The Day the Sky Glowed Over Big Bear 🏔️✨
On February 20, 2026, an awe-inspiring sight took over the horizon at Big Bear Lake, CA: a massive, "glowing wall of clouds" surging over the mountains during a powerful winter storm.
The Science Behind the Glow This dramatic display is a masterclass in atmospheric optics and storm dynamics:
The "Wall" (Shelf Clouds): As a cold front moves in, cold air pushes warmer air upward, creating a distinct, low-hanging horizontal cloud known as a shelf cloud. These clouds are dense with moisture and ice, forming a sharp, physical "wall" against the horizon.
The "Glow": The fiery orange and gold colors are the result of back-scattering. During the golden hour, the sun sits at a low angle, hitting the high-density water droplets and ice crystals from behind. This illuminates the storm front, making it appear as though it is burning from within.
The Contrast: The deep blue of the lake and the fresh white snow on the soil (from the 8 inches that fell that day!) intensified the warm colors of the sky, making the glow appear even more vibrant.
Nature’s power and beauty on full display!
