Narrative:

The event occurred while departing austin executive airport which is located under the class C airspace surrounding austin airport. I departed the airport with what I believed was 1000 ft ceilings and improving conditions. Route of departure was due west. Within 2 mins following liftoff, I found myself descending to avoid the lowering cloud deck. At the same time, the ground in the area was rising slightly. Not feeling comfortable in making a turn, I proceeded forward. I immediately saw what appeared to be a break in the overcast and made a very fast decision to attempt to proceed up through it. The autoplt (wings leveler) was on. I did find myself in IFR conditions for approximately 20 seconds before breaking out on top at approximately 2000 ft AGL. I may have violated the class C airspace. A misunderstanding of information received from a WX briefer 2 hours previously helped contribute to my poor judgement regarding an appropriate takeoff time. Regardless, I still should have been able to assess the situation better.
