September 30th, 2026 Timelapse
On September 30th, conditions began with a gentle start as the morning unfolded. Surface winds were calm, averaging just 2.6 mph, while winds at 100 meters climbed slightly to 3.7 mph, creating a subtle breeze primarily out of the east. This low-level stability allowed for a solid ceiling of clouds, with cloud cover at around 65.8%, predominantly composed of low clouds that constituted 57.8% of the coverage. The temperature was a cool 53.0°F, lingering in the air as a hint of moisture was present, with a trace amount of 0.03 inches of precipitation likely resulting from the overcast skies. The varying wind directions at different altitudes—especially the notable 47° divergence between surface and 100-meter winds—introduced a light turbulence, stirring the lower cloud layers and adding a dynamic texture to the morning sky.
As the day progressed into midday, the weather underwent a noticeable transformation. Winds began to pick up, with surface speeds increasing to 4.3 mph and those aloft at 100 meters reaching 5.7 mph. This rise in wind strength coincided with a dramatic shift in cloud cover, which diminished to an average of 33.2%. The low cloud layer began to dissipate, leaving only a scattering of high clouds rising to 33% coverage. The winds, now having a more uniform direction, facilitated a faster movement of the higher cloud layer, allowing for a more dynamic sky. This resulted in the high clouds streaking across the backdrop, pulling away from the previous morning's stillness. The slight increase in temperature to 61.8°F provided a warm contrast to the previous chill, while the enhanced wind shear between the surface and aloft levels continued to influence the cloud movement, creating a layered visual effect above.
By evening, conditions shifted once again, reflecting a more mixed atmosphere. Surface winds increased slightly to an average of 5.3 mph, while winds at 100 meters escalated to 9.3 mph, indicating a more robust presence of wind at higher altitudes. The cloud cover surged back to 71.6%, predominantly composed of high clouds which dominated the skyline. The layering of clouds became more pronounced as the differing wind patterns continued to interact, resulting in a visually striking scene where the high clouds moved with agility against the slower surface winds. The evening's temperature settled at 62.9°F, with the lingering moisture in the sky hinting at the possibility of further precipitation. The turbulence caused by the interaction of varying wind directions at different altitudes added an intricate dance to the cloud formations, transforming the evening sky into a vivid display of nature’s dynamism.
