Witnesses reported acft descending in vertical spiral and then impacting gnd vertically. Wx rprts and forecasts indicated thunderstorms, turbulence, and lightning were present along flight. Two plt rprts indicated presence of moderate to severe turbulance in vicinity of the accident site, within 1,000 ft of acft cruise alt. Review of pilot's logbook indicated he was not ifr-current.
