Please add dew specific humidity (point spread) map instead of relative humidity
Although the relative humidity is nice, but it would be more useful for forecasting if the specific humidity map is available. Moreover it would be more useful if the specific humidity (less than 3 degree celcius) is shaded.
On Windy in addition to the relative humidity, the Dew point is shown as a layer. See More layers in the right menu.
The Dew point is also available in Meteogram for a location.
In Sounding forecast too
However the dew point spread is not directly shown.
