I think the title of this thread is misleading. I would say a "newscast" is several minutes long, with news stories, a weather update and maybe some local sports scores.
As for a local show of an hour or more, I think most NPR affiliates have that, although not always in the morning, as the thread's title refers to. Maine Public Radio has "Maine Calling" 11 a.m. to noon, repeated at 7p.m. Vermont Public Radio has "Vermont Edition" 12 to 1 p.m., repeated at 7 p.m. Connecticut Public Radio has two local hour-long shows, with different hosts, at 9 a.m. and 1 p.m., repeated from 8 to 10 p.m.
