What does the term "overcast" signify in weather reports?

The term "overcast" in weather reports signifies that the sky is completely covered with clouds. This typically means that the cloud cover is extensive and can impact visibility and overall weather conditions. Specifically, in meteorological terms, "overcast" usually indicates that the cloud base is below a certain altitude, often around 6,500 feet, which can lead to reduced sunlight and potentially different weather phenomena, such as precipitation.

This distinction is important for pilots and meteorologists as it affects flight operations, visibility conditions, and various weather-related decisions. Understanding the implications of "overcast" helps in anticipating weather changes, managing flight paths, and ensuring safety in aviation.
