The witches in macbeth are the first characters who appear on stage. How would you describe the mood that they create

It is dark and stormy and ominous. Something is not right in the Elizabethan universe and the audience is about to be let in on it. Elizabethans really believed that witches were the Devil's servant. They believed they were ugly old and just bad news. So, Shakespeare hits his audience with a triple dose of witch in the first lines of the play, "When shall we three meet again In thunder, lightning, or in rain?". They then go on to call all kinds of badass spirits (animal spirits) to help them out. All the while it is lightning and thunder. So, the mood of the first seen sets us up for the rest of the play. The darkness in the first scene slowly spreads across the entire play making the forbidden and ominous mood and consistent.
