Weather
I was the first officer and we were going between two thunderstorm cells with the radar on. We then entered some clouds and got severe turbulance and the airspeed was depleting quickly so I took over the controls and started to descend to prevent a stall the captain told me to put the autopilot back on after losing a thousand feet and then he had the controls. After the airplane climbed 1;000 feet in just a few seconds it started having at least 50 kt windshears and the autopilot kicked off. The captain took the controls and tried to keep the speed he then got more windshear and got the stall shaker. At that point we did a stall recovery and told ATC we needed FL350 and they gave it to us. We then could put the autopilot back on and proceed with moderate turbulence.With the unexpected turbulence I can't think of what we could have done much better.
While flying in the vicinity of thunderstorms; CRJ-700 crew encountered severe turbulence and windshear resulting in altitude deviations and stall warning activation.
