Wind on the ground was 10-15 kts, but 30-40 kts at 1000-2000 ft.
Thats a fair to middling wind-gradient that, potentially 20kts over 1000', if mainly a headwind, necessitating significant a/c acceleration. It was rough and squally nearby all lunchtime, at one time maybe gusts of 30-40 mph at ground level, quite unstable air mass then.
