Winter officially begins in the Northern Hemisphere at 11:28 a.m. on Thursday, Dec. 21.
This marks the winter solstice and shortest length of daylight for any day of the year and winter season.
On Thursday, the sun will be directly over the Tropic of Capricorn. There will be just more than 10 hours and two minutes of daylight in the city of Savannah; similar lengths for surrounding areas.
Beginning on Friday, the length of daylight begins to increase, with more than 10 hours and five minutes between sunrise and sunset by the final day of the year.
It is important to note that this is an astronomical process and moment. While amount of solar radiation does impact weather and climate, the forecast will not reflect any sudden changes as we officially enter the winter season.
