What is indicated by an overcast layer reported in a METAR?

Clear weather
High visibility conditions
Clouds covering the sky
Winds at 10 knots or less

The correct answer is: Clouds covering the sky

An overcast layer reported in a METAR indicates that clouds are completely covering the sky. The term "overcast" specifically refers to a situation where the cloud cover is at or above a certain thickness, and it effectively means that there is an extensive layer of clouds that obscures the sunlight. This can have significant implications for pilots and drone operators, as it can affect visibility, flight operations, and navigation. Clear weather would imply little to no cloud cover, which contradicts the meaning of overcast. Additionally, while high visibility conditions can sometimes occur with cloud cover, overcast does not guarantee that visibility is high; it may still be restricted due to factors like precipitation or other obstructions. Lastly, winds being at 10 knots or less is unrelated to cloud cover and does not provide insight into the weather conditions inferred by the term "overcast."
