Weather Summary and Icon

[dshanske]

I'm trying to figure out how to match weather APIs like Weather Underground, OWM, etc in terms of one missing feature. Has anyone ever implemented a way to generate a text summary and icon representing current weather conditions and if so, what logic did they use?

Considering that most of these are things like sunny, cloudy, rainy....etc. I have a rain gauge, so if it is raining, I assume I could say that. I don't even know how you measure cloudiness. And I can tell night or day mathematically.

I thought someone might have given this some thought, otherwise, might be an interesting discussion.
