A collection of storms in the west through north aggregated their outflow in a short time period, sending a deep but mostly dry gust front sweeping down the plains of south-central Nebraska. A little of the dust kicked up by the gust front is visible just above ground level, and deeper atop the cold pool, delicate strands and wisps of fractocumulus waft across the scene. Because the sky already was dark outside, this is only a slight underexposure to accentuate the texturing of the scud filaments against the bright anvil from those storms.
