// Interpretation

MVFR — ceiling 2,000 ft. Brisk winds at 340°/14 kt, gusting 26, visibility better than 10 statute miles, overcast at 2,000 ft. 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.
