// Interpretation

MVFR — visibility 3.7 SM. Moderate winds at 220°/9 kt, visibility 3.7 SM, a few at 3,000 ft, and overcast at 3,800 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.
