December 1, 2025 - Cloudy Pacific Northwest Skyscape Timelapse Video | 4K 60fps

December 1st in the Pacific Northwest started under a thick blanket of clouds, with nearly complete cloud cover at 100%. Low clouds dominated the sky at around 92%, while mid-level clouds were also prevalent at 88%. This extensive cloud cover created cool temperatures averaging 36.4°F. Surface winds were gentle, averaging just 0.8 mph, with slightly stronger winds at 100 meters, averaging 1.2 mph. The winds at both altitudes experienced several shifts in direction, leading to a dynamic environment where the low clouds began to drift. With such light winds, there was little movement in terms of cloud dynamics, and although precipitation was absent, the sky felt heavy with moisture. As the day progressed into midday, the scene transformed significantly. By this time, surface winds increased slightly to an average of 1.1 mph, while winds at 100 meters saw a minor increase to 1.3 mph. The cloud cover remained dense at 96.5%, but a striking shift occurred as the low clouds nearly vanished, dropping to just 14%. High clouds continued to dominate, making up almost all of the remaining cloud cover. This substantial change allowed the high clouds to move rapidly across the sky, driven by the stronger winds aloft, which showed signs of conflicting directions compared to the near-still surface winds. The turbulence created by these differing wind patterns contributed to minor but noticeable layering effects, as the high clouds raced in varied directions, creating a textured appearance in the muted winter sky. As evening approached, the weather showcased its final transformations. Surface winds remained mild, holding steady at an average of 1.1 mph, while winds at 100 meters picked up to 2.1 mph. This subtle increase brought a bit more life to the atmosphere, but cloud cover remained significant at 96.3%. Low clouds persisted at a mere 0.3%, with mid-level clouds making a modest appearance at 13.7% and high clouds continuing to blanket the sky at 96.0%. The turbulent interactions between the layers of wind persisted, leading to a mesmerizing tapestry of high-altitude clouds that drifted swiftly, creating a captivating visual display. This weather pattern highlighted the fascinating interplay between calm surface conditions and the more dynamic upper atmosphere, showcasing the rich complexity of Northwest skies during the winter months. Enjoy this stunning weather transformation in 4K Ultra HD at 60fps, capturing the beauty of the Pacific Northwest sky.
