It is officially Spring! Actually, it was officially Spring yesterday, but I tend to think of Spring as starting on March 21st instead of March 20th. Spring begins with the vernal equinox. This is when the sun crosses over the equator and technically the length of the day and night are equal. Seasons are scientifically defined by the Earth's distance and tilt towards the Sun, but we notice through the change in weather. The severe weather occurs as warm air is moving north and encounters the cold air still being pushed down from the polar regions. It is why we say March comes in like a lion and out like a lamb. Spring ends with the Summer Solstice where Earth's orbit is most tilted towards the Sun. Spring, a wonderful season with the promise of renewal and growth.
