// Interpretation
MVFR — ceiling 1,000 ft. Light winds at 230°/4 kt, visibility 3.1 SM, overcast at 1,000 ft. Reported weather: mist (BR). Mist is water droplets thinning visibility to between 5/8 and 6 SM — the moist, lighter cousin of fog. 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.
