High Plains High Voltage

By

Funny it is, how often we frequent storm observers end up in some of the same places as before, hundreds of miles from home.  Two years and four days prior, I photographed a sunset at the same pullout.   This time, it made a great vantage for a few minutes of attempts to shoot bright, daytime lightning from a former supercell that was evolving into a small bow.   Unlike an even older, more-distant … [Read more...]

Sucking Dust on the Great Plains

By

Stunning in form on its own, this supercell north of Kit Carson sported a vast field of mammatus across the underside of the downshear anvil, near to far.  Meanwhile, a wall cloud under the right base, and arcus cloud under the left, could be seen clearly, despite all the intervening blowing dust.  Displacement of dust, sand and soil by wind is called an eolian process in geology.  This counts!  … [Read more...]

Plated Sky

By

An expansive, late-stage supercell strutted insistently across the Great Plains’ vast stage with one final, gaudy show, before getting absorbed in a broader band of thunderstorms.  Dust rising into the wall cloud at lower middle showed the storm still had a surface-based updraft, though the cloud plates represented stable layers through which the storm’s rotating chimney of low pressure also was … [Read more...]

Colorado Prairie Fire

By

Ignited by an exceptionally potent lightning strike under a supercell's anvil, this Great Plains grass fire spread out in a ring at first, then got steered westward by strengthening inflow to the storm that caused it.  Sparse, light rain falling from the anvil wasn't enough to stop this conflagration, and fire trucks already were on the way from the nearest towns about 20 miles away.  I exited the … [Read more...]

Pretornadic Wall Cloud and Separate Cone

By

Here we see the early stages of a cone tornado (right), and a rainy "bear's cage" wall cloud from a separate mesocyclone (left), bracketing a CG strike from the main core, all in the same large and complex supercell.  Observation of the wall cloud in lightning and Union City town lights revealed that it was rotating.  Meanwhile, as the cone moved away to the northeast, toward an area just west of … [Read more...]

Classic Early-Stage Supercell

By

Seldom does a supercell look more like the classical textbook depiction than this.  One clearly can see the wide updraft base across the lower middle (with small wall cloud), forward-flank core behind the trees at right, flanking line and tilted towers in the left middle half, an "inflow tail" spreading anvil above, and even overturning "knuckles" between the top of the flanking towers and anvil.  … [Read more...]
