Weather Forecast: Balloons should turn in 12hours

The green line represents what would happen if you flew at 10,000 feet. The blue is for flights at 5,000' and the red for flights at 2,000. The stars are 6 hours apart. So staying low would mean pilots follow the red line to the centre of France, and staying high leaves the balloons in the Mediterranean sea after 24 hours
