Marfa Light
After forming in Old Mexico, this supercell crossed the Rio Grande, became elevated atop outflow that had spilled over the Davis Mountains from storms around Marathon, and yet forged onward in a merry parade of light and striking cloud forms. Here the storm crosses the mountains NE of Marfa, casting a beautiful back-glow across a landscape stroked by a ribbon of ground fog, and brightening our entire evening in the process. A zoom view several minutes later revealed a grand micro-scene of land and sky.
