December 19th, 2025 Timelapse
On December 19th, morning dawned cool and overcast, with temperatures averaging around 38.8°F. The surface winds were light, averaging just 3.7 mph, while at 100 meters, stronger winds blew at 8.2 mph, creating a notable contrast and resulting in a gentle turbulence near the ground. This difference in wind speed contributed to the low and mid-level cloud cover, which was quite dense at 82 percent overall. Low clouds constituted about 41.3 percent of the sky, and mid-level clouds made up 72 percent, hanging heavily as a gray blanket across the landscape. Light rain began to fall, registering 0.01 inches of precipitation, further accentuating the moody morning ambiance. The winds at these higher altitudes pushed the clouds toward the east, setting the stage for the day's evolving weather dynamics.
As the day progressed toward midday, the temperature rose to an average of 43.2°F, accompanied by a slight increase in surface wind speeds, which reached 8.2 mph. Winds at 100 meters continued to strengthen, averaging 12.2 mph, creating a robust draft that helped to clear some of the denser cloud cover. By this time, total cloud cover had decreased to 78 percent, with low clouds now at 35.5 percent and mid-level clouds at 68.5 percent. The interplay between the lighter surface winds and the stronger upper winds created a fascinating display of moving clouds, as the mid-level cloud deck streamed across the sky with a sense of urgency. The wind shear between these layers resulted in a few areas of turbulence, causing the clouds to churn and shift in captivating patterns, further enhanced by another light precipitation event that added 0.05 inches to the morning's accumulation.
In the evening, conditions shifted yet again, with temperatures settling around 41.5°F and surface winds averaging 6.6 mph. The winds aloft remained relatively consistent at about 12.1 mph, which continued to create distinctive layers in the cloud cover. The total cloud coverage dipped to 63.3 percent, with low clouds at 38.7 percent and mid-level clouds at 46.3 percent. This layering resulted in an intriguing visual effect as the clouds drifted at different speeds, leaving gaps that occasionally illuminated the sky with a muted glow from the setting sun. The conflict between the slower surface winds and the brisker winds above caused additional turbulence, creating dynamic shifts in the cloud formations. By the end of the day, a total of 0.06 inches of precipitation was recorded, concluding a day characterized by layered clouds, gentle rains, and a captivating interplay of wind and weather dynamics.
