There was a good turn out at briefing for the last day of our 'Summer Soaring Week'. With a warm front approaching the forecast for soaring was not particularly hopeful, though I thought that it would eventually trigger after lunch and provide some weak local soaring, so most decided to rig. However, the front brought with it a sky full of lenticulars formed by front associated 'shear wave' which both enhanced and suppressed the weak 'blue' thermals below depending upon whether they were in or out of phase . Phil S took an early launch in his DG and showed us the way - he eventually logged over 4 hours soaring. Chris L and Bob G took a placed tow to the wave and climbed above the clouds. The rest of us struggled on below until the temperatures rose and Cu started to form. Even so it was far from easy to go anywhere - even Pete R in his DG400 self-launcher could only get as far Bury! Eventually we found that we were still soaring passed 6pm with the wave still influencing, in what had turned out to be a fascinating, if at times somewhat frustrating, day.
