On AMD documentation web site: For raining effect you can read this file (http://developer.amd.com/media/gpu_assets/GDC06-Advanced_D3D_Tutorial_Day-Tatarchuk-Rain.pdf) .For sky rendering you can read this file (http://developer.amd.com/assets/D3DTutorial_Crytek.pdf).These two files are on this web page (http://developer.amd.com/documentation/presentations/Pages/default.aspx).
On NVidia (http://developer.nvidia.com/page/documentation.html) documentation web site: This file for rain (http://developer.download.nvidia.com/whitepapers/2007/SDK10/RainSDKWhitePaper.pdf).Check this web page for nature scene (http://developer.nvidia.com/object/nature_scene.html) with source code. For snow accumulation look at this file (http://developer.download.nvidia.com/SDK/9.5/Samples/DEMOS/Direct3D9/src/SnowAccumulation/Docs/SnowAccumulation.pdf).
Remember that the kinds of effects you want to implements are not trivial especially for rain and for snow. The link of the papers I give you should indicate an approximation of the amount of work necessary to implements these.Finally, some of these papers contain references to other papers so google around for more info.
