An air carrier B757 overshot its assigned altitude in climb. TRACON departure controller technique ATC. The controller apparently did not notice the reporter's high rate of climb. Aircraft performance very high rate of climb at low and medium altitudes. WX factors thunderstorms in the area that required deviation complicating the controller's work. Departure controller workload probably very high.

Narrative:
Location: s-se of ord. Departing ord in thunderstorm conditions. Departure cleared us to FL190. While deviating due to thunderstorm departure amended altitude to 13000 ft. We were at 12800 ft, 3000 FPM climb aircraft stopped at 13500 ft while on its way back to 13000 ft.

Title: AN ACR B757 OVERSHOT ITS ASSIGNED ALT IN CLB. TRACON DEP CTLR TECHNIQUE ATC. THE CTLR APPARENTLY DID NOT NOTICE THE RPTR'S HIGH RATE OF CLB. ACFT PERFORMANCE VERY HIGH RATE OF CLB AT LOW AND MEDIUM ALTS. WX FACTORS TSTMS IN THE AREA THAT REQUIRED DEV COMPLICATING THE CTLR'S WORK. DEP CTLR WORKLOAD PROBABLY VERY HIGH.
Narrative: LOCATION: S-SE OF ORD. DEPARTING ORD IN TSTM CONDITIONS. DEP CLRED US TO FL190. WHILE DEVIATING DUE TO TSTM DEP AMENDED ALT TO 13000 FT. WE WERE AT 12800 FT, 3000 FPM CLB ACFT STOPPED AT 13500 FT WHILE ON ITS WAY BACK TO 13000 FT.
