This animation shows all aircraft flying over the United States during a 24-hour period on a typical day and shows the impact of severe weather on traffic in the New York area.
The U.S. airspace is a busy place. This animation starts at 8 p.m. EDT and runs until 8 p.m. the next evening. Starting around 5:00 a.m., activity at Memphis, home of FedEx, picks up first, and then the morning flights begin leaving the East Coast. The next big activity is at Chicago, and then Dallas and Denver, and continues to propagate westward as the day begins. During peak times of the day, over 5000 aircraft will be sharing the airspace over the U.S.

With so much going on, a glitch or delay in one place can cause problems throughout the system.
And the biggest source of delays for air travel is...
...WEATHER...
Low ceilings and visibility account for the majority of these delays, but thunderstorms also play a large role, especially during the convective weather season.
