      December 2024 Observations and Discussion

      As holiday lights brighten streets and the season of cheer unfolds, Dec. 21 marks the winter solstice a reminder that the longest hours of darkness of the year is upon us. The winter solstice occurs this year on Saturday, Dec. 21 At 4:20 a.m. ET, the solstice will take place, marking "the beginning of winter in the Northern Hemisphere and summer in the Southern Hemisphere. All locations north of the equator see daylight shorter than 12 hours and all locations south see daylight longer than 12 hours. The winter solstices are considered to be the start of the astronomical winter. And the start of the Southern Hemisphere summer. These seasons are based on Earth's natural rotation. In contrast, meteorological seasons divide the year into three-month groups based on temperature patterns, making them more closely aligned with our monthly civil calendar than astronomical seasons. After the solstice, every day will have a little more sunlight than the one before. By the time we reach the summer solstice on June 20, 2025, it will be the longest day of the year.

      East wind picking up here and a ridiculous 54 degrees. ECMWF shows 30s tomorrow night for this area. Even that would seem special right now.
