I have OEM rotors and pads, and experience the same problem this past weekend. Drove on the highway for 5 hours in rain and 40 degrees. I just had to remind myself that every few minutes I needed to give my brakes a tap.
I think it is the cold water constantly running over the pads and rotors. Kind of like putting a beer in cold water cools it down faster than putting it in a freezer.

I have a similar issue, but it is mainly just wet conditions. Any time I'm driving in a good rain, my braking can be delayed, kinda like you have experienced, Keith. Its because your rotors and pads get damp. I make sure to periodically dry/warm mine when its raining by applying the brakes lightly with my left foot. I do this regularly in the rain. I've had some of those pucker moments due to wet brakes.

i've experienced this with stock pads. i was always taught to tap the breaks light in wet weather anyways to make sure you're stuffs ready. first time it happened it did take me by surprise as i was in traffic ... aka my butthole did pucker.

I had this happen to me too in the rain. Scary at first because I was going fast. I guess I need to "dry my brakes" more often!

As discussed, this happens to me with the stock pads. I do practically all highway driving, so I've figured it out, but the pucker always happens.
I've heard that newer bmws put the pad closer to the rotor when wet to keep them from cooling too much. That hasn't been verified but I've never heard of this issue with stock e90s.
First time I ever experienced this was on my e30 with upgraded pads/rotors in the rain.

So doesn't that mean faster brake wear?
