I guess, "was due to come home" or "hadn't yet come home" would be another way to put it.
"Youse", "youinz", and "yinz" are mostly a Western PA/Pittsburgh thing, and seldom heard where I live. But, there's quite a bit of different dialects across PA. If I meet someone with a particular dialect I recognize, I can tell within a minute or two which surrounding county they grew up in, and in at least one instance, which particular town. I've met people before and have said, "Oh, you're from Shamokin!" When they ask how I know that, I tell them, "It's how you pronounce your "o's". (They pronounce it lower and more gutteral.) I'm personally fluent in Pennsylvania hick, and have been pegged myself as being from PA when I've been out of state, just by my manner of speech. And don't get me going on speech in other parts of the country. We have family in the South and we both laugh at how we speak and phrase things.
