September 15th, 2026 Timelapse
On September 15th, the day began under a thick blanket of clouds, as the sky was dominated by a staggering 96.5% cloud cover. Low clouds hovered at 6.8%, while mid and high clouds were particularly prevalent, comprising 85.2% and 84.0%, respectively. Surface winds were gentle, averaging just 2.5 mph, and at 100 meters, they increased slightly to 4.2 mph. Despite the light winds, the cloud layers were in constant motion, influenced by the winds aloft. The high cloud layer, moving faster than lower tiers, created a sense of depth as they drifted in different directions, casting shadows across the landscape below. A light drizzle contributed to the morning’s dampness, with a total precipitation of 0.01 inches, just enough to moisten the ground but not disrupt the tranquil morning ambience.
As midday approached, conditions shifted subtly yet noticeably. Surface winds increased slightly to an average of 3.3 mph, while winds at 100 meters edged up to 4.4 mph. The mid and high clouds began to thin, resulting in an overall reduction in cloud cover to 85.5%, with low clouds rising significantly to 63.8%. The interplay of wind layers became more pronounced during this time, as the growing discrepancy between the surface winds and those aloft led to minor turbulence and wind shear. The mid-level clouds, now more prominent, moved briskly, while the high clouds appeared to lag behind. This dynamic resulted in a striking visual effect, with layers of clouds shifting in unison yet maintaining a distinct separation that caught the eye.
In the evening, the weather continued to evolve, with surface winds reaching an average of 3.9 mph and winds aloft at 100 meters climbing to 6.6 mph. The cloud cover further diminished to 49.2%, as low clouds settled at 34.5% and high clouds dwindled to 8.8%. The layered cloud structure remained evident, showcasing a beautiful tapestry of varying shades of gray and white against the deepening blue sky. The evening brought about a slight uptick in precipitation, totaling 0.02 inches, likely due to the lingering moisture in the atmosphere. The combination of increased wind speeds at altitude and reduced cloud cover led to a clearer sky, providing a captivating contrast to the earlier dense cloud formations. Overall, the progression of the day's weather showcased a fascinating interaction of wind, clouds, and precipitation, each element continuously influencing the other as the sun began to set.
