Could someone explain why Windy shows different amounts of clouds on different views? For example, in the forecast for tomorrow, the airgram shows no clouds, while the map indicates an almost 100% cloudy day.

@vicb It's great! Thanks.

Nice. We will see how it work. Some ideas:

• calculate speed of lifting
• rating soaring condition
• better sounding, like eg. xcmeteo.net.
