// Interpretation

IFR conditions — visibility 2.5 SM. Light winds at 040°/4 kt, visibility 2.5 SM, a few at 1,600 ft, a few at 2,300 ft, and broken at 8,300 ft. Reported weather: thunderstorm with rain (TSRA). Would deteriorate to LIFR below 500 ft ceiling or 1 SM, or improve to MVFR above 1,000 ft and 3 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.
