You may prefer a more common syntax for the singleton access method,
like getInstance for example.
Personally I would prefer an EventDispatcher rather than the Observer
pattern, creating events like onWindChange, onRainChange, etc..., and a
WeatherEvent object carrying the new weather values.
It'll be more flexible if you want to add more weather phenomenon at a
later time.
My two euro cents.
