A weird storm sky flashed before us in deepening twilight. A large, late-developing supercell's main updraft area and shallow wall cloud (lower middle) spun decently but never tightened to tornadic strength, while in-cloud and in-core lightning flashes faintly illuminated the cloudscape from within. Meanwhile, what was left of high-level sunset color somehow found its way down through the dense, … [Read more...]
High Plains Sunrise, Clayton
On the way back from a conference and post-meeting mountain exploration, we awoke on the outskirts of Clayton to a fine sunrise, also revealed in the western (opposite) sky this time. Midlevel convection produced anvil material festooned with small mammatus formations (yet another example of "thunderless mammatus"). Texas and Oklahoma drivers starting the day here or in Dalhart, and headed to … [Read more...]
Southern Kansas Stormzilla
Though north Texas seems to be the hotbed for big, dark, dense, heavy-precip "stormzilla" supercells, you can find them elsewhere on the Plains too, including southern Kansas. They have a menacing beauty all their own, but for conscientious observers, such a storm mostly is a nasty, low-reward/large-risk mess. True to form, the "Potwin HP" churned along, accelerated by its own massive load of … [Read more...]
Desert Mountain Flashes
From the thunderstorm where there was just one flash, came two more. Hence, the admittedly and unashamedly unimaginative two-letter addition to the title of this follow-up! Evening travels southwest of Tucson yielded only weak, small thunderstorms, but they did spit some sparks to make the day's journey worthwhile, and truly appreciated. Foreground plants whipped back and forth in outflow … [Read more...]
Wind-Broken-Tree-Broken Tree
In Acadia National Park, a gust uprooted a mature tree that had a small, shallow root ball, as many do in a wet climate and soft soil. That alone is not too remarkable, nor is it that the tree fell across a smaller one and broke it. [In this website, you may find a huge, tree-busting branch fall from an ice storm in Oklahoma, and general mass treefall from a gradient-wind event in the Olympic … [Read more...]
Autumn Rapids on Joes Brook
A rainy day bolstered the flow of a Vermont creek, pushing good flow over shallow ledges of metamorphic rock, and making a soothing sight and sound from the dry shelter of the late-1800s Greenbanks Hollow Covered Bridge. Hey, if you're going to do photography in the rain, why not be under a roof? Lower light levels under the overcast conditions allow longer exposures and better feathering of … [Read more...]
