Question about weather API calls in KLWP

What are the API query parameters and responses associated with getting weather information?

I use Yahoo Weather for KLWP weather, which is generally the best for me except for wind speed, which is dramatically higher in KLWP than in the app of the same weather provider.

After asking here about the wind speed I heard that KLWP simply reports the results of the API call. I then contacted Yahoo Weather about the issue, and they were not familiar with it. They requested the information in the question above in their response.

(As an aside, KLWP does have 3 other weather providers, but they are generally less accurate than Yahoo for my locations. Particularly for temperatures, which I use much more than wind speed.)
