Comment

Spring thermal flight over the foothills. Both Topmeteo and Skysight predicted better thermals over the plains but the inversion lingered persistently there. Small cu popped up over the foothills so that's where I went. Lift was weak (5kt max) and inconsistent. Cloud bases between 9.5k and 11.5k. A convergence zone was all the way back over the mountains. I could see the higher cloud bases under the convergence at around 15k but made no attempt to reach it (seemed hazardous to me). Tried to get some distance but my speed was quite slow as I tried to stay close to the clouds requiring frequent attempts to center weak lift. Fun flight in pleasant temperature and good practice.
