Narrative:
Was climbing out of a class B airport on a SID; at approximately 11000 ft while in and out of cumulus clouds we flew out of one and noticed a significant buildup at 12 o'clock; within 2 or 3 miles. Captain (pilot flying) immediately requested that I request a deviation right of course to get away from the buildup. As per [company] profile we were flying at 290 kias in our climb.the cell we were about to enter was borderline imminent given our speed leaving us seconds to make the decision to fly into it or turn. By the time we had initiated the turn we were partially inside the cell experiencing moderate turbulence. Immediately after requesting; approach responded 'negative; contact center on 123.45. Captain initiated the turn as I contacted the next frequency also informing them that we had deviated due to a significant buildup. During the turn I noted that there was no traffic to our right within 10 miles. Center responded normally and thanked us for informing them of the turn. I stated we were back on course and they once again responded normally. Continued for a few minutes until center advised us of a possible pilot deviation and gave us a phone number to call on the ground.
