MD80 super 80 flight crew distraction by WX fail to reset altimeters to 29 pt 92. The result is 400 ft overshoot on the climb. The autoplt had disconnected further adding to the confusion. The overshoot caused a TCASII alert on another aircraft.

Narrative:
During climb with first officer flying in the middle of thunderstorms, we became overloaded and failed to level off at FL200. Just prior to leveloff (the 7TH altitude assigned) the autoplt disconnected. I was distraction by a TCASII TA and by WX returns on the radar. I discovered later that I had failed to reset my altimeter to 29.92 at FL180. The net result was an altitude overshoot of approximately 400 ft. This is a perfect example of how multiple distrs, coupled with pilot error (failure to set altimeter and to make the 1000 ft below call) and a mechanical malfunction (autoplt), can lead to noncompliance. Supplemental information from acn 367240: at that time center called traffic at 11 O'clock and FL210. I reported the traffic in sight then immediately received a TCASII TA at FL195.

Title: MD80 SUPER 80 FLC DISTR BY WX FAIL TO RESET ALTIMETERS TO 29 PT 92. THE RESULT IS 400 FT OVERSHOOT ON THE CLB. THE AUTOPLT HAD DISCONNECTED FURTHER ADDING TO THE CONFUSION. THE OVERSHOOT CAUSED A TCASII ALERT ON ANOTHER ACFT.
Narrative: DURING CLB WITH FO FLYING IN THE MIDDLE OF TSTMS, WE BECAME OVERLOADED AND FAILED TO LEVEL OFF AT FL200. JUST PRIOR TO LEVELOFF (THE 7TH ALT ASSIGNED) THE AUTOPLT DISCONNECTED. I WAS DISTR BY A TCASII TA AND BY WX RETURNS ON THE RADAR. I DISCOVERED LATER THAT I HAD FAILED TO RESET MY ALTIMETER TO 29.92 AT FL180. THE NET RESULT WAS AN ALT OVERSHOOT OF APPROX 400 FT. THIS IS A PERFECT EXAMPLE OF HOW MULTIPLE DISTRS, COUPLED WITH PLT ERROR (FAILURE TO SET ALTIMETER AND TO MAKE THE 1000 FT BELOW CALL) AND A MECHANICAL MALFUNCTION (AUTOPLT), CAN LEAD TO NONCOMPLIANCE. SUPPLEMENTAL INFO FROM ACN 367240: AT THAT TIME CTR CALLED TFC AT 11 O'CLOCK AND FL210. I RPTED THE TFC IN SIGHT THEN IMMEDIATELY RECEIVED A TCASII TA AT FL195.
