// Interpretation

VFR with winds calm. Visibility better than 10 statute miles and a few at 3,000 ft, a few at 12,000 ft, and scattered at 24,000 ft. Would shift to MVFR if the ceiling drops to 3,000 ft or visibility below 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.
