March 15th, 2026 Timelapse
On March 15th, the morning began under a thick blanket of clouds, with 100% cloud cover dominating the sky. The surface winds were gentle, averaging just 1.5 mph, while a slightly stronger breeze of 3.8 mph was recorded at an altitude of 100 meters. This created a distinct layer of wind shear, with the winds aloft being more than twice as strong as those at the surface, leading to subtle turbulence that could be felt by those venturing outdoors. The temperature was a chilly 36.9°F, and the clouds were predominantly mid-level, with high clouds also making up a significant portion of the sky. The atmospheric conditions were stable, and no precipitation was recorded, adding to the stillness of the morning.
As the day progressed towards midday, the clouds remained firmly in place, still covering the sky completely. Wind patterns shifted slightly, with surface winds increasing to an average of 2.6 mph, while the winds at 100 meters rose to 4.6 mph. The persistence of the mid and high clouds, now covering 100% of the sky with nearly 96% being high clouds, created a uniform gray backdrop. Although the winds aloft were still stronger than those at the surface, the lack of significant turbulence suggested that the different layers were moving relatively harmoniously. The absence of precipitation continued, allowing for a dry interlude under the blanket of clouds, which moved slowly, imparting a soft, muted light across the landscape.
By the evening, the weather began to show slight but noticeable changes. Surface winds picked up to an average of 5.0 mph, while winds at 100 meters increased significantly to 10.0 mph, further emphasizing the existing wind shear. The temperature dipped slightly to 43.0°F, and the cloud cover evolved to include lower clouds for the first time, making up 63.6% of the overall cloud composition. The high clouds remained, rendering the sky a complete tableau of gray, with layered effects becoming more pronounced as the differing wind speeds at various altitudes interacted. Precipitation finally occurred, amounting to 0.10 inches, contributing to the overall feeling of a wet evening. The combination of stronger winds and persistent cloud cover created a dynamic sky, with clouds shifting at various speeds, painting a picture of the ever-evolving Northwest atmosphere.
