VFR — ceiling 21,000 ft. Brisk winds at 240°/19 kt, gusting 27, visibility better than 10 statute miles, a few at 8,000 ft, scattered at 12,000 ft, scattered at 17,000 ft, and broken at 21,000 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.
