Narrative:
I was flying south near the parks highway and as I proceeded, the ceiling and visibility deteriorated gradually to where I turned back north and flew approximately 5 mi north when I was unable to continue north because the ceiling and visibility were down to zero! This was due to snow and clouds. So I turned back south and continued south along the highway. As I traveled south, the road was winding and I crossed it a few times and on 2 occasions, I was within 600-800 ft of a vehicle. After about 10 more mi south, the ceiling and visibility went back to approximately 5000 ft overcast with 50 mi. There was nothing I could have done. The WX closed in behind me!
