Took off from TPA from Runway 19R on the ENDED Nine DP. There was a small TS cell south of the field and the Tower was calling approximately 20 kts. loss of airspeed on the climb from Runway 19L. Runway 19R looked clear to us so we didn't [think] much of it. As we were cleared to takeoff from Runway 19R; we used reduced thrust and Flaps 1. On the climb; we entered IMC and turbulent conditions as we penetrated the cell. I suddenly noticed that the vls was starting to climb up and overtake my airspeed; the vsi had a downward trend and suddenly changed to amber and the 'DON'T SINK' aural warning was triggered. I immediately pushed the thrust levers to TOGA and said 'TOGA Thrust; stow speed brakes' and executed the Windshear (WS) escape maneuver. We continued the maneuver to approximately 5;000 ft. and the Captain reported to Departure that the ENDED Nine DP is not feasible due to the presence of that TS. After 5;000 ft. MSL; we turned on course to the north en route back to ZZZ.
A320 First Officer reported windshear during take off climb resulting in execution of windshear escape maneuver.
