// Interpretation

VFR — ceiling 3,400 ft. Moderate winds at 060°/12 kt, visibility 8.0 SM, scattered at 1,700 ft, broken at 3,400 ft, and overcast at 4,800 ft. Reported weather: -RA. 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.
