December 15th, 2025 Timelapse
On December 15th, the day began under a thick veil of clouds as the morning unfolded. Surface winds averaged 12.8 mph, while winds at 100m reached a brisk 22.8 mph, creating a notable contrast that hinted at turbulence due to wind shear. The sky was completely overcast, with low clouds completely covering the horizon at 100% and mid-level clouds at 73.3%. High clouds were also present at 28.7%, contributing to the dense cloud cover that filtered the soft morning light. Light precipitation of 0.06 inches fell during this period, mixing with the cool morning air that averaged 52.5°F. The conflicting speeds between the surface winds and those aloft caused a dynamic atmosphere, leading to fast-moving low clouds that scudded across the sky.
As the day progressed into midday, conditions evolved slightly but remained characteristically gray. Wind speeds at the surface dipped to an average of 11.2 mph, while the winds at 100m decreased slightly to 19.7 mph. The cloud cover persisted at a full 100%, but the composition shifted; low clouds decreased to 85%, mid clouds saw a drop to 29.5%, and high clouds surged to 74%, creating a multi-layered sky. This interplay of wind dynamics continued to foster turbulence as the stronger winds aloft pushed against the slower-moving surface winds. The visible effect was a kaleidoscope of clouds racing in different directions, creating a mesmerizing display that reflected the constant movement and conflict between the atmospheric layers. During this time, the temperature warmed up to an average of 57.9°F, accompanied by a slight increase in precipitation to 0.09 inches.
By the evening, a notable transformation took place as cloud cover began to recede, revealing glimpses of a less saturated sky. The surface winds averaged 10.7 mph, while winds at 100m remained relatively stable at 19.4 mph, maintaining that dynamic difference. Low clouds diminished significantly to only 7.3%, mid clouds to 16.3%, and high clouds settled at 24%, allowing for a more open view of the dusk sky. The day closed without additional precipitation, and the temperature settled at a comfortable average of 54.7°F. The interplay of wind shear persisted, but the decreased cloud cover created a more tranquil atmosphere, with subtle layering effects showing as the light began to fade. This gradual change from a stormy morning to a clearer evening illustrated nature’s tendency to evolve, revealing the beauty hidden beneath those thick clouds throughout the day.
