Yes NWS has an API with quite a lot of data in XML format. Weather Underground api was supposed to shut off on December 31, but has been extended to Feb 15th of this year. Good riddance, it was very flaky, would return occasional bad data, and all around a bad experience.

From what I understand pretty much all countries have a government run weather service and they all have an API. The problem is they are all different organizations that have different APIs so all the weather api services do is combine every single one of the apis in to one that only requires one api key.

I've found apps that use these global API's are inferior to local apps connecting directly to local API's, the data is a lot more current, more accurate and includes a lot of features like radar images. Not sure if it's an issue with some countries missing a lot of data that mine (Aus) offer or it's missing for some other reason.

Phone OEM's always have to include a crappy global one for some reason.

Well that tends to be the case that generic interfaces to multiple APIs only provide the features that everyone provides.
