Hi boofhead, some places where FSX is discussed that might be of help to you:
Virtual Flying - boards.ie
Flight Simulator X Forums - Powered by vBulletin
The AVSIM Forums - Viewing topics in MS FSX Forum
I use Flight Environment X (
Flight Environment X) as a plug-in for FSX which gives very realistic clouds and water effects. They are also working on a weather tool which is coming out shortly. Definitely worth checking out.
