Narrative:

I was flying home after an evening of flying in beautiful WX. A severe storm came up and I tried to make it home. I got as far as a neighboring airport and their lights would not come on. It was becoming quite turbulent as the storm got closer. I had to turn and run. I was skirting rochester class C trying to read my sectional for frequencys. The plane is equipped with red light only (it's a rental). It was impossible to read the map in the lighting and the by now severe turbulence. The tower had been watching me and began signaling me with the light gun to come on in. I had been flying with full lights so I acknowledged his gun by blinking my landing lights and came on in. I taxied to the FBO and called the tower. He told me I'd done great and everything was fine. I'm filing because the plane owner advised it.
