Though I don't know jack about programming/design, here's one I imagine won't be too hard to pull off but would up immersion substantially with weather. Switch the sound of rain when I step indoors to the sound of rain on the roof rather than the constant "natural" sounding rain we get now.
Probably harder to pull off but would help immersion even more, make the area darken. Put dark clouds in the sky when it rains. Make it so I can see the rain a little better. It usually feels like it is thundering but I barely see the rain and the sky is bright.
