Twilight Sparker

By

Despite its being worn down to a high-based, skeletal nub by dry entrainment and stable-air ingestion, the remains of what had been a vigorous little Colorado High Plains supercell continued to shoot cloud-to-air lightning every few minutes.  Here, I was fortunate enough to catch one discharge and the faint ending part of another, with the shutter open on a brief time exposure. 5 ESE Boyero CO … [Read more...]

A Supercell’s Evening Pastels

By

The 30-hour period beginning around 3 p.m. on this day offered two extraordinary storm-chase adventures in the same corridor east-northeast of the Denver metro area and south of I-76—including the next day's Prospect Valley tornado.  This was the fifth of six late-afternoon to evening supercells, and perhaps the most consistently spectacular, in a protracted train of storms rolling out of the … [Read more...]

Annular Eclipse

By

Solar eclipses can be viewed with the eye and photographed with an unfiltered camera, but only near sunrise or sunset, no differently than the non-eclipsed sun.  For that reason, the unobstructed view on the High Plains, and its proximity just a few hours from home, the choice of the sunset segment of the 2012 annular eclipse track was obvious.  The only question was cloud cover, which evaporated … [Read more...]

Big Dome

By

This storm just had erupted within the previous hour along an old outflow boundary.  Shortly before sunset, it was becoming a supercell at the time it thrust this massive overshooting dome well into the stratosphere.  The supercell had a deep, persistent mesocyclone, but only yielded reports of heavy rain and hail up to the size of golf balls.  Still, its brightly lit form, with secondary anvil … [Read more...]

Tornadic Supercell, Wyoming High Plains

By

By this time, the Chugwater tornado clearly was beginning to meet its Chugwaterloo.  Though moving toward us in an absolute sense, it had migrated toward the back of the storm in this wide-angle view, while a new (and ultimately non-tornadic) mesocyclone formed in front middle, with a thin, broken tail cloud to its right.  The tornado had wrapped so much rear-flank and occlusion-downdraft air that … [Read more...]
