// Interpretation

MVFR — ceiling 2,500 ft. Light winds at 100°/1 kt, visibility 6+ SM, a few at 1,000 ft, broken at 2,500 ft, and overcast at 7,000 ft. Reported weather: light rain (-RA). 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.
