A snapshot sequence from November:
Starting with warm, rain, leaves on the trees.
A week later, full-on Fall – cool, crisp, almost all the trees are bare.
Five more days and 33 centimeters of snow. (That would be the “Winter” component.)
Five days after that and all the snow is melted away. Welcome to an early Spring.
Haligonians are sometimes seen wandering around with a vaguely confused look on their faces.
This is one of the reasons why.
