Narrative:

Takeoff runway 25, with planned left turn at 7 DME on SID. When airborne, departure control gave straight ahead heading with right turn at approximately 7 DME. We were climbing to FL070. There were thunderstorms to the north and I had the radar on looking for a hole to penetrate. The captain also was looking at the radar, and was in a climbing right turn to a heading of 360 degrees and FL070. We both acknowledged the standard 1000 ft below call. The right turn and thunderstorms all came together and we both missed the leveloff at FL070. The altitude alert system went off at 7300 ft and by the time the captain reacted, 7500 ft was reached. The captain pushed the nose over and quickly recaptured FL070. We had a TA on TCASII. Departure control asked if we were leveling at FL070 and I said yes. Departure control did not query us after that. We continued on a northerly heading avoiding the thunderstorms and level at FL070 with no further incident. The problem was the common 'two heads down and fixating on a problem' and did not continue to fly the aircraft.

Title: THE FLC OF A WDB ACR WERE ATTEMPTING TO AVOID TSTMS AND OVERSHOT THEIR LEVELOFF AT 7000 FT ASSIGNED.

Narrative: TKOF RWY 25, WITH PLANNED L TURN AT 7 DME ON SID. WHEN AIRBORNE, DEP CTL GAVE STRAIGHT AHEAD HDG WITH R TURN AT APPROX 7 DME. WE WERE CLBING TO FL070. THERE WERE TSTMS TO THE N AND I HAD THE RADAR ON LOOKING FOR A HOLE TO PENETRATE. THE CAPT ALSO WAS LOOKING AT THE RADAR, AND WAS IN A CLBING R TURN TO A HDG OF 360 DEGS AND FL070. WE BOTH ACKNOWLEDGED THE STANDARD 1000 FT BELOW CALL. THE R TURN AND TSTMS ALL CAME TOGETHER AND WE BOTH MISSED THE LEVELOFF AT FL070. THE ALT ALERT SYS WENT OFF AT 7300 FT AND BY THE TIME THE CAPT REACTED, 7500 FT WAS REACHED. THE CAPT PUSHED THE NOSE OVER AND QUICKLY RECAPTURED FL070. WE HAD A TA ON TCASII. DEP CTL ASKED IF WE WERE LEVELING AT FL070 AND I SAID YES. DEP CTL DID NOT QUERY US AFTER THAT. WE CONTINUED ON A NORTHERLY HDG AVOIDING THE TSTMS AND LEVEL AT FL070 WITH NO FURTHER INCIDENT. THE PROB WAS THE COMMON 'TWO HEADS DOWN AND FIXATING ON A PROB' AND DID NOT CONTINUE TO FLY THE ACFT.
