Narrative:

I was on a flight to ZZZ. As I neared ZZZ; I got the WX and heard that it was foggy and had a layer of clouds at 100 ft AGL. I couldn't believe this to be true because I had a visual on the runway; and had the REIL rabbit in sight. I leveled off at 1500 ft MSL; tpa; when I inadvertently flew into a cloud. I immediately transitioned to the instruments and made a gradual descent where I broke out at 1100 ft MSL. It appeared that the cloud layer was sloping down to the mid-field of the runway. I followed the PAPI lights down to the runway and landed VFR. I believe the problem arose because it was so dark out that I could not see the cloud layer. I corrected the situation by descending. If I could do the event over; I would have just diverted back to ZZZ1 where it was VFR and had a ceiling of 5500 ft AGL.

Title: AN INSTRUMENT RATED C150 PLT FLYING VFR ENTERED IMC CONDITIONS LNDG AT ZZZ.

Narrative: I WAS ON A FLT TO ZZZ. AS I NEARED ZZZ; I GOT THE WX AND HEARD THAT IT WAS FOGGY AND HAD A LAYER OF CLOUDS AT 100 FT AGL. I COULDN'T BELIEVE THIS TO BE TRUE BECAUSE I HAD A VISUAL ON THE RWY; AND HAD THE REIL RABBIT IN SIGHT. I LEVELED OFF AT 1500 FT MSL; TPA; WHEN I INADVERTENTLY FLEW INTO A CLOUD. I IMMEDIATELY TRANSITIONED TO THE INSTRUMENTS AND MADE A GRADUAL DSCNT WHERE I BROKE OUT AT 1100 FT MSL. IT APPEARED THAT THE CLOUD LAYER WAS SLOPING DOWN TO THE MID-FIELD OF THE RWY. I FOLLOWED THE PAPI LIGHTS DOWN TO THE RWY AND LANDED VFR. I BELIEVE THE PROB AROSE BECAUSE IT WAS SO DARK OUT THAT I COULD NOT SEE THE CLOUD LAYER. I CORRECTED THE SIT BY DSNDING. IF I COULD DO THE EVENT OVER; I WOULD HAVE JUST DIVERTED BACK TO ZZZ1 WHERE IT WAS VFR AND HAD A CEILING OF 5500 FT AGL.
