// Interpretation

MVFR — visibility 5.0 SM. Light winds at 010°/7 kt, visibility 5.0 SM, scattered at 1,800 ft. Reported weather: haze (HZ). Haze is fine dust, salt, or pollution particles suspended in dry air — it reduces visibility and washes out contrast, a dry particulate obscuration rather than a moisture one. Note that automated stations can't chemically tell smoke from haze — during a regional smoke event, this may in fact be drifting wildfire smoke reported as haze. 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.
