// Interpretation

MVFR — ceiling 1,500 ft. Brisk winds at 270°/18 kt, visibility better than 10 statute miles, broken at 1,500 ft, broken at 13,000 ft, and overcast at 30,000 ft. Reported weather: showers in the vicinity (VCSH). 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. Severity rating assumes a standard altimeter setting (29.92" Hg / 1013 hPa); a non-standard setting shifts the effective altitude by roughly 1,000 ft per 1" Hg of deviation.
