Narrative:

During approach ILS/30L had thunderstorms and rain in the area; but no negative PIREPS or sigmets. Noted 10 KT tailwind on final with tower calling 15 KT quartering headwind. Discussed go-around possibility with first officer; at 500 ft - with runway insight - tower called with 'wind shear alert for runway 30L.' we executed a go-around and were directed to turn 170 degrees and climb to 4;000 ft. During the turn; we saw the aircraft 18 degrees nose up; full go-around power with 0 vsi for approximately 5 seconds at 1;800 ft MSL. The first officer started the 'wind shear chant' with vsi; radio altimeter and airspeed callouts. As we passed through this area; we entered an updraft and the aircraft started to climb quickly. Passing 3;500 ft MSL; the first officer called out 3;000+ vsi and I noted that 'altitude cap' was illuminated on the FMA and the yoke was pushed all the way forward by the autopilot. As we passed 4;000 ft MSL with about 2;000+ vsi; I disconnected the autopilot and exerted more forward force to stop the climb at approximately 4;400 ft MSL and return to assigned altitude. ATC was notified and said 'no problem; no traffic in your area.' we proceeded to a holding pattern and waited for that rain area to clear before completing a successful approach about 40 minutes later.
