Narrative:

I was the captain on a B-1900 doing my preflight WX planning for a passenger flight from boston to hyannis, ma. The current and forecast WX is usually printed up on a flight release for every flight. However, this particular time, computer printer problems caused part of the release to be misprinted and unreadable. The portion that was misprinted was the WX and airport conditions for hya. I had called my dispatcher for a current forecast. Having given them the option to either send a new release or read me the WX so I could put it on my release, they verbally told me the hya forecast. The forecast was above landing minimums for hya for about 1 hour after ETA. After checking the current WX and NOTAMS for hya, the flight departed. About 1/2 way through the flight, the crew found current hya ATIS WX had gone below landing minimums. The crew had relayed this information to company operations and then requested ATC clearance back to bos. The flight landed in bos without event. 2 days later the chief pilot notified the captain that, according to dispatch, he (I) allegedly took off with hya current and forecast WX below landing minimums and will seek actions against the captain.
