I will intentionally ride in moderate rain showers. Warm summer showers can actually be quite pleasant to ride in. If I know I'm going to get wet, I just put the fenders on the touring bike (also my gravel/winter bike) and go for it.

Over the years I have also been caught in some far more significant weather events including hail, high winds and torrential rain on several occasions. The only times I've bailed for cover have been when there is lots of lightning close by or hail bigger than marble size. I wouldn't intentionally set out to ride in severe weather, but it makes for good stories when a storm pops up out of nowhere and catches you on open road or in the middle of a gravel grinder out in the boonies.
