Narrative:

We were on a trip to florida. [I] had done [a] more intensive weather briefing before leaving. At fuel stop [in] georgia; did another weather briefing and filed an additional flight plan for the remainder of the trip. Weather briefing was quite detailed and a change of routing was done with helpful suggestion of weather briefer going to a southeastern flight instead of direct south. For the whole trip south we were able to dodge any major buildups until approximately central florida. We were advised deviations were ok left and right 20 degrees. Ran into an embedded severe rainstorm with a momentary loss of control due to turbulence (hardest ever encountered in many hours of flying). As soon as control returned ATC gave new clearance and remainder of flight was normal.
