August 21st, 2026 Timelapse
On August 21st, the day began under a shroud of nearly complete cloud cover, with the sky obscured by a remarkable 99.6% of clouds—mostly high clouds at 95.6% and low clouds at 61.8%. Surface winds were gentle, averaging around 4.6 mph, while winds at 100 meters above the ground were slightly stronger at 7.3 mph. This gentle breeze at the surface created a stable environment, allowing the thick blanket of clouds to linger without much disturbance. The temperature started cool at an average of 59.5°F, contributing to a rather subdued morning. As the morning unfolded, there were no signs of precipitation, but the dense cloud cover was a constant reminder of the atmospheric moisture present.
As midday approached, conditions evolved but remained consistently cloudy, with cloud cover reaching a full 100%. Surface winds remained almost unchanged at 4.7 mph, while winds aloft at 100 meters decreased slightly to 6.2 mph. The high clouds continued to dominate the skyline, while the low clouds receded to just 9.8%. This dynamic shift in cloud layering occurred as the gentle surface wind likely contributed to the high cloud formation, which drifted lazily across the sky. The air remained still and warm, with the temperature rising to an average of 69.4°F, creating a comfortable, if slightly humid, atmosphere. Interestingly, the relatively calm winds at the surface contrasted with the conditions aloft, which may have introduced some minor turbulence, though it went unnoticed due to the uniform appearance of the cloud cover.
By the evening, conditions began to shift subtly yet noticeably. The surface wind picked up slightly to an average of 6.2 mph, and winds at 100 meters increased to 8.9 mph, introducing a bit more vigor into the atmosphere. Despite the increase in wind speed, the cloud cover remained dense, with 97.3% of the sky still obscured by high clouds. Low and mid-level clouds were virtually absent, leading to a layered effect that gave the sky a dramatic yet tranquil appearance. The temperature dropped slightly to an average of 68.1°F, marking a gentle transition into the evening. As the sun set, the ongoing wind shear between the surface and higher altitudes created a fascinating interplay of cloud movement, but with no precipitation in sight, the day concluded peacefully under a canvas of drifting clouds.
