December 10th, 2025 Timelapse
On December 10th, the day began under the cover of a thick, overcast sky, with cloud cover reaching a full 100%. At the surface level, winds averaged 13.1 mph, while at 100 meters, they were significantly stronger, averaging 22.8 mph. This discrepancy between surface and higher altitude winds created a bit of turbulence, as the low clouds, predominantly made up of 100% coverage, were trying to keep pace with the faster-moving winds aloft. The low clouds, combined with mid-cloud coverage around 45% and nearly complete coverage of high clouds, created a monochromatic scene in the sky as the temperature sat comfortably at 55.9°F. Despite the abundant cloud cover, there was no precipitation to speak of in the morning, resulting in a rather tranquil, albeit gray, atmosphere.
As the day progressed into midday, the conditions remained largely consistent, but subtle changes began to occur. Surface winds slightly decreased to an average of 12.2 mph, while winds at 100 meters dropped to 21.3 mph. The cloud cover continued to hold steady at 100%, with low clouds still fully present, mid-cloud coverage increasing to 96%, and high clouds also at 100%. The interaction of the winds at different layers continued to create turbulence, as the stronger winds aloft created waves and shifts in the lower cloud layers. The clouds danced across the sky, more visibly shifting and swirling as the midday temperature nudged up to 56.4°F. Light precipitation began to fall, accumulating to 0.04 inches by this point, adding a soft, rhythmic patter to the already muted ambiance.
By the evening, the weather maintained its cloudy persona, with cloud cover still at a full 100%. The surface winds further calmed to an average of 11.7 mph, while winds at 100 meters decreased to 20.2 mph. The low clouds remained steadfast at 100%, but the mid-cloud layer thinned considerably, dropping to 54%. High clouds continued to dominate, reaching almost 100% coverage. This layering effect provided a more dramatic visual as the lower clouds began to shift more slowly, influenced by the calmer surface winds. As night approached, the temperature slightly dipped to 56.1°F, and the precipitation added an additional 0.01 inches, leaving the day’s total at 0.19 inches. The overall atmosphere was one of subdued beauty, marked by the serene movement of layered clouds and the gentle interplay of winds, making for an intriguing winter day in the Northwest.
