If you scroll down on to the bottom of Apple Weather it has a “Report an Issue” button which allows you to report current weather conditions at your location.
I have no idea what happens to that data and if it contributes to the report in any way.
Wow I would have assumed that was to report a bug not a weather call. Darksky had a great ui for quickly reporting the weather and encouraged it as the primary feature of the app.
