// Interpretation

MVFR — ceiling 1,000 ft. Moderate winds at 180°/9 kt, visibility 5.6 SM, scattered at 500 ft, broken at 1,000 ft, and broken at 2,500 ft. Would drop to IFR below 1,000 ft ceiling or 3 SM visibility, or rise back to VFR above 3,000 ft and 5 SM.

Approximate using ~10% perf loss / 1,000 ft DA for normally aspirated, scaled by powerplant type. Verify with your aircraft's POH for accurate numbers — especially above 5,000 ft DA where these rules of thumb diverge.
