This storm formed over the Sangre de Cristos west of Trinidad, and was a well-developed supercell by the time it passed over town. By the time of this photo, east of Trinidad, the supercell had enlarged and clearly strengthened, sporting a very large updraft base, multiple tail clouds, and intermittent wall clouds. Entering richer moisture, the storm would intensify further, lower its based to … [Read more...]
Felt Mammatus
The title has a simple meaning that is not obvious to those unfamiliar with southern High Plains geography. No, this wonderful sunset scene wasn't "felt" as a feeling, at least not physically nor emotionally, nor did I judge its apparent texture as resembling the fabric known as felt. I suppose one can get deliriously artistic, especially with aid of mind-altering substances, and dive into those … [Read more...]
Morning after Downburst Hail
Pieces of trees litter a camping/picnic pad the morning after an intense downburst struck Ord, containing measured severe gusts and marginally severe hail. The wind-driven hailstones shredded vegetation, including leaves and adjoining twigs in overhead trees. Though such effects are common after hailstorms, it's uncommon to see them the next morning basically as deposited, without being removed … [Read more...]
Shelfie Six Pack: Dark Back

I deeply, innately enjoy this kind of ominous light on land and in the sky. The base was related to unseen convective towers getting very deep … [Read more...]
Shelfie Six Pack: Flying Formation
[Part 5 of 6] Following the fascinating interplay of light and shadow and illusions offered by a passing shelf cloud in the dim early twilight, this odd formation rose on a localized plume of lift, hoisting the underside of the arcus cloud material in its path along a sort of bow wave. This feature sailed swiftly southward (left to right) across the sky, and diffused itself within another minute … [Read more...]
Shelfie Six Pack: The Shadow
[Part 4 of 6] After photographically masquerading as a tornado, a morning blue-hour shelf cloud zoomed past, casting a strong shadow in the dim early light, twilight exaggerating the difference in brightness across its edge. Though seldom seen because I'm usually asleep or at work at this hour, morning pre-sunrise arcus formations can produce one of my very favorite lighting effects in all the … [Read more...]
