September 25th, 2026 Timelapse
On September 25th, the day began under a heavy blanket of clouds, with an astonishing 99.8% average cloud cover enveloping the sky. Surface winds were brisk, averaging 16.3 mph, while winds at 100 meters soared to 27.6 mph. This significant difference resulted in a clear wind shear, as the stronger upper-level winds pushed against the slower surface winds. Low clouds, comprising 94.2% of the total cloud cover, were particularly prominent, moving swiftly through the sky in response to these surface winds. The mixture of mid-level clouds at 82% and high clouds at 69% added depth and texture to the sky. With a light drizzle contributing 0.17 inches of precipitation, the day started on a cool note, with temperatures hovering around 53.4°F, setting the stage for a dynamic atmosphere.
As the day progressed into midday, conditions began to evolve. The surface wind gradually decreased to an average of 11.4 mph, while the winds at 100 meters lessened slightly to 18.2 mph. This decline in wind speed at both levels reduced the intensity of the turbulent interactions that had been present in the morning. The cloud cover also shifted, dropping to an average of 89.5%, with low clouds decreasing to 78.2% and mid-level clouds to 55.5%. High clouds became sparse, contributing only 23% to the overall cloud makeup. The reduction in cloud density allowed glimpses of blue sky and sunlight to filter through, creating a striking contrast against the still-dominant low cloud layers. The gentle interaction of the winds at different altitudes resulted in a more stable atmosphere, leading to a slightly more tranquil sky, though the presence of 0.13 inches of additional precipitation hinted that moisture still lingered.
As evening approached, the weather continued its transformation, with surface winds calming to an average of 9.7 mph and the upper-level winds settling at 15.7 mph. Cloud cover dropped significantly to an average of 24.8%, revealing a remarkable transition from the heavily overcast conditions of the morning. Low clouds retreated to just 12.2%, while mid-level clouds diminished to 16.8%, leaving high clouds nearly absent at only 1.8%. This marked a drastic change, allowing the evening light to bathe the landscape in warmer tones as the temperature climbed to an average of 57.0°F. The day wrapped up with a minimal 0.04 inches of precipitation, suggesting that the earlier rain had made way for clearer skies. The remaining clouds drifted lazily across the horizon, a reminder of the day's earlier turbulence and dynamic tension between the wind layers, which had painted an ever-changing canvas in the sky throughout the daylight hours.
