What is the author's style in The Optimist's Daughter by Eudora Welty?

The narrator in The Optimist's Daughter is omniscient ("all-knowing"), meaning that the story is told from a third-person point-of-view. The narrator is not a character in the story, and is able to enter the thoughts of several different characters, but shows an obvious bias toward Laurel and other southern characters. The narrator is typical of an omniscient narrator in the telling of events, such as the wake at Judge McKelva's house, at which the narrator passes from room to room, describing the people and conversations along the way. The narrator also reveals the thoughts and feelings of several different characters, but never reveals those of Fay and her family.
