// Interpretation

VFR — ceiling 13,000 ft. Moderate winds at 220°/8 kt, gusting 18, visibility better than 10 statute miles, broken at 13,000 ft, and overcast at 24,000 ft. Would shift to MVFR if the ceiling drops to 3,000 ft or visibility below 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.
