It’s the coolest morning we have seen since early June to possibly late May. Temperatures have fallen to the low 40s in some places and we may see some communities off to the northeast falling below 40 degrees. It’s just another sign that the season change is upon us.
Officially fall begins at 10:29 PM on September 22. This is when the Autumnal Equinox will occur. That’s one of two times a year when the earth is half way between the Summer Solstice and the Winter Solstice. It is always interesting for me that the Northern Hemisphere’s winter months marks the time when the earth is the closest to the sun. While our orbit is closer our angle facing the sun is lower due to the tilt of the Earth. During our summer months, the Northern Hemisphere tilts towards the sun. The Southern Hemisphere tilts away from the sun. During the winter the opposite is true with the Northern Hemisphere tilting away from the sun. This difference in angles is the main player in our seasons.
