December 31st, 2025 Timelapse

On December 31st, the morning began with a crisp atmosphere, as temperatures hovered around 34.6°F. Surface winds were quite gentle, averaging only 3.5 mph, which made for a calm start to the day. However, at 100 meters, the winds picked up to an average of 8.8 mph, creating a noticeable contrast between the surface and upper levels. This difference in wind speeds initiated a layering effect in the sky, where low clouds formed at 2.7% coverage and mid-level clouds floated above at a modest 9.3%. The light winds at the surface allowed for a serene mix of these clouds, resulting in a mostly clear sky interspersed with gentle patches of white.

As the day unfolded into midday, conditions began to shift significantly. The surface wind remained consistent, averaging 3.6 mph, but the winds at 100 meters dropped to 5.5 mph. This slight decrease in upper-level winds resulted in a more stable atmosphere, allowing for an increase in overall cloud cover to 29.5%. The low clouds rose to 17.8% coverage, while mid-level clouds decreased to just 1.8%, making way for a higher presence of clouds at 13.5%. The interaction of these varying cloud layers created a dynamic scene, with the higher clouds moving swiftly compared to the more stable low clouds below. This layering effect contributed to a softening of the daylight, casting a muted glow across the landscape.

By evening, the weather had transformed dramatically. Cloud cover surged to an impressive average of 82.3%, dominated by high clouds at 79.0%, with low clouds remaining relatively minimal at 7.7%. Surface winds slowed further to just 2.1 mph, while upper winds picked up slightly to 6.5 mph, leading to a notable level of wind shear as the two layers conflicted. This turbulence resulted in fascinating visual effects in the sky, as the high clouds billowed and danced across the horizon, contrasting with the stillness below. Temperatures dipped to an average of 40.8°F as the day concluded, encapsulating the transition from a bright, clear morning to a rich tapestry of clouds that painted the evening sky.
