September 27th, 2026 Timelapse
On September 27th, the day commenced with a tranquil morning characterized by gentle breezes and a cool temperature averaging 46.7°F. Surface winds were light, averaging only 2.0 mph, which allowed for a calm atmosphere at ground level. However, at an altitude of 100 meters, winds picked up to a brisk 5.6 mph, creating a notable difference that hinted at developing turbulence as the day progressed. Cloud cover was relatively sparse, with an average of 25.5%, primarily comprised of low clouds (17.2%) and a smattering of mid-level clouds (9.8%). The high clouds contributed a mere 2.0% to the overall picture, giving the sky a mostly clear appearance as the sun began its ascent. The gentle winds at the surface allowed for a slow drift of the low and mid-level clouds, primarily moving eastward, while the higher clouds appeared to be slightly more mobile, hinting at the stronger breezes aloft.
As the day unfolded into midday, conditions evolved significantly. The temperature rose to a comfortable 61.0°F, and surface winds increased to an average of 5.1 mph, still relatively mild but stronger than the morning. Winds at 100 meters climbed to 7.1 mph, maintaining a steady direction that continued to push clouds across the sky. The cloud cover diminished considerably, dropping to an average of only 12.0%, with low and mid-level clouds nearly absent and high clouds forming 11.8% of the total. This shift in cloud dynamics was a visual delight, with wispy high clouds moving gracefully, often creating streaky patterns against the bright blue backdrop. The interaction between the surface and higher winds remained stable, but the light surface winds contrasted with the slightly stronger aloft winds, creating a minor wind shear that occasionally stirred up turbulence, causing some of the higher clouds to swirl momentarily as they passed through different wind layers.
By the evening, the weather settled into a serene and clear state, with temperatures rising slightly to an average of 63.1°F. Cloud cover completely vanished, leaving an unblemished sky, which is a rare treat in the Pacific Northwest. Surface winds remained steady at 5.1 mph, while winds at 100 meters increased further to 9.1 mph. The lack of cloud cover allowed for a brilliant view of the sunset, with the evening light casting a warm glow across the landscape. The absence of clouds meant no precipitation to speak of, and the winds remained consistent throughout the day, with no significant wind shear or turbulence to disrupt the tranquil evening. Overall, September 27th showcased a gradual transformation from a cool, cloudy morning to a pleasant, clear evening, providing a lovely backdrop for the transition from day to night.
