Narrative:

Took off from eky at XA05. Penetrated clouds at approximately 1800 ft MSL sbound. While in clouds, accumulated about 1/8 inch of ice on wing. Leveled off at 5000 ft MSL, in between cloud layers. Ice failed to come off. Temperature was 25 degrees F. I decided to return to eky. Once in the clouds on descent, temperature increased to about 30 degrees F and wings continued to accumulate ice to about 1/4 - 1/2 inch. While being vectored, I asked to descend lower to where the cloud bases were reported. At 1100 ft MSL I was just at bases with ground contact. Temperature increased to above freezing and ice broke off. 20 mins before departure, WX forecaster reported freezing levels at 8000 ft in area. I decided to level off at 5000 ft to stay out of icing conditions, but that didn't happen.

Title: A C210 PLT HAS AN ICING ENCOUNTER WITH A SUCCESSFUL RESULT.

Narrative: TOOK OFF FROM EKY AT XA05. PENETRATED CLOUDS AT APPROX 1800 FT MSL SBOUND. WHILE IN CLOUDS, ACCUMULATED ABOUT 1/8 INCH OF ICE ON WING. LEVELED OFF AT 5000 FT MSL, IN BTWN CLOUD LAYERS. ICE FAILED TO COME OFF. TEMP WAS 25 DEGS F. I DECIDED TO RETURN TO EKY. ONCE IN THE CLOUDS ON DSCNT, TEMP INCREASED TO ABOUT 30 DEGS F AND WINGS CONTINUED TO ACCUMULATE ICE TO ABOUT 1/4 - 1/2 INCH. WHILE BEING VECTORED, I ASKED TO DSND LOWER TO WHERE THE CLOUD BASES WERE RPTED. AT 1100 FT MSL I WAS JUST AT BASES WITH GND CONTACT. TEMP INCREASED TO ABOVE FREEZING AND ICE BROKE OFF. 20 MINS BEFORE DEP, WX FORECASTER RPTED FREEZING LEVELS AT 8000 FT IN AREA. I DECIDED TO LEVEL OFF AT 5000 FT TO STAY OUT OF ICING CONDITIONS, BUT THAT DIDN'T HAPPEN.
