Richdrag5,
Now that I had my fun, I will cease to be a wise*ss. I was told that in order to see rain, you need to go into your display settings and make sure they are high enough to support rain being displayed. (More than likely, they need to be maxed out)
Aside from thunderstorms, if you want different types of cloud decks / rain, you need to go into advanced weather, which you can do in either Quick Combat or Free Flight.
The second part of your question is that in order to include specific weather in missions, you need to create the weather in free flight, and then exit the sim after loading free flight or quick combat. The weather information will be stored in a specific area of the cfs2.cfg file. Then, you need to open up the mission file, and copy and paste the weather information from the cfs2.cfg file into the mission.
Be aware that this is considered a manual edit of a mission, and should therefore be done only after no other changed to the mission are to be made.
For more details about this, please download and review Cody Coyote's Mission Builder handbook:

The relevant information can be found on page 131, in chapter 14.
P.S. - Shadow Wolf 07 recommends that after the chicken, you rub that joystick with a dried monkey foot.
