Narrative:

On ILS approach to the runway and with thunderstorms in the area we intercepted the localizer and began our descent out of 3;000 ft. Just as we began our descent approach said the RVR was dropping rapidly; and quickly came back with an RVR well below the minimums for the approach and added that there were windshear warnings of -20 KTS in the landing area. We decided to go around from our present position (approximately 2;700 ft) and I disconnected the autopilot and hit the toga switch.the aircraft pitched up for a 2;000 FPM climb with the commensurate throttle change and trim setting and we rapidly climbed through the missed approach altitude of 3;000 ft. The captain and I both noticed the excursion as it was happening; confirmed 3;000 ft as the desired altitude; and I retarded the throttles; and pitched/trimmed forward. Topping out at approximately 3;500 ft we returned to 3;000 ft after a few seconds; got vectors for another approach and landed on a different runway with better weather conditions. I should have left the autopilots engaged and quickly called for the go around standard actions which would have had us engage VNAV and recovered us to the 3;000 ft missed approach altitude in our MCP altitude window.

Title: A B757-200 pilot executed a go-around at 2;600 FT because of weather and overshot 3;000 FT after employing full power and pitching up.
