Narrative:

En route, encountered unforecasted WX and inadvertently entered IMC conditions. Was able to climb to 2500 ft MSL and get VFR over top. I was able to contact approach, update WX and request radar vectors for an ASR approach. Unable to get an ASR approach and requested radar vectors to VFR conditions. Given a heading of 020 degrees and was able to break out into VFR conditions 20 mi south of the field. What caused the problem was the reduction of lighted surface references once I had left the city area. There are a lot of black hole areas out there in the rural areas that are dangerous. Got to always be one step ahead of the game and have several contingency plans available and ready to execute.
