// Interpretation

VFR — ceiling 23,000 ft. Light winds at 340°/3 kt, visibility 9.0 SM, a few at 6,000 ft, scattered at 8,000 ft, scattered at 15,000 ft, and overcast at 23,000 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.
