How to put more EMOTION into this scene?

How to put emotion into a scene? By SHOWING what's going on, rather than telling it. You can do it in little ways - physical gestures that characters make and by drawing parallels to what is going on around them. Many highly emotional scenes in literature are set in the middle of storms - for the very good reason that storms themselves are highly charged, and bring with them the expectation of catclysmic happenings.
