Rain Parrot has the best weather forecast layout of any Apple Watchkit app. Finally somebody has used appropriately sized fonts! Please include humidity in your Glance and in the summary screen of the main Watch app.
The watch app now has this :)
Humidity and UV index!!! Both would be much appreciated living here in Australia; where it can be dangerous to go outside from 9am due to the high UV warning, and the humidity is at 97%
You can have bad hair day alerts
