Yeah, it can be fairly interesting, .....tough to predict, though: it doesn't actually take too much precipitation in the air for flash to fill up the air with reflections. A few snowflakes really close to the lens can kind of dominate the frame, really, so it's best to try to get under an overhang to shoot from, (or back up against a wall that's blocking any breeze,) if you can, even if your subject isn't.
I've kinda wondered about the wireless possibilities, have someone take such a flash way off-axis to see if it looks a little more 'real.'
I think WR flash is one of those things that, well, hey, they probably may as well design them that way next time, if it doesn't get in the way of anything else, but I never needed it before, and plastic bags still work fine for anything special.
(Come to think of it, I wonder how many of the high-tech features of modern flashes wouldn't be thrown off by a fair amount of precipitation, anyway, scattering the signals or just making the automation react to the rain and not what you'd rather. Something old and manual might do just as well for all that. )
