So here's the result if anybody looking for a solution in the future, and taking into account the official server won't probably be online forever :
A simple weather data provider for the discontinuated Professional Flight Plan X software. The script fetches raw weather data, METAR and TAF data from the NOAA, US national weather service, which is then compiled to a single file that can be imported in PFPX. More than 15000 reference stations (airports) from PFPX are used and wind/temperature data is provided for each of them. When available, METAR and TAF data is also provided for more than 5000 airports. The original data source is updated 4 times a day, and can provide forecasts for every 3 following hours up to 16 days.
You can download it on the library.
