Narrative:
Briefly encountered severe turbulence at FL340 in cruise and IMC. Auto pilot disengaged and aircraft rapidly gained over 2;000 ft. Brief airspeed overspeed of about 15 kts. I manually took over the aircraft and returned to FL340 while the first officer (first officer) notified ATC and gave the severe turbulence PIREP. I made the P/a to immediately be seated while returning to FL340. The turbulence only lasted a few seconds. I checked with the lead F/a; and he said everyone was O.K. I then notified dispatch and maintenance and made an entry in the aml (aircraft maintenance log). Maintenance met us at the gate for the inspection. I assume no damage was found because the aircraft left a short time later. There were thunderstorms in the area; but the only heavy convective area on the radar was at about our 2 o'clock and 35-40 nm. A bit of green was a few miles to our left. We had just determined that our course ahead should be fine. ATC had just mentioned the same thing.
