B737 flight crew on approach was informed of windshear by ATC and elected to go-around. During the go; severe turbulence was encountered causing flap overspeed and an altitude deviation. The flight crew subsequently diverted to their alternate.

Narrative:
[We were on] short final 19R at mci. Tower reported microburst and preceding flight reported windshear +/- 50 knots. Go-around was initiated quickly followed by a windshear alert in the aircraft. Tower gave me a heading of 090 and altitude of 3000 feet for the missed approach. During the turn and climb; windshear and severe turbulence were encountered. I called for flaps up during the go-around climb and cleanup. Flight instruments were difficult to read and fluctuated from 190 to 250 knots. I noticed flaps were at position 1 during the climbout. Airspeed; altitude; and flight control were difficult to maintain. I heard the captain say we over sped the flaps so I asked him why he didn't raise the flaps to up as requested. He told me because the airspeed was varying so much and we were recovering from the windshear. (It made perfect sense to me). I had some difficulty trying to level off at 3000' and climbed to 3300' momentarily. ATC didn't seem concerned. Preceding aircraft reported windshear and hail just after touchdown. I diverted and landed at stl. Aircraft was grounded for inspection.
