  1. Each time period answers the question: "If I go at <XX>, what is the weather that I should expect?". So, approximately:
    • AM - from 4am till noon
    • PM - from noon till 8pm
    • night - from 8pm till 4am next day
  2. Wind arrow shows direction of air flow. So arrow pointing up means wind from south to north; arrow pointing right means wind from west to east.
