Usage

• certainty about the future based on evidence or fact from the present or the speaker's opinion, "If you don't hasten, you are going to get caught by the police and haled back to gaol." "Woeful tidings I bring – the clouds I have seen just behind this mountain, but heading our way, indicate that our humble dwellings are going to be swept away by the impending storm."
