes that the sky is entirely clouded over, making overcast the accurate interpretation.
