March 21st, 2026 Timelapse
On March 21st, the day began with gentle, stable conditions as the sun rose at 7:12 AM. The surface wind averaged a calm 6.6 mph, while winds at 100 meters were significantly stronger at 11.9 mph, creating a notable wind shear. This disparity in wind speeds contributed to the smooth, albeit slow-moving low clouds that comprised nearly 2.8% of the sky. The temperature started fairly cool at an average of 40.4°F. With nearly no mid or high clouds present, the low cloud deck moved slowly in a gentle easterly direction, influenced by the stronger winds aloft. Although there was only a trace of precipitation recorded—about 0.01 inches—the atmosphere felt expectant, hinting at the evolution of conditions as the day progressed.
As the day unfolded, the weather shifted notably by midday, with surface winds decreasing slightly to an average of 5.7 mph and 100-meter winds relaxing to 7.6 mph. The cloud cover increased dramatically to 28.5%, dominated by low clouds that remained anchored close to the surface while moving more rapidly than at dawn. The temperature climbed to a mild 48.0°F, fostering a soft, textured sky. The interaction between the slower surface winds and the quicker upper-level winds resulted in an engaging display of cloud dynamics. The low clouds churned and billowed, creating a scene of layered effects that reflected the gentle turbulence caused by the conflicting wind layers. Despite the increase in moisture in the air, the absence of mid and high clouds allowed a serene blue background to peek through, offering a visually compelling contrast.
By the evening, as the sun set at 7:26 PM, conditions began to stabilize further. The surface wind picked up slightly, averaging 8.7 mph, while the winds aloft increased to 13.7 mph. The cloud cover dramatically dropped to just 0.7%, signaling a significant clearing trend. The low cloud layer, which had been a presence throughout the day, thinned out to nearly nothing, leaving the sky brightening and open. The contrast between the remaining low level winds and the stronger winds above continued to create subtle turbulence in the atmosphere. As temperatures held steady at 48.0°F, the remnants of earlier cloud formations faded, allowing for a tranquil evening sky. Overall, March 21st displayed a variety of atmospheric dynamics, showcasing the complex interplay between winds and cloud cover throughout the day.
