// Interpretation

MVFR — visibility 3.1 SM. Winds calm, visibility 3.1 SM, scattered at 1,700 ft, and broken at 20,000 ft. Reported weather: smoke (FU). Smoke aloft is most often wildfire smoke drifting into the area — fine particulates that scatter light and cut visibility even though the air itself stays dry, so it behaves differently from moisture-based mist or 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.
