Nah, its an xplane thing, it seems xplane Atis, just uses some random weather report on initial load, after about 15 minutes it refeshes and uses the one in the Metar report, you can test it for yourself, pick a runway with clouds etc, and listen to the metar, it will change, this morning at YSBK its saying weather is clear, but it is actually over cast and raining, after 15 minuets it updates and weather is correct, of course skymax already has clouds displayed as it is reading the correct Metar report.
