Narrative:
Over pensacola; fl at FL350; aircraft encountered severe turbulence that lasted 10 seconds [or more]; followed by moderate turbulence. The weather did not show on the radar. LNAV and VNAV disconnected and aircraft jolted upwards approximately 1;300 to 1;400 feet. I turned the auto pilot off; slowed the aircraft down and simultaneously brought the aircraft back to FL350. ATC was advised of encounter and altitude deviation. At the time of the occurrence captain was using the lavatory and returned to the flight deck as soon as he could. There were no injuries during the incident. Aircraft landed safely without any further incidents.
