The Ubimet weather forecast for the day is in, and it predicts a much better day than we've seen – in fact it looks like a classic flying day in the Alps, with light wind and cumulus clouds building in the afternoon: "Saturday will start mostly sunny with only a few low-level clouds along the northern slopes of the Alps in Switzerland. Until noon it will stay dry everywhere.
"Around noon, some cumulus clouds will form over the Alps. The tendency for local showers will increase in the subsequent hours. First showers are expected to fall at 14:00 local time. Isolated thunderstorms are also possible. However, these are not severe and once built they will move slowly towards northeast."
