Shelf Cloud Rolling Over Singapore Prairie at Dusk

A massive, dark gray shelf cloud stretches horizontally across the twilight sky, its undulating underside hovering just above the flat prairie. The wet season air hangs heavy, allowing ground fog to pool in the low depressions of the grassland. Behind the rolling storm front, a distant layer of stacked thunderheads rises against the fading light. The horizon glows with the warm, orange hue of Kampong Glam town lights, against the cool blue tones of the approaching weather. The flat terrain offers an unobstructed view of the cloud's smooth, curtain-like texture as it advances. A faint shadow from the cloud edge falls across the nearest patch of tall, damp grass.
