The Fall season officially arrives Saturday night.
Cooler weather, coincidentally, is on the way just in time for the change in seasons for parts of the country that have seen record warmth the last few days.
The Autumnal Equinox Will happen Saturday evening, the sun will pass directly over the earths equator. The tilt of the Earth's axis in relation to the sun controls the seasons along with the distance of the Earth from the sun along it's elliptical orbit.
As the days get shorter across the N Hemisphere average temperatures will gradually fall.
Here is a view of what the equinox will look like from space. The day and night time line across the Earth will be vertical, and line marking day and night will be oriented north-south.
From NOAA National Environmental Satellite, Data and Information Service (NESDIS)which manages NOAA's constellation of environmental satellites and the data they provide.
