Narrative:
I dispatched an aircraft with a portion of the deicing capabilities MEL'ed. I checked and re-checked the WX that evening and felt it could legally be dispatched. I even noted on the release that the captain should call if uncomfortable, drawing his attention to the MEL and route. While the forecast remained 'clear,' WX conditions at departure time (from clt) for destination (ewn) showed a ceiling. I did not monitor closely the changed sa for ewn and alert the captain. But the flight proceeded normally and landed ewn.
