Crestline Soaring Society

Normal summer day, on the cool side for August. Plenty soarable though the cores were narrow and not many thermals were much over 500 FPM. The wind was a little more westerly than usual mid-afternoon and the thermals were drifting quickly. I kept thinking I'd locked onto a core and then on the next circle I'd be getting rolled out at some point. The inversion was pronounced and climbs slowed down between 4500 and 5000 - I rode several promising ones up before even trying to go back to Crestline, and then it took two tries and going back rather low. Pine was pretty turbulent but I was mostly between 5500 and 6200 over there. Above 5000 MSL my vario was reading 200 feet low; I guess we had some higher pressure above the inversion.
