// Interpretation

MVFR — visibility 3.7 SM. Brisk winds at 150°/16 kt, gusting 27, visibility 3.7 SM, scattered at 1,600 ft, broken at 4,500 ft, and overcast at 8,000 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.
