Antoine's Forecast

Saturday, June 20

Machine translation Read Antoine's original, in French →

Heat dome

High pressure situation. We are under a heat dome. This gives us scorching days. Saturday, the day will be sunny with cumulus in the afternoon. The air mass will be a bit less unstable than Friday, but there is still a risk of seeing storm cells develop.

Wind

The wind is forecast light and from the South-West sector. We're talking 10 to 20 km/h for the 2000-3000 meter layer.

Thermals

Thermals higher than 3000 meters.

Clothing

At 2000 meters between 11 to 23°C Rhône valley between 17 to 34°C (oops!) 0°C isotherm at 4100 meters.

Dangers

The danger will be the thermal conditions (breezes) from the middle of the day with possible overdevelopment. Indeed, it's not enough to look at the forecast ceilings, you'll also need to watch the development of the cumulus. Watch out for gusts ahead of the storm cells. IN FRONT OF THE BIG FLUFFY CLOUDS, THE CAUTIOUS PARAGLIDER PILOT NO LONGER TAKES OFF! (that one's worth a coffee!)
