Hi, let us help / give advices the best way... what you expect to get from using Weather Underground API ecosystem?
As a user, from my point of view, I can see WUAPI as a repository of weather datas, nothing more, since every user is supposed to supply his/her code.
Have you experiencing troubles using a particular feature, difficulty in builing location query or issues in unexpected data for particular API url? If so, let us know what URLs you're working on_ Remember that it is always possibile for the current WUAPI version to "debug" your calls via a regular internet browser.
Instead if you're facing core programming difficulties or similar, I believe is outside the purpose of this forum, focused into WUAPI usage topics so worth seeking out for answers elsewhere like stackoverflow or something similar.
