Human Factors
After departure we were cleared to 11;000 feet. Departure advised us of heavy precipitation ahead and said deviations left or right are authorized. We looked at the radar and Captain decided to go west. We notified departure that we are deviating to the west. Departure came back and asked if we were planning to fly west around the storm and said the weather was better to the east. We discussed this and after looking at the radar again we requested a turn to the East. We were instructed to turn left to a 080 heading. We turned left to 080 and continued the climb. We were handed off to Center and checked on with heading and climbing to 11;000 feet. After reaching 11;000 feet; Center said that we were supposed to stop at 10;000 feet. I said I thought we were cleared to 11;000 feet. They responded to remain at 11;000 feet. Shortly after that; we were cleared to our final altitude of 13;000 feet. We must have missed the altitude change during the change from west to east weather deviation. I believe the cause was being distracted by the weather in the area we missed setting up the altitude change on the autopilot. To prevent this in the future; I must focus on fully understanding ATC clearance and if necessary write it down in busy or distracting situations.
