What does "OVC" represent in a weather report?

The term "OVC" in a weather report is an abbreviation for "Overcast." This indicates that the sky is completely covered by clouds, with no clear gaps. An overcast condition typically implies low visibility and can have implications for flight operations, as pilots need to prepare for potentially reduced visibility and instrument flight rules. The other options do not accurately represent what "OVC" stands for in meteorological terms. For instance, "Overwind" and "Overhead clouds" do not have established meanings in weather reporting, while "Observation condition" is more general and does not specifically convey the relevant information about cloud cover. Therefore, identifying "OVC" as meaning "Overcast" is important for interpreting weather data correctly, especially in fields like aviation where safe navigation and decision-making depend on accurate weather assessments.
