// Interpretation

VFR — ceiling 11,000 ft. Light winds at 360°/6 kt, gusting 19, visibility better than 10 statute miles, scattered at 4,600 ft, scattered at 6,500 ft, and broken at 11,000 ft. Reported weather: light rain (-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. 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.
