I was Pilot Monitoring and the Captain was Pilot Flying. We were cleared for a visual approach. Winds were reported calm. Below 1;000 ft. we started to lose airspeed and the Captain responded that he was adding power and did so. Within a couple seconds we got a wind shear warning. The Captain applied max thrust and followed the flight director. I called out trends that we were descending. The wind shear warning went away after several seconds. I forgot to tell the Captain 'clear of wind shear' and he asked me 'are we clear of wind shear?'. I responded with 'clear of wind shear'. The approach was then continued; but we were not stabilized since we were slightly high at this point so we floated long in the flare. I said 'we are floating' but did not call go around. We landed and taxied to the gate. After the flight the Captain and I debriefed. We talked about how it all happened quickly but we should have performed a go around in a wind shear situation on approach; not to mention if we are high or unstable for any reason. Wind shear caused this event. Neglecting to call for; and perform a go around led to an unstabilized approach. In a wind shear scenario on approach; a go around should be performed. The Captain and I did discuss how calling for a go around immediately when encountering wind shear can become a threat if the pilot monitoring were to raise the flaps as this should not be done (no configuration changes until clear of wind shear). Nonetheless; wind shear calls for a go around; just no configuration changes until clear of wind shear. Being more clear and direct; saying 'go around' instead of using less direct language like 'we are floating' is necessary. Also knowing your call outs in a wind shear situation is imperative; including 'clear of wind shear'.
First Officer reported continuing to a landing after receiving a wind shear warning.
