IFR conditions — ceiling 800 ft. Moderate winds at 100°/12 kt, visibility 6+ SM, broken at 800 ft, and overcast at 1,500 ft. Would deteriorate to LIFR below 500 ft ceiling or 1 SM, or improve to MVFR above 1,000 ft and 3 SM.

SUMU · day 13 at 01:00 UTC · wind from 100° at 12 kt · visibility 6+ SM · broken layer at 800 ft · overcast at 1,500 ft · temp 14°C / dewpoint 13°C · altimeter 30.06" Hg

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.
