December 6th, 2025 Timelapse
On December 6th, the day began under a thick blanket of clouds, setting the stage for a rather atmospheric morning. The surface winds were gentle, averaging around 4.9 mph, while at 100 meters, they gusted more robustly at 10.2 mph. This disparity in wind speeds created a base for turbulence, particularly as the clouds, comprising 84% of the sky, exhibited a mix of low, mid, and high layers. Low clouds made up 52% of the coverage, while mid-level clouds accounted for 56.5%, and high clouds reached 38%. As precipitation began to fall lightly, totaling 0.06 inches, the movement of the clouds mirrored the stronger winds aloft, drifting steadily as the moisture-rich air rose. The morning conditions hinted at a dynamic day ahead, with the potential for evolving weather patterns.
As midday approached, the weather intensified with a noticeable increase in cloud cover to an impressive 90.8%. The surface winds picked up slightly to an average of 5.7 mph, while the winds at 100 meters decreased to an average of 9.2 mph, creating a more stable environment overall. The mid-layer clouds swelled to cover 69.8%, while high clouds increased to 55%. This change in cloud composition suggested an interaction of moist air at lower altitudes being pushed upwards by the strong winds above. The precipitation rate also rose significantly, accumulating to 0.26 inches, as the gentle moisture-laden winds continued to collide with the lower layers, causing a persistent drizzle. The dynamics of the clouds were fascinating, with some layers moving swiftly in one direction while others remained more stationary, revealing the complex dance of the atmosphere.
As evening settled in, the weather conditions transformed once again. The sky became nearly fully covered with clouds, reaching an extraordinary 99% coverage. The surface winds averaged 5.1 mph, while the winds aloft picked up slightly to 10.7 mph, maintaining the earlier disparity and consequently sustaining turbulence. The low clouds now constituted 49.7% of the total sky, mid clouds decreased to 31.7%, while high clouds surged dramatically to encompass 97.3%. These high clouds, driven by the stronger winds aloft, created a striking visual effect as they swirled above the denser, slower-moving layers below. The total precipitation for the day reached 0.50 inches, highlighting the persistent moisture that had characterized the entire day. The interplay of the different wind patterns and cloud types throughout the evening painted a vivid picture of a day filled with dynamic weather, reminding us of the ever-changing nature of the Northwest skies.
