Narrative:

I departed 17TE, VFR, destination M78. My GPS course took me well east of P49. I encountered two sizeable buildups topping out at 10000 ft or better about 2 mi or so apart. Forward visibility was almost limitless with good to excellent ground visibility. I decided to proceed between these 2 cells and without warning my left wing dropped to a 90 degree bank and I was descending to the west and being tossed about like popcorn. During this sudden upset I was in solid IMC, lightning, and rain near the town of sattin highway 77 and the brazos river. I kept making descending turns to the left looking for lighter shaded areas within the cell and unknowingly and unavoidably entered P49 restr airspace. With prayer, skill, and luck I broke out of IMC at approximately 700 ft AGL and headed to tpl to inspect the aircraft for damage and fuel. Upon landing I was informed the FAA and other auths wanted to talk to me. I called and explained briefly what had happened and they advised me that no further action would be taken against me at that time, and someone from a government agency may be in touch.
