FSX Weather Engine

[Marty96]

Hi guys!
I'm wondering if anyone knows of an outstanding weather engine to use with FSX other than REX. I use REX4 textures and would like a 3rd party weather engine that has a decent amount of tweakability, problem for me is that my Flight Sim PC doesn't have a permanent connection to the internet so i cannot use real weather. Any ideas?
Thanks

Active Sky Next is newly released and is supposed to be good, - I think you can pretty much configure it yourself without the internet (though can't be sure). There's a free trial version available so you can't really go wrong.

I read on a forum that it's really good around mountains, with updrafts and downdrafts etc, in addition to all the other tweaks you can do.

I don't use FSX since getting P3D2 but as soon as they release a P3D2 compatible version I'm going to get it, - can't wait!
