Narrative:

Checked recorded WX before flight, scattered clouds 4500 ft, scattered higher (forecast for improving conditions). Flight from hfy to dcy, short stopover, return to hfy. Left dcy approximately PM30Z, altitude 3500 ft. South of oom, clouds lowered, requested landing at bloomington. Approach approved, decreased altitude to 2500 ft. Clouds continued to lower, requested instrument approach. Advised to contact terre haute approach. Visibility dropped dramatically in rain and/or cloud entry. Immediately turned to 270 degrees to lighter sky and away from class D airspace. Broke into VFR almost immediately. Turned to 360 degrees, good visibility. Continued north until past cloud/rain. Requested transition of class D -- granted. Canceled instrument approach request. Transitioned class D and proceeded hfy in VFR. Pilot should have rechked WX at dcy and requested IFR clearance at first sign of lowering ceilings.
