December 9th, 2025 Timelapse
On December 9th, the morning unfolded under a blanket of thick clouds, with an average cloud cover of 100 percent. Surface winds were gentle, averaging around 3.0 mph, while winds at 100 meters increased to 6.1 mph, creating a noticeable wind shear that contributed to some turbulence in the lower atmosphere. The low cloud layer accounted for 61.7 percent of the overall cover, while both mid and high clouds completely filled the sky, resulting in an almost uniform grayness. The temperature hovered around a cool 45.3°F, and light precipitation of 0.10 inches fell intermittently, giving the air a damp quality. Overall, the morning set a somber tone, with clouds drifting slowly, dictated by the subtle surface winds below.
As midday approached, conditions evolved slightly while maintaining an overarching cloud cover. Winds at the surface picked up slightly, averaging 3.7 mph, while winds at 100 meters increased to 8.3 mph. This increase in altitude wind speed contributed to a more dynamic atmosphere, with mid and high clouds continuing to dominate the sky and create an impressive display as they moved at different speeds. The lower cloud layer thinned somewhat, dropping to 33.2 percent coverage, allowing for a brief moment of contrast against the dense mid and high clouds that remained steadfast. The slight rise in temperature to 45.7°F accompanied a mild drizzle with 0.03 inches of rain, which was consistent with the cloudy backdrop, while the conflicting wind patterns between the surface and higher altitudes resulted in some turbulence, causing the clouds to appear to ripple and shift more dramatically.
By evening, the weather settled into a distinctive pattern as surface winds increased to an average of 6.8 mph, while winds at 100 meters reached 12.9 mph, intensifying the turbulence and wind shear already present. The cloud cover remained at a steadfast 100 percent, with low clouds now fully encapsulating the sky, consistent with earlier observations. The temperature rose slightly to 46.0°F, and light rain continued, contributing a total of 0.02 inches as the day closed. The conflict between the faster-moving winds aloft and the slower surface winds created layered and dynamic cloud formations, giving the sky a textured, almost three-dimensional quality. This layered effect, combined with the persistent drizzle, wrapped up the day with a sense of completion, marking a day dominated by clouds, gentle winds, and a steady rhythm of precipitation.
