Today finally a very good day with fantastic thermal soaring conditions throughout the day. The last two days have been a bit too windy or overdeveloped giving poor flying on Monday, and making us do something else yesterday (quite a pleasant Gredos Walk). Today a very nice Cu distribution with an easy trip to near the Cherry tree valley pass. On the evening flight the Cus stated to show some uncomfortable vertical development, so maybe increasing instability and humitiy for the next few days!
