Do April showers bring June brides? Storm also could mean to abruptly enter or leave. A tempest can be the maelstrom, or as in the play, it could be the agent of change...a stormy period, as the young lady went through puberty. A thunderhead could be the clouds of an approaching thunderstorm, or refer to an act at the peak of a drama that suddenly changes the story's direction. You can clearly see it in the foreshadowing, but its far off at present. I was just commenting on the I-Ching in another post. It wet my appetite; as the rain fell, ink started to run in rivulets.
