December 11th, 2025 Timelapse
On December 11th, the morning began with an enveloping shroud of clouds that cloaked the sky entirely, with cloud cover reaching a full 100% across all layers. Surface winds were gentle, averaging just 1.5 mph, while winds at 100 meters rose to 2.6 mph, indicating a tranquil atmosphere below. However, the subtle conflict between these low-level winds and slightly stronger currents aloft set the stage for a dynamic morning. Low clouds hovered thickly, matching the high cloud coverage of about 75%, providing an atmospheric canvas that felt both heavy and still. As precipitation accumulated to 0.13 inches, the moisture-laden air contributed to that characteristic damp chill, with temperatures hovering around a mild 52.9°F. The calm surface winds, combined with low and mid-level clouds, hinted at turbulence higher up, where the winds were beginning to churn in different directions.
As the day progressed into midday, conditions shifted subtly yet significantly. By this time, surface winds increased slightly to an average of 2.0 mph, while winds at 100 meters picked up to 3.9 mph, reflecting a gentle but noticeable uptick in movement. The cloud layers began to show signs of motion, with low clouds remaining dense at 100%, while mid clouds diminished to 59.5%, allowing for a glimmer of light to peek through. High cloud cover was at 96.2%, creating a complex visual tapestry of swirling patterns against the backdrop of a grey sky. The differing wind directions at various altitudes contributed to notable wind shear, causing the faster-moving clouds aloft to shift in a way that occasionally conflicted with the slower, denser clouds below. This resulted in a captivating display of layered clouds, as the winds aloft pushed the mid and high clouds more rapidly across the sky, while the low clouds remained anchored, creating a fascinating juxtaposition.
By the evening, the weather settled into a more cohesive pattern, though not without lingering complexities. Surface winds eased back down to an average of 1.0 mph, while winds at 100 meters slowed slightly to 3.0 mph. The cloud cover remained steadfastly at 100%, with low clouds still fully obscuring the sky, mid-level clouds at 68.7%, and high clouds increasing to 98.7%. This blend reinforced the sense of a sky dominated by layers of grey, with the wind dynamics continuing to create pockets of turbulence as lower winds met the more vigorous currents aloft. Precipitation added a modest 0.02 inches to the day's total, bringing the cumulative rainfall to 0.31 inches. As temperatures drifted slightly to 54.7°F, the evening sky retained a character of depth and layering, displaying the intricate relationships between the wind patterns and cloud cover that defined the day.
