Explain motif of the weather

Many early modern plays make use of the weather in order to cultivate a certain mood for a performance. Macbeth is not exception, and is perhaps one of the plays most famous for its inclusion of weather events in its plot. The play is perpetually dark, full of storms, clouds, and ominous weather that makes characters question their sanity. In this way, the weather helps maintain the play's overall bleak and doomed tone.
