December 3rd, 2025 Timelapse
On December 3rd, the morning unfolded under a blanket of thick cloud cover, with an average temperature of 39.0°F that set a cool tone for the day. Surface winds were notably light, averaging just 0.9 mph, while winds at 100m hovered slightly higher at 1.2 mph. This minimal wind activity at lower altitudes created a stable atmosphere where the clouds, composed entirely of low, mid, and high formations, exhibited a uniformity that suggested little movement. The low cloud cover was at a staggering 100%, complemented by mid and high clouds at 81.5% and 100% respectively. No precipitation was noted at this stage, but the heavy cloud presence suggested a likelihood of moisture accumulation as the day progressed. Interestingly, the winds at these different altitudes were aligned, hinting at a calmness that contributed to the static, overcast conditions of the morning.
As the day transitioned to midday, the atmospheric dynamics began to shift subtly yet significantly. Surface wind speeds increased slightly to an average of 1.4 mph, while winds at 100m were marginally stronger at 1.6 mph. Despite this increase, the overall cloud cover remained impressively thick, with low clouds at 81.2% and mid clouds reaching nearly complete coverage at 99.0%. This dense layering of clouds was likely influenced by the light winds, which created minimal turbulence and allowed for a more stable cloud structure. However, the mid-level clouds appeared to drift slightly faster than their lower counterparts, creating a dynamic visual effect as they seemed to roll over one another. The day also saw the first hint of light precipitation, with 0.01 inches recorded, suggesting that the moisture content in the clouds was finally beginning to be released. The interplay of wind patterns at different altitudes exhibited some signs of shear, leading to gentle turbulence that animated the cloud formations without causing significant disruption.
In the evening, conditions began to stabilize, with surface winds decreasing back to an average of 0.9 mph and 100m winds settling at 1.4 mph. The temperature crept up slightly to an average of 42.7°F as the day drew to a close. The cloud cover remained exceptionally dense, with low clouds decreasing to 33.3%, while mid and high clouds continued to maintain high percentages at 94.7% and 95.3% respectively. This layered cloud structure created a striking, textured sky that painted a dramatic backdrop for the setting sun. Despite the fading light, the evening skies were still characterized by a gentle movement of high and mid clouds, which were pushed along by the very light upper winds. These interactions hinted at a lingering possibility of turbulence as clouds from different levels continued to interact, leaving a soft but persistent reminder of the day’s earlier activity. As darkness enveloped the landscape, the weather settled into a tranquil stillness, leaving behind the day’s evolving cloud drama to reflect upon as another chapter in the Northwest's ever-changing skyscape.
