June 30th, 2026 Timelapse
On June 30th, the day began with a thick blanket of low clouds enveloping the area, resulting in an impressive 94.5% cloud cover. The surface winds, averaging 7.3 mph, were relatively gentle, while winds at 100 meters above ground were notably stronger at 11.1 mph, creating a significant contrast that hinted at some atmospheric turbulence. This difference in wind speeds likely contributed to the dynamic cloud movements observed, with the low clouds shuffling slowly across the sky. Temperatures hovered around a cool 53.8°F, and despite the heavy cloud cover, no precipitation was recorded, suggesting that while the clouds were present, they were not saturated enough to release rain.
As the day progressed towards midday, cloud cover intensified to a full 100%, maintaining that persistent grayness over the landscape. The surface wind speeds picked up slightly to an average of 8.8 mph, while winds aloft increased to 12.3 mph, further enhancing the overall stability of the atmospheric conditions. This shift in wind dynamics resulted in a continuous flow of low clouds across the sky, which were pushed along by the stronger upper-level winds. However, with all cloud layers remaining low and devoid of mid or high cloud formations, the skies lacked the typical layered look seen with more complex systems. The absence of precipitation continued, highlighting that the clouds, while dense, were primarily composed of moisture without any active rainfall.
In the evening, conditions began to change as cloud cover decreased to 74.5%, allowing glimpses of the sky to emerge. The wind at the surface increased further to an average of 10.1 mph, while the winds at 100 meters rose to 14.4 mph, reinforcing the earlier trend of stronger winds aloft. This change in wind patterns resulted in a more dynamic sky, with the remaining low clouds shifting and breaking apart. The slight presence of higher clouds at 5.3% added a new layer to the atmosphere, indicating a gradual transition as the day waned. The combination of different wind speeds created areas of turbulence, showcasing an interesting conflict between the layers that contributed to the evolving cloud dynamics visible through the evening. Overall, the day exhibited a fascinating interplay between wind, cloud cover, and atmospheric stability, culminating in a rich display of Northwest skyscapes.
