The sky out of the train window was unpromising to say the least. But the BBC forecast was spot on and the cloud began RJ break around 11. By 12 it looked quite promising with 3/8 and quite nice cus forming. The wind was spot on W around 10-14mph - a bit different from the NW forecast but better for the hill. It took a while to find a climb - the wind was due to pick up so hanging around was risky - but equally conditions were due to improve - so a trade off. After about 30mins a workable climb without too much drift came through and I braved going over the back (warnings about leeside thermals mean 500ft clearance above the ridge is recommended). Base seemed quite low at 3100ft - Lasham was indicating much higher. The wind was almost SSW which meant my target near Oxford was never going to happen. But I pushed south to keep to the train line.
The flight was notable for a particularly low save just across the M5. I'd thought a thermal was lifting off some ploughed fields just before it but couldn't find the core and so had flown on to land downwind of the motorway. I was just turning in to land when a swift went the other way. Somehow I went up with it - like being in a dust devil. Any lower and I think I would have flown into the adjacent grain store.
Long Marston exclusion zone finally did for me as I tried to push round. I probably should have gone north but I hoped I might yet keep to the original plan. I hit some really big rough cores including with a kite coming up over Evesham but they seemed to vanish very quickly. The sky still looked epic on the train at 5pm - somewhat frustrating. But even though it was a short flight it was worth it to have experienced a low save like that - definitely a first.
