Narrative:

After receiving a clearance from portland; I departed pearson airfield (across columbia river in washington) and planned to fly the columbia gorge going east to hood river. The overcast was reported at 1500 ft; so being at 1000 ft seemed to work. Unfortunately; just a few mi east of pearson; the overcast seemed lower than reported. By the time I entered the troutdale class D airspace; the overcast was such that a 180 degree turn was necessary to stay VFR. I was still on the pearson frequency and had not changed to troutdale frequency and had wandered into their airspace. I was concentrating so much on the lowering overcast that I had not paid attention to the airspace I was transiting. On future flts; I need to pay more attention to the various airspaces along with their corresponding frequencys.
