It was calm to perhaps 7 knots from the north-west at the field. The surprise was on rollout, there is a pretty severe ditch filled in with loose rock. The runway goes over a road that links houses on the far side of the runway and that's pretty rough too. Stay to the right if landing to the north. I have been in mountain waves and I agree, they can be tough. We had planes coming from north, south and west and I think everyone had a similar experience. My route from the south was probably the worst weather-wise as I was just below the cloud bases in Raleigh at 5000 and then just above them as I had to climb over the Blue Ridge. Coming home, there was a solid overcast from 6 to 7 thousand that I spent some time in and then noticed the temperature was -5C. Oops. Climbed to 9000 and and it was smooth air and a beautiful (I keep saying that word) ride. The overcast held all the way back to Raleigh, but it had warmed up by then, so no concerns going through the clouds on approach.
