What does the contraction FEW indicate when encoded in an observation?

The contraction "FEW" in aviation weather observations indicates that there are a small number of clouds present, specifically between greater than 0/8 (not completely clear) and 2/8 of the sky covered by clouds. In meteorological terms, sky coverage is often measured in eighths, where 0/8 indicates a completely clear sky and 8/8 indicates total cloud cover.

The "FEW" designation suggests that there are enough clouds to be significant for weather interpretation, but not enough to pose a significant impact on flights. Therefore, it perfectly describes a condition where there are noticeable clouds, yet they do not dominate the sky. This understanding is critical for pilots and meteorologists as it aids in evaluating flight safety and weather conditions.

The other options do not accurately reflect the definition of "FEW." They either misrepresent the numerical range or imply more cloud coverage than is indicated by "FEW."
