Narrative:

While flying to ZZZ; I was the captain/pilot monitoring. Thunderstorms were in the vicinity of ZZZ and the weather was above ILS minimums. Other airline aircraft were landing with reports of tail winds on approach and light to moderate turbulence with moderate rain. We were #2 on the ILS xxr approach while the aircraft ahead of us landed. At minimums; the rain was heavy and the runway was hard to see; so we went around. We asked ATC for a straight out missed approach to stay out of the heavy weather. We made a left downwind and began setting up for another attempt for runway xxl; since conditions were improving on the field. At that time; we experienced a roll; then loss and gains of altitude. Wind shear followed without any warnings as we performed the escape maneuver. We were unable to maintain altitude; so I asked ATC for higher. Severe turbulence followed and we climbed to 6;000 feet with a vector away from the weather. Once the aircraft was under control; we diverted to ZZZ1 and landed without any incident. No injuries occurred.
