Check you are editing the correct keyframe on the currently active sequence. In order see your edits as you procede, ensure the time is correctly set in the timeline and that the simulation is running.

Double check you have trueSKY Translucent as a Post Process.
Rotate the SceneCapture2D actor to face downwards.
On the trueSKY Sequence Actor, assign the SceneCapture2D actor to the Rain Mask SceneCapture property. Now precipitation will only appear where there is no cover above the SceneCapture actor.
