// Interpretation

MVFR — ceiling 2,500 ft. Moderate winds at 030°/10 kt, gusting 25, visibility better than 10 statute miles, scattered at 2,000 ft, broken at 2,500 ft, and overcast at 3,400 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.
