Narrative:

Was given initial turnout clearance to avoid thunderstorms and climb to 5000 ft. After several mins we were stairstep climbed to 6000 ft. While still deviating around a shower, my first officer (immediately after altitude warning horn sounded) pointed excitedly to the altitude window, at which point I realized we had overshot 6000 ft by approximately 600-700 ft. We immediately corrected back to 6000 ft. The controller did not sound as though he noticed, and said we'd be given higher altitude very shortly after traffic at 7000 ft was clear. At this point all I can say is that I was tired, and was on the first day of a pm schedule which was 'snuck in' on my normally am line. Also somewhat contributing was the area of thunderstorms which had crept over the field. Closing off departures for approximately 20-30 mins. When departures resumed, we were approximately #15 cleared for takeoff and cleared to deviate. (Stress/fatigue/am- pm schedule).

Title: AN ACR MLG CREW OVERSHOT THEIR ASSIGNED ALT ON CLBOUT IN HVY WX.

Narrative: WAS GIVEN INITIAL TURNOUT CLRNC TO AVOID TSTMS AND CLB TO 5000 FT. AFTER SEVERAL MINS WE WERE STAIRSTEP CLBED TO 6000 FT. WHILE STILL DEVIATING AROUND A SHOWER, MY FO (IMMEDIATELY AFTER ALT WARNING HORN SOUNDED) POINTED EXCITEDLY TO THE ALT WINDOW, AT WHICH POINT I REALIZED WE HAD OVERSHOT 6000 FT BY APPROX 600-700 FT. WE IMMEDIATELY CORRECTED BACK TO 6000 FT. THE CTLR DID NOT SOUND AS THOUGH HE NOTICED, AND SAID WE'D BE GIVEN HIGHER ALT VERY SHORTLY AFTER TFC AT 7000 FT WAS CLR. AT THIS POINT ALL I CAN SAY IS THAT I WAS TIRED, AND WAS ON THE FIRST DAY OF A PM SCHEDULE WHICH WAS 'SNUCK IN' ON MY NORMALLY AM LINE. ALSO SOMEWHAT CONTRIBUTING WAS THE AREA OF TSTMS WHICH HAD CREPT OVER THE FIELD. CLOSING OFF DEPS FOR APPROX 20-30 MINS. WHEN DEPS RESUMED, WE WERE APPROX #15 CLRED FOR TKOF AND CLRED TO DEVIATE. (STRESS/FATIGUE/AM- PM SCHEDULE).
