STORM / DRAMA
Fast-Moving Cloudscapes
Fast wind aloft drags textured cloud across a long exposure.
How it works
Fast wind high up drags textured cloud across the sky. In a long exposure that motion smears into dramatic streaks over a still landscape. Bring a tripod and a neutral-density filter.
What to check in the field
This is a Watch look: the ingredients are forecastable, but whether the wind aloft matches the surface reading — the point forecast cannot see cloud speed at altitude, and structured broken cloud is a matter of convective luck. Shotcast flags it so you know to go and look.
