December 23rd, 2025 Timelapse
On December 23rd, the day began under a thick canopy of clouds, with the low overcast dominating the sky. Surface winds were calm, averaging just 3.1 mph, while winds at 100m elevation blew slightly stronger at 6.8 mph. This gentle wind at the surface meant that the low clouds, which comprised 56.3% of the total cloud cover, were mostly stagnant. Meanwhile, higher altitudes were saturated with clouds, as evidenced by a staggering 99.7% cloud cover at both mid and high levels. The temperature hovered around a cool 40.4°F, and very light precipitation could be detected, hinting at the moisture-rich atmosphere. The highly stratified cloud layers hinted at potential turbulence, especially as the winds at 100m began to veer in different directions compared to the calmer surface winds.
As midday approached, cloud cover remained complete at 100%, with mid-level clouds dramatically increasing to 82% while low clouds decreased slightly. Winds at the surface picked up a bit, averaging 4.2 mph, while those at 100m reduced to 6.0 mph. This shift in wind speed and direction resulted in an interesting interaction between the various wind layers, creating subtle turbulence and layering effects in the clouds. The mid and high clouds moved swiftly across the sky, influenced by the more robust winds aloft, while the lower clouds lagged behind, producing a stunning visual contrast that highlighted the layered look of the overcast sky. Light rain was noted, with a total of 0.01 inches of precipitation, further adding to the thick, moist atmosphere.
By the evening, conditions shifted slightly, though the cloud cover remained unchanged at 100%. Surface winds fell to an average of 1.5 mph, leading to a particularly still atmosphere. Winds aloft, however, continued to soften, averaging just 3.5 mph at 100m. The continued presence of high and mid-level clouds ensured that the sky remained completely covered, leaving only the faintest glimmers of light as the sun set at 4:30 PM. The conflicting wind directions at different altitudes created a gentle shearing effect, leading to some turbulence, which contributed to the dynamic, yet subdued, motion of the clouds. The temperature dropped slightly to around 43.7°F, capping off a day characterized by rich cloud layers and gentle, yet complex, wind patterns that painted a serene winter sky.
