September 23rd, 2026 Timelapse
On September 23rd, the day began under a thick blanket of clouds, with an average cloud cover of 91%. At the surface, winds were gentle, averaging only 1.8 mph, while at 100m, winds picked up slightly to around 2.7 mph, creating a subtle yet noticeable difference in airflow near the ground. The clouds were predominantly high, covering 80.8% of the sky, with mid-level clouds contributing 60.2%, and a small fraction of low clouds at 14.2%. This confluence of cloud types and low wind speeds suggested a calm start to the day, with no precipitation expected, even as the temperature settled at a cool 52.3°F. However, the air aloft was poised for change, as the winds at higher altitudes began to clash with the gentle currents below, hinting at potential turbulence as the day progressed.
As midday approached, the atmosphere became more active. Surface winds increased to an average of 3.9 mph, while winds at 100m rose to 5.2 mph, suggesting a gradual strengthening of the air currents. The cloud cover thickened slightly to 93.2%, with low clouds now comprising 60.5% of the total, while mid-clouds diminished to 19.8%, and high clouds remained substantial at 85.8%. This shift in cloud dynamics was a direct result of the stronger surface winds, which began to move the lower cloud layers more quickly across the sky. The winds aloft, still at odds with those below, created a bit of turbulence, making the clouds appear to swirl and shift in different directions, providing an intriguing spectacle as the midday light filtered through the layers.
By evening, conditions shifted once again. Surface winds grew slightly stronger, averaging 5.7 mph, and winds at 100m increased further to 8.7 mph, signaling a continued rise in overall wind activity. This led to a noticeable decrease in cloud cover to 62.6%, a refreshing change that allowed for more of the blue sky to peek through. The low clouds dropped to 17.4%, while mid-clouds were nearly absent at only 5.0%, and high clouds lingered at 57.6%. The interaction between the layers continued to create a dynamic sky, where the faster-moving winds aloft pushed the remaining clouds into sweeping formations, casting shadows and highlighting the layers beneath. As temperatures settled at 60.8°F, the day wrapped up with a unique blend of shifting clouds and strengthening winds that had transformed the quiet morning into a lively evening sky.
