Probable cause
The airplane’s encounter with an unanticipated localized region of moderate-to-severe turbulence while in instrument meteorological conditions (IMC) associated with strong upper-level wind shear and convective cells. Contributing to the severity of the outcome was the failure of air traffic control to disseminate a recently reported moderate turbulence pilot weather report, which reduced the flight crew’s situational awareness and opportunity to prepare the cabin for the encounter.
