It is that time of year again when you easily notice later dawns and earlier sunsets...when the days start getting shorter and cooler weather begins. Last night and today we had a little taste of fall in the air, however the Fall Equinox (approximately equal day and night) officially begins this Saturday at 9:49am.
The fall and spring equinoxes are the only days of the year in which the Sun crosses the celestial equator. Just as the earth's equator divides the sphere of the earth into two hemispheres - northern and southern -, the Celestial Equator divides the apparent sphere of the sky, the Celestial Sphere, into a Northern and a Southern Celestial Hemisphere. Like the equator of the earth, the Celestial Equator lies halfway between two poles. Autumn will end December 20th, winter will start the 21st.
The remainder of our forecast to finish out the week into the weekend looks calm. Weak southerly flow will gradually return slightly warming temps and humidity. Rain chances stay slim to none. However, another front expected to move through the area Sunday with little to no moisture content. This should reinforce fall conditions into early next week as ridging builds in behind the front.
