Narrative:

I landed just 10 minutes previous to departing. Was on an IFR flight plan. Had scattered clouds with only 500 ft thickness. No issues for ice or anything. I filed plan out at 5000; figuring the conditions were the same. This is even though there was a zulu forecast for the area from surface to 16000 ft. Weather was broken 2;800 and I figured tops were the same around 4000. Flight was great and started encountering clouds around 3;200 and then it closed in to 100% IMC. Was on autopilot and focused on temp and wings/icing. Around 4000 I encountered clear that turned to rime. As I continued to 5000 'assigned IFR'. It built up to around 1/4 inch then requested 7000 as for I could see the breakout. At 5500 I broke out in VFR on top and was clear. I made a pilot report of the conditions and continued on. The ice shed via sublimation along route. Part way through I found hole in clouds and descended VFR below to prevent any more icing conditions. Flight landed safely. Next time will adjust for last minute weather conditions.
