Today will be the first day of winter and the shortest day of the year, as the Winter solstice arrives at 11:48pm EST. This means North of the Arctic Circle towards the North Pole there is no direct sunlight at all during this time of the year.
The Solstice is an astronomical event that happens twice a year. Once in summer and once in winter. The Winter Solstice happens when the North Pole is tilted furthest away from the sun which is its most southerly declination of -23.5.
Ironically, as we head into the first full day of winter, temperatures will be mild with highs in the low 60s. It will only get warmer from there. Record highs are forecasted for Christmas eve as temps soar into the low 70s!
Happy Winter Solstice!
