August 11th, 2026 Timelapse
On August 11th, the morning dawned under a thick blanket of low clouds, with an average cloud cover of 96.4%. The surface winds were gentle, averaging around 5.2 mph, while winds aloft at 100 meters reached slightly higher speeds of 7.7 mph, creating a gentle wind shear. This difference in wind speed contributed to a noticeable turbulence as the low clouds, thick and uniform, moved steadily across the sky. With temperatures starting at a cool 57.6°F, the morning atmosphere felt damp and subdued, with no precipitation observed. The low cloud deck obscured the sun, resulting in muted light and a rather gray vista, but it also provided a fascinating contrast as the wind at 100 meters pushed the clouds along more swiftly than those at the surface.
As the day progressed into midday, conditions began to change significantly. The cloud cover reduced to an average of 65.8%, allowing glimpses of clearer skies beneath. The surface winds picked up slightly to an average of 6.2 mph, while winds at 100 meters increased to 8.3 mph. This slight increase in wind speed continued to create a layer of turbulence between the two altitudes, which affected the movement of the remaining low clouds. Some clouds began to break apart and thin out, moving quickly while others lingered lower to the ground. The temperature rose to a comfortable 69.9°F, encouraging a more dynamic atmosphere as the remaining clouds danced across the sky, illuminated by sporadic sunlight breaking through.
As evening approached, the sky continued to evolve, exhibiting a dramatic change in both wind patterns and cloud cover. Average cloud cover dropped to just 8.3%, resulting in a nearly clear sky as the last remnants of the low clouds dissipated. Winds at the surface became stronger, averaging 11.1 mph, while winds aloft surged to 17.0 mph, exacerbating the wind shear effects that had characterized the day. The turbulence caused by the conflicting wind directions created a mesmerizing display in the sky, where the remaining wisps of clouds seemed to race against the backdrop of a deepening twilight. The temperature settled at 68.5°F, completing a day that started under a thick veil but transitioned into a beautifully clear evening, showcasing the ever-changing nature of the Northwest skies.
