Narrative:
Planned south approach into okc. Two severe thunderstorms well north of airport and one well south along a strong cold front. Upon contact with approach control advised [another air carrier] encountered windshear on approach; executed go around and returned to departure airport. Approach also advised wind had shifted to north landing gusting 38 knots and windshear alert of 25 knots. We leveled at 9;000 feet and took delay vectors in clear/smooth ride. Shortly thereafter winds reported 20-25 knots with no windshear alert. We accepted descent and vectors for approach. With configuration flaps 1 speed 210 knots descending on downwind turbulence began to increase to moderate continuous. Airspeed shortly thereafter increased rapidly and I disconnected auto pilot to prevent flap overspeed. It was quickly followed by a rapid severe decreasing performance windshear; severe loss of airspeed and sink. We executed a go around and diverted to ama. After parking brake set we reported in-time per current company guidance and 'stay' on FAA interpretation of flight time. After refuel we returned to okc and flew 7:46 for the day. However with a ground time of 1:18; it could have been 9:04.
