The UBIMET forecast for the day for Turnpoints 11, 12 and 13 says a high pressure system will lead to a sunny day in the French Alps. However, they predict some high cloud that will produce shade. Shade means thermals are less strong, which could mean the flying is slowed down. Temperatures in the valley are expected to rise to 35C, while at 3000m it will be 14C. Winds are forecast by UBIMET to be W/SW gusting to 20-35km/h.
