Narrative:

Location: 125 mi northwest of spp. Entering an area of scattered build-ups I turned on the seat belt sign and made the PA concerning the possibility of turbulence. I then called the flight attendant to inquire at what stage they were in their service. They informed me that the service was complete and all carts were stowed. The 3 of us up front were scanning between the radar and a very dark night sky, with no apparent convective activity within 50 mi. About 15 mins later we spotted a very fast growing build-up off our nose, too close to avoid. The first officer took the aircraft off autoplt and I grabbed the PA microphone to advise the flight attendants to be seated. The turbulence lasted less than 15 seconds. After clearing the WX I called the flight attendants, and they assured me everything was ok. The rest of the flight we were very busy with deviations around WX and monitoring pty WX, with towering cumulus in the area and howard as our only alternate. During this very busy time I overlooked the requirement to report the incident to dispatch. Once on the ground the 3 female flight attendants started complaining of minor injuries due to a liquor cart, which they now said was not stowed and tipped over on a couple of them. The other one claimed a lady exiting the lavatory fell on her.
