state of weather APIs

[hmof]

Hi,
I am just trying out SIP and interested in weather integration. I see that weather_adj supports WUnderground and Yahoo.

From what I've read elsewhere, WUnderground is no longer available for free, unless you have an existing API key.

For Yahoo, one of the URLs mentioned in the source refers to a non-existent hostname now:
http://weather.yahooapis.com/forecastrss?w=

and the other one returns the message "<message>geo.placefinder table is no longer supported</message>" when I query it:

https://query.yahooapis.com/v1/public/yq...<woeid>%22

Are there any working alternatives?

Thanks,
H.
