February 17th, 2026 Timelapse
On February 17th, the morning began under a dense canopy of clouds as the sky was completely covered, with cloud cover reaching nearly 100 percent. At the surface, winds averaged around 7.5 mph while at 100 meters, they were considerably stronger at 13.4 mph, indicating a significant wind shear that would create some turbulent conditions. This difference in wind speeds contributed to the movement of the low, mid, and high clouds, with low clouds making up 86 percent of the sky. The high clouds were particularly notable, filling nearly all of the upper atmosphere at 99.2 percent. As temperatures hovered around a chilly 34.8°F, light precipitation was already underway, contributing to the 0.39 inches expected for the day. The conflicting wind directions at different altitudes likely enhanced the cloud dynamics, leading to swirling patterns that could be seen in the shifting clouds.
As the day progressed into midday, temperatures climbed to an average of 40.0°F, and the persistent overcast remained largely intact, with total cloud cover dropping slightly to 99.8 percent. While surface winds remained consistent at about 7.3 mph, winds aloft at 100 meters decreased to an average of 10.3 mph, resulting in less turbulence than earlier. The mid-level clouds became more pronounced, showing a 97.2 percent coverage, whereas low clouds decreased to 78.5 percent. Despite this minor shift, the overall cloud structure remained thick and layered. A slight drizzle was recorded, adding 0.02 inches of precipitation, a small but persistent reminder of the moist air mass in place. The turbulence created by the differing wind velocities continued to influence the cloud formations, resulting in some interesting visual dynamics as clouds raced by at varying speeds.
By evening, conditions shifted further as surface winds dropped to a gentle 3.0 mph and aloft winds diminished to 4.5 mph, reflecting a calming atmosphere. The cloud cover decreased to an average of 93.2 percent, with low cloud coverage now at 53.2 percent and high clouds at 79.2 percent, indicating a gradual thinning of the cloud layers. As temperatures cooled to an average of 38.0°F, the earlier precipitation ramped up, totaling 0.16 inches, giving the day a soft, drizzly finish. The layered clouds, influenced by the light winds, created a soft texture in the sky, while the decreasing wind speeds reduced turbulence, allowing for a more tranquil evening. The interplay of these elements outlined a day marked by a dramatic transformation in cloud dynamics, where the lingering moisture and shifting winds shaped a uniquely atmospheric experience.
