I am impressed by the weather forecasts by Windy.
This time, however, there is a striking difference which I cannot explain:
we are in Les Menuires, France, which is 1800m high. The site location forecast says that air temperature is -10 to -14 degrees, but is only -1 to -3 according to standard measurements.
A difference of 10 degrees (in all weather models) during the last 7 days is too much as to be caused by local variations.
Is there anybody who can explain?
