Narrative:

I was on a VFR flight departing for southern california airport with a central valley fuel stop. I self briefed for the weather on duat. I believed I would encounter a band of clouds in the vicinity of hollister airport (cvh) and that the weather would be clear south of these clouds. I stopped at rhv for supplies and fuel and flew southeast. Above hollister there was a band of towering cumulus. I was climbing and maneuvering to avoid the clouds gradually turning east. At one point; I determined that the path ahead was blocked and that I would not be able to out climb the clouds ahead of me. I initiated a 180 degree; but too late. I found myself in a cloud immediately. I had neglected to note a reciprocal heading before taking the turn. My only alternative (I thought at that time) was to proceed on the planned course; which would take me over the central valley and away from the hills. I had an operating hand-held GPS on board and a zaon pcas device. I continued to climb but could not get beyond 7;500 ft. The aircraft descended to 6;700 ft and would climb no further. My passenger saw the ground through a break in the clouds and I recognized flat land in the vicinity of panoche VOR. Previously I had contacted oakland flight watch to determine the weather at paso robles (prb) and bfl. Both were reporting overcast at 2;500 ft. I know that if I could get under the overcast; we'd be able to land. We descended in the break in the clouds. At 4;000 ft a quarter inch of ice sloughed off the windshield. Under the overcast we proceeded to land at a central valley airport as planned. Writing this now I am amazed that I did not turn back to hollister since I had GPS on board. At least I knew that area to be clear. In many years of flying; this is the first time VFR into IMC (I have 2 hours of IFR training with an instructor in actual IMC; this certainly saved our lives). There are many lessons in this event; things to think about. I need to get much better at interpreting weather between airports; specifically as it relates to ceilings. It is just in writing out the experience now that I realized that I could have turned back; this never even occurred to me until now.
