The earliest winter since 1896 arrives at 6:12 AM tomorrow, December
21st. The Old Farmer's Almanac describes the First Day of Winter:
"The word solstice comes from the Latin words for "sun" and "to stand
still.” In the Northern Hemisphere, as summer advances to winter, the
points on the horizon where the Sun rises and sets advance southward
each day; the high point in the Sun’s daily path across the sky, which
occurs at local noon, also moves southward each day. At the winter
solstice, the Sun’s path has reached its southernmost position. The next
day, the path will advance northward. However, a few days before and
after the winter solstice, the change is so slight that the Sun’s path
seems to stay the same, or stand still. The Sun is directly overhead at
"high-noon" on Winter Solstice at the latitude called the Tropic of
Capricorn. In the Northern Hemisphere, the solstice days are the days
with the fewest hours of sunlight during the whole year."
Why is there such a large lag between the first day of winter and the coldest day of the year?
"Answer: This is the shortest day of the year—the time
when the Sun reaches its southernmost point in the sky. Although this
part of Earth is cooling, its great thermal mass still retains some heat
from the summer and fall. As the gradual cooling process continues over
the next two months, temperatures will continue to fall, and the
coldest temperatures will be recorded. The same pattern holds true for
the summer solstice in June, as the year's highest temperatures are
recorded later, in July and August."
So stay warm, dream about the planting to be done, the weeding to be done, the watering to be done, and the spring that is sure to come.
