April 30th, 2026 Timelapse
On April 30th, the day began with a blanket of high clouds covering the sky, creating a serene but muted atmosphere as the sun rose at 5:59 AM. The surface winds were nearly calm, averaging just 1.2 mph, while the winds at 100 meters were slightly stronger at 4.6 mph. This gentle breeze at the surface contributed to a stable air mass, allowing the high cloud layer—fully covering 100% of the sky—to drift languidly, devoid of any significant low or mid-level cloud presence. The temperature started cool, averaging 48.2°F, with these high clouds preventing any immediate warming from the sun. The lack of turbulence at this stage indicated a relatively uniform air flow, though the wind speed at higher altitudes hinted at a potential for increased cloud dynamics as the day progressed.
As midday approached, the atmosphere underwent a noticeable transformation. The surface winds picked up slightly to an average of 3.8 mph, while winds at 100 meters increased marginally to 5.0 mph. The high clouds persisted, covering 94.8% of the sky, but began to exhibit a more dynamic character as they were pushed along by the shifting winds aloft. Interestingly, the wind direction underwent significant changes during this period, resulting in swirling patterns that caused the clouds to move in varied directions. This interplay between the faster, higher-altitude winds and the lighter winds at the surface created a subtle turbulence and wind shear effect, leading to a more visually captivating sky filled with rapidly moving cloud formations. The temperature rose to a pleasant 66.2°F, allowing for a brief moment of warmth under the cloud cover.
By the evening, the scene shifted once again as the sun began its descent, casting a warm light even through the thinning cloud layer. The surface winds remained steady at 3.9 mph, but the winds at 100 meters had strengthened to 7.6 mph, indicating a more robust high-altitude flow that was now influencing the cloud dynamics. With only 27.3% of high clouds remaining, the sky opened up significantly, allowing for glimpses of blue to emerge as the clouds began to dissipate. This reduction in cloud cover brought about a clearer horizon, while the lingering winds aloft continued to push the remaining clouds into layered patterns. The temperature peaked at 71.2°F, creating a delightful evening atmosphere free of precipitation, and the interplay of wind layers added a final touch of complexity to the sky, embracing the day with a beautifully evolving weather story.
