  #Person2#: Unfortunately, yes. It will be clear early Saturday morning but there is a high chance of showers and thunderstorms later in the day. There is a severe thunderstorm warning for some parts of the South.
  #Person1#: That certainly sounds like a dreary Saturday.
  #Person2#: It gets better on Sunday, though. The storm systems move east and the skies will clear up at night. It will still be rather cool, with highs in the low 50s. The West Coast will be experiencing some cool time.
