@Marco-Ghersi Hi, thank you for the suggestions. We'll see what can be done. For now, the probability of precipitation can be inferred by comparing forecasts from different numerical models.
I'm not sure what your specific purpose is for needing the enthalpy of moist air, but perhaps the wet-bulb temperature might be useful to you. Windy does display that. While these two quantities are not identical, they are closely related — a higher wet-bulb temperature also means higher enthalpy (although the relationship is not linear). Have a nice day, Jari
