November 18th, 2025 Timelapse
On November 18th, the day began under a thick blanket of clouds, with an impressive average cloud cover of nearly 99.8%. The surface winds were gentle, averaging only 1.6 mph, while winds at 100m were slightly stronger at 2.7 mph. This minimal wind movement at the surface allowed the low clouds, comprising about 27.2% of the total cloud cover, to remain stable and sluggish. Mid-level clouds were much more prevalent, occupying 83.8% of the sky, and high clouds added to the mix with 57%. The temperature hovered around a brisk 43.3°F, and light precipitation of 0.01 inches began to fall intermittently, adding to the dreariness of the morning. There was a subtle turbulence present due to the conflicting directions of surface winds and those aloft, creating a dynamic atmosphere where clouds danced slowly, yet almost imperceptibly.
As the day progressed into midday, the weather transitioned noticeably. Cloud cover decreased to an average of 64%, with low clouds now making up 53% of the sky, while mid-level clouds dropped to just 26.8% and high clouds nearly vanished altogether. The surface winds picked up slightly to an average of 2.6 mph, while winds at 100m gained strength, averaging 3.5 mph. This increase in wind speed at higher altitudes began to shift the clouds, allowing for brief glimpses of blue sky, albeit still dominated by the low cloud layer. The wind dynamics created an interesting visual effect, as the low clouds moved in a more organized fashion beneath the stronger currents aloft, which were now beginning to stir up a bit of turbulence. The interaction between the differing wind speeds and directions at various altitudes created a layering effect in the clouds, producing a somewhat dramatic sky that hinted at more changes to come.
By the evening, the weather began to take on a more overcast character once again, with cloud cover increasing to an average of 91%. Low clouds dominated the scene, now accounting for 90.3% of the total cloud composition, while mid-level clouds hovered around 60.7%. Surface winds increased slightly to an average of 3.6 mph, but winds aloft at 100m reached a higher average of 7.1 mph, enhancing the sheer dynamics of the atmosphere. This strengthening wind aloft created a pronounced wind shear effect, which further complicated the cloud structures and added to the turbulence of the evening sky. The clouds shifted rapidly, with the lower layer trailing behind the faster-moving winds above, creating visually striking layers and a sense of depth against the dimming light. The day concluded with a temperature barely changing to an average of 48.3°F, leaving a lingering impression of a day marked by shifting cloud dynamics and layered skies.
