Hello, I am using Windy a lot for my flying and loving it. One addition that would be useful is to have the dew point relative to the temperature (at different level) instead of absolute. Indeed, the closer the dew point is to the temp, the higher the probability of a low visibility. Just a suggestion. Thanks for the good work guys
On "sounding forecast"
you can see the temperature/dew point spread at different levels.
e.g. at 21,000 ft the spread is 3 degrees.
P.S. flight visibility is also afected by fine particles (dust, sea salt) in the atmosphere. So, you may have low visibility even in low humidity (dry haze)
especialy if you fly eastwards early in the morning (towards sunrise).
