Narrative:

A standard fuel policy load was used for the flight. WX forecast did not require altitude. Forecast showed frontal passage before our arrival. While en route WX at okc became convective with thunderstorms. On the descent into okc ATC reported no aircraft getting into okc and severe windshear. We were talking to dispatch and elected to divert to dfw. We declared minimum fuel condition and landed in dfw without incident. After refueling in dfw we proceeded to okc with much better WX.
