Narrative:

I had been in contact with flight watch and flight service and was advised that the conditions were still VFR at 4;000 ovc. I continued inbound to land and when I was cleared into the airspace; I entered a few clouds that were obscured against the heavy fog that was coming in. At this time; all of the surrounding airports were also covered up by this same front. I descended down to 1;000 ft MSL to try and exit the cloud layer; which did not work; so I climbed to a safer altitude. While the ATIS was still calling for VFR; the ceiling was actually 900 ovc. I was cleared to land on runway 36 at which time I got into some turbulence when I came out of the clouds to see that the visibility was about two miles. I was not able to see the airport; and was using my GPS as my primary navigation to head towards the airport. I asked tower to turn on the runway lights; at which time I could barely see the threshold lights and the beacon. The landing was normal.

Title: C172 pilot on VFR flight plan inadvertently enters IMC during descent and approach to destination airport. GPS and a request for runway lights aid in locating the airport and a normal landing ensues.
