Above a deep desert wash in southeastern Utah, a cumulonimbus' anvil spread eastward, blocking out a great deal of sunshine, but for a thin patch allowing the sun itself. Despite the anvil's thickness otherwise, the storm that produced it wouldn't offer a valley-deepening flash flood here; it already was weakening, and soon would devolve to a patch of remnant high clouds wafting toward the … [Read more...]
Autumn Along Swift Creek
Aptly named Swift Creek rushes through its namesake canyon in the Salt River Range, draining a small part of western Wyoming's high country, rendering a beautiful, placid scene with its gaudy clothing of autumnal colors. Off the well-trodden tourism paths, but still readily accessible by road and foot, still reside some gems of the West. This area certainly is one. 3 ENE Afton WY (22 Sep 13) … [Read more...]
Whirling past Wapanucka, Part 4
[Part 4 of 4] There's a lot to unpack and interpret here. After narrowing and becoming a fuzzy, barely condensed vortex, the Wapanucka (Bromide) tornado approached closer, compelling my moving to the next hilltop south, where a safe pullout was available. The tornado narrowed further, but formed a clearly defined condensation cone above the ground. The circulation's base struck a … [Read more...]
LP Supercell in the Golden Hour
A brilliantly sunlit low-precipitation (LP) supercell formed to our north and cruised east-northeastward, up the Turner Turnpike toward Tulsa. The storm put on quite a gaudy show with its flared base, corkscrew appearance to the main updraft tower and ice-crystal collar in the middle levels. Very little precipitation fell from this supercell for most of its early lifespan, except for severe hail … [Read more...]
Whirling past Wapanucka, Part 3
[Part 3 of 4] The Wapanucka (Bromide) tornado apparently narrowed and weakened as it approached, but roared louder, and still was potentially dangerous. Even though I was in a good photo spot, the tornado still was moving toward me. It was time to scoot out of the way. Though not looking as large as earlier, the true size of a tornadic vortex is hard to gauge when condensation is thin and … [Read more...]
LP Supercell and Radome
A near-sunset, low-precipitation (LP) supercell shined in the northeastern sky, with an experimental NEXRAD radar dome I had employed in another favorite image, but shot from the roof of the former NSSL/SPC building. I scanned this wide-angle slide at high resolution and cropped it into an effective panoramic. That backshearing collar of ice-crystal clouds below its top, at a decidedly lower … [Read more...]
