The first chart shows only the number of flights canceled each day throughout the month. It makes clear the dramatic rise that begins to tick upward in the month's second week then increases more steeply in the month's later weeks.
The chart below shows the increasing number of flight cancellations in the context of the declining number of flights departing as the month advances.
