On a somewhat related note, XP real world weather seems to be off as of recently. I had it showing storms at LFPG last night when there was none reported in the area, as well as overcast from -541ft (!?) with ceilings @ 10,000ft at KMSP when METAR stated visibility was 10sm and broken clouds @ 8,000ft.
