Hey mate
You might want to try Active Sky X as it get all the info from real world weather into FSX. the program downloads weather from satellite and then you choose your Airport code such as PHDH in active sky:)
I use REX 2.0 and Its just amazing
For 100% realistic results every time
Just something to think about. I live near Birmingham so wont be able to come meet you guys
anyway hope everything goes well.
