December 12th, 2025 Timelapse
On December 12th, the day began under a thick blanket of clouds, with an impressive average cloud cover of 99.3%. Low clouds dominated the scene, comprising 97% of the coverage, while high clouds added an additional 91.3% to the overcast sky. Surface winds at 10 meters hovered around a gentle 2.9 mph, with slightly stronger winds at 100 meters reaching 4.6 mph. This light wind at surface level contributed to a tranquil atmosphere, while the higher elevation winds began to create a slight movement in the dense cloud cover. The temperature sat at a cool average of 51.9°F, setting a somber tone for the morning. Despite the lack of precipitation at this juncture, the heavy cloud cover indicated moisture in the atmosphere, hinting at potential rain as the day progressed.
As the day transitioned to midday, the already thick cloud cover managed to increase slightly, averaging 99.5%, with low clouds now accounting for an impressive 99.2% of the total coverage. Surface winds picked up a bit, averaging 4.5 mph, while winds at 100 meters had increased to 6.0 mph. The higher winds began to push the clouds along at a faster pace, creating a dynamic display as the layers shifted and swirled against the still relatively calm surface winds. This contrast led to some minor turbulence, as the wind shear between the lower and upper layers resulted in visually interesting ripples in the cloud formations. A trace of precipitation, measured at 0.01 inches, fell during this period, further emphasizing the humid conditions present in the atmosphere.
By evening, the cloud cover had notably decreased to an average of 59.0%, with low clouds comprising approximately 50.7% of the sky and high clouds falling to 27.7%. Surface winds remained consistent, now averaging 4.8 mph, while winds at 100 meters had increased to 7.9 mph. This continued shift in wind patterns allowed for more layered cloud formations to emerge, as the upper clouds drifted away from the thicker lower layer. The temperature dipped slightly to an average of 53.8°F, providing a cooler end to the day. The sky exhibited an intricate dance of clouds, with some turbulence remaining due to the conflicting wind directions at different altitudes, showcasing a final show of the day’s weather dynamics. The evening concluded with a much more open sky, leaving behind the heavy, moisture-laden clouds that had characterized the morning and midday hours.
