Narrative:

We noticed a flash of lightning north of our track. Using the WX radar we were only able to paint light to medium precipitation north of track but nothing along our track. Looking ahead visually we saw nothing but clear sky and stars above, but there was no moon yet and it was very dark. The dispatcher said in an ACARS message just mins before that all the rides ahead had been reported smooth. All of a sudden the overspd EICAS and aural warnings went off and the captain immediately retarded the throttles and turned off the automatic throttles and autoplt. He told me to turn on the seatbelt sign and the ignition switches to continuous. He was battling very hard as we immediately started climbing at about 3000 FPM. I then told the flight attendants over the PA to take their seats immediately. We encountered st elmo's fire but no discharges. The captain finally got control of the aircraft as we were approaching FL370, and then eased it back down to FL350. The turbulence we encountered was moderate to severe as for a few moments we were unable to control the aircraft. During the steep climb I made a transmission to any other aircraft that might be along our track, but fortunately we were ahead of the pack that night. We talked to the flight attendants right away and it was a mess in the cabin but nobody was hurt except 1 flight attendant who felt like she may have aggravated a previous back injury. No passenger were even out of their seats so that was good. No other flts behind us encountered anything other than a little light to moderate chop. We notified commercial radio immediately and had them pass everything along to dispatch, who talked with us eventually on a phone patch. We made a logbook entry and after a cabin inspection and group discussion we deemed the aircraft able to continue on to our destination.

Title: B752 ENCOUNTERS MODERATE TO SEVERE TURB DURING CRUISE FLT EBOUND FROM LIH IN A NIGHT OP.

Narrative: WE NOTICED A FLASH OF LIGHTNING N OF OUR TRACK. USING THE WX RADAR WE WERE ONLY ABLE TO PAINT LIGHT TO MEDIUM PRECIPITATION N OF TRACK BUT NOTHING ALONG OUR TRACK. LOOKING AHEAD VISUALLY WE SAW NOTHING BUT CLR SKY AND STARS ABOVE, BUT THERE WAS NO MOON YET AND IT WAS VERY DARK. THE DISPATCHER SAID IN AN ACARS MESSAGE JUST MINS BEFORE THAT ALL THE RIDES AHEAD HAD BEEN RPTED SMOOTH. ALL OF A SUDDEN THE OVERSPD EICAS AND AURAL WARNINGS WENT OFF AND THE CAPT IMMEDIATELY RETARDED THE THROTTLES AND TURNED OFF THE AUTO THROTTLES AND AUTOPLT. HE TOLD ME TO TURN ON THE SEATBELT SIGN AND THE IGNITION SWITCHES TO CONTINUOUS. HE WAS BATTLING VERY HARD AS WE IMMEDIATELY STARTED CLBING AT ABOUT 3000 FPM. I THEN TOLD THE FLT ATTENDANTS OVER THE PA TO TAKE THEIR SEATS IMMEDIATELY. WE ENCOUNTERED ST ELMO'S FIRE BUT NO DISCHARGES. THE CAPT FINALLY GOT CTL OF THE ACFT AS WE WERE APCHING FL370, AND THEN EASED IT BACK DOWN TO FL350. THE TURB WE ENCOUNTERED WAS MODERATE TO SEVERE AS FOR A FEW MOMENTS WE WERE UNABLE TO CTL THE ACFT. DURING THE STEEP CLB I MADE A XMISSION TO ANY OTHER ACFT THAT MIGHT BE ALONG OUR TRACK, BUT FORTUNATELY WE WERE AHEAD OF THE PACK THAT NIGHT. WE TALKED TO THE FLT ATTENDANTS RIGHT AWAY AND IT WAS A MESS IN THE CABIN BUT NOBODY WAS HURT EXCEPT 1 FLT ATTENDANT WHO FELT LIKE SHE MAY HAVE AGGRAVATED A PREVIOUS BACK INJURY. NO PAX WERE EVEN OUT OF THEIR SEATS SO THAT WAS GOOD. NO OTHER FLTS BEHIND US ENCOUNTERED ANYTHING OTHER THAN A LITTLE LIGHT TO MODERATE CHOP. WE NOTIFIED COMMERCIAL RADIO IMMEDIATELY AND HAD THEM PASS EVERYTHING ALONG TO DISPATCH, WHO TALKED WITH US EVENTUALLY ON A PHONE PATCH. WE MADE A LOGBOOK ENTRY AND AFTER A CABIN INSPECTION AND GROUP DISCUSSION WE DEEMED THE ACFT ABLE TO CONTINUE ON TO OUR DEST.
