August 29th, 2026 Timelapse
On August 29th, the morning dawned with a gentle breeze and a cool temperature averaging 55.4°F. Surface winds were quite mild at around 4.9 mph, while winds aloft at 100 meters picked up to a more brisk 8.6 mph, creating a noticeable difference that hinted at some turbulence. The cloud cover was relatively sparse, with an average of 34.2%, composed mostly of low clouds at 29.2% and a smaller fraction of mid-level clouds at 12.6%. A light drizzle was evident, yielding about 0.03 inches of precipitation, suggesting that the combination of low cloud cover and surface winds might have contributed to the damp conditions. The low winds at the surface contrasted with the stronger upper winds, hinting at turbulence as these differing layers interacted.
As the day progressed into midday, conditions evolved noticeably. Surface winds increased slightly to an average of 8.3 mph, and the winds at 100 meters also rose to 11.5 mph, maintaining that layer of wind shear between the surface and aloft. The cloud cover thickened, reaching an average of 48.2%, characterized by a denser presence of low clouds at 33.0% and mid clouds at 25.2%. The interaction between the faster-moving winds aloft and the slower surface breezes led to a dynamic sky where the clouds shifted and morphed, creating a sense of motion overhead. This resulted in a dramatic yet smooth transition as the clouds moved purposefully across the sky, enhancing the overall atmosphere without any significant turbulence affecting the ground.
In the evening, the weather began to settle down as the clouds dissipated significantly, leading to an average cloud cover of just 10.3%, dominated by low clouds at 6.0% and mid clouds at 5.8%. By this time, surface winds had picked up slightly to 9.8 mph, while aloft winds at 100 meters reached around 14.9 mph, maintaining the persistent wind shear that had been characteristic throughout the day. The diminishing cloud cover allowed for clearer skies, and the evening temperatures stabilized around 62.8°F, providing a pleasant end to the day. This transition marked a calming period where the day's earlier cloud dynamics gave way to a more tranquil atmosphere, revealing the beauty of a late summer evening in the Northwest.
