Diving south-southeast across the High Plains of eastern Colorado, a magnificent summertime supercell flung large sparks all around, lighting up the night naturally with pulsating brilliance. Though fundamentally similar to other supercells, every one has its own expressive personality in both cloud form and lightning production, unique as a fingerprint. That’s why I appreciate them so, and seek them with the fervor of any big-game hunter. This one was no introvert. For a couple of hours, mostly after sunset, the storm posed for dozens of diversely illuminated photos, a few more of which may become future Images of the Week.
