Narrative:

ATR had an first officer pitot heat deferred. MEL said no flight into visible moisture. We did not fly into moisture. MEL could be read 'no flight into forecast moisture.' there were a few clouds at 8000 ft scattered, but we stayed clear. Forecast might have been for light rain possible at sgf. Crew next day grounded aircraft due to rain. Company investigating if we flew into moisture. Turn over to FAA may happen. I believe no violation happened. We did not fly in moisture. Forecast and ATIS were visibility 10 mi, 12000 ft broken, wind 230 degrees, 4 KTS, runway 20 at sgf. Stl clear 10 mi visibility, winds calm.
