Unplanned more than a few minutes in advance, therefore greatly appreciated, this remarkable scene greeted me on the front side of a band of thunderstorms rolling into Oklahoma City. I had been returning from a two-day chase trip to southeastern Kansas, just trying to beat the rain home on day three. Rounding the corner of I-35 and I-40 east of downtown OKC, I gazed straight into some of my … [Read more...]
Supercellular Hues
Late sunset light filtered differently through a dense rear-flank core, accessory arcus, nearly laminar updraft cloud, and anvil material aloft, offering a naturally painted storm scene unique to a few minutes of this time of evening. Even a messy supercell like this can offer moments of beauty and appreciation—albeit brief and measured, when the storm is moving quickly toward the … [Read more...]
Flashes Flung Far
Tendrils of cloud-to-cloud, in-cloud and cloud-to-air lightning flew every which way around the upper reaches of an evening supercell, whose main updraft column tilts from lower left to middle. Had this storm been tornadic, I might have regretted my choice to back off for enough distance to capture more of the phenomenal light show. Maybe! Fortunately, it was not, and the supercell it provided … [Read more...]
Oncoming HP Load
Heavy-precipitation (HP) supercells can take many forms (most of them rather menacing in appearance): behind big arcus clouds, drum-shaped, deep and dense with great structure, spiraling in form with wrapping tail and wall clouds, with an embedded little tornado visible, with an embedded big tornado visible, with a tornado playing hide and seek and sometimes a peek, pastel-festooned in the sunset … [Read more...]
No Grace for Gracemont
Here was a peculiar combination of a truly hybrid shelf and wall cloud that couldn't decide which it wanted to be. A tremendous precipitation surge had descended through the back side of the supercell, then started to wrap through the southwest side of the low-level mesocyclone, accelerating the storm but not completely undercutting the original low-level circulation, whose cloud material still … [Read more...]
Dumont Dust Tube
The "Dumont" tornado seldom, if ever, had a condensation funnel, but it lasted ten minutes while gradually lofting dust toward the rotating, scuddy cloud base above. I was unsurprised and glad to learn that this vortex produced no known damage, in a sparsely populated area of large ranches and few structures. Despite dozens of chases and even more supercells seen in these parts, the vast area … [Read more...]
