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.
SR20 pilot reported departing with the assumption weather would remain the same as the arrival; but ice accumulated unexpectedly during climb.
