Why dont you try using PHPWeather or coding your own interpreter for METAR data you take directly from noaa? NOAA has really detailed, readily available information regarding METAR data on there website. A nice hefty regexp can easily chew through it. Also, it's kinda fun to make the interpreter (I know I enjoyed it). Of course, it all depends on if METAR data is even available for your locale, which judging by your location name, I'm unsure.
EDIT: you might find that the example on the PHPWeather site is broken for most locations. It does work, just not always on that site (I've used it on my machine).
