June 21st, 2026 Timelapse
On June 21st, the morning began under a blanket of clouds that covered approximately 71.2% of the sky, primarily comprised of low clouds at 61.8%. Surface winds were gentle, averaging around 2.7 mph, while at 100 meters, winds picked up slightly to 3.7 mph. The low cloud layer moved slowly, influenced by the light winds below, resulting in a somewhat muted start to the day. The temperature hovered around a cool 56.1°F, and there was no precipitation, allowing the clouds to remain intact without any rain. With such light winds, there was little turbulence or conflict between wind layers, creating a stable atmosphere that set the stage for later dynamic changes.
As the day progressed toward midday, conditions evolved significantly. The cloud cover dramatically decreased to just 20%, with low clouds making up the entirety of that percentage but dissipating steadily. Winds at the surface rose to an average of 5.0 mph, while winds at 100 meters increased to 6.6 mph, creating a gentle breeze that nudged the remaining clouds along. The increase in wind speed contributed to a clearer sky, as the higher winds helped to push the clouds out of the area. This elevation in wind speed also created a mild wind shear effect, though turbulence remained minimal due to the consistent direction of the surface winds. Temperatures climbed to a pleasant 69.3°F, signaling a warm afternoon ahead.
By evening, the transformation was complete, with the sky clearing to a remarkable 0% cloud cover. Surface winds increased further to an average of 8.5 mph, and winds aloft reached 12.0 mph, enhancing the overall stability of the atmosphere. With the absence of clouds, the sun’s warmth became more pronounced, bringing temperatures up to a comfortable 72.9°F. The evening light revealed a completely blue sky, with no sign of the cloud cover that had dominated earlier in the day. The winds at various altitudes, while generally steady, maintained their direction without significant turbulence, allowing for a calm and picturesque conclusion to the June 21st weather.
