Narrative:

While being vectored for a visual approach to runway 24, traffic departing mht was called out as 12 O'clock, 1 mi, same altitude, also under control by mht departure control. Aircraft appeared from haze and overcast on collision course when 500-1000' away. Strong evasive maneuvers by both aircraft avoided collision. Had WX been solid IMC this would have been a midair. ATC should have provided vectoring to maintain separation. Again, both aircraft were under positive control by mht departure.
