Pall-Bearing Storm

By

What are the odds?  For the second time in three years, an uncommon August supercell in central Oklahoma was visible...from the same spot.  This storm was bigger, wetter, messier, and more severe, surfing its own outflow, with the main mesocyclone behind the gust front, but still, no less photogenic in its own way.   About the time of this photo, with a clue in the turquoise coloration of the … [Read more...]

Cryptic Left Mover

By

On the way from intercepting the Faith HP hail machine toward intercepting another right-moving hail producer near Rapid City, my own course got intercepted.  This storm formed to the south of the most direct route, evolved into a left-moving, elongated, anticyclonic supercell, and traveled northeastward across the best course.  It also produced a large area of outflow that crippled, but did not … [Read more...]

Great Plains Golden Hour

By

One of my most scenically and photographically rewarding chase trips of 1997 continued down the length of the Oklahoma Panhandle, with the warming of colors in the "golden hour".  The wonderment played itself across an already splendor-splashed sky laden with mammatus and a rainbow, albeit with a different windmill for foreground this go-'round.  The red sunset sky near Slapout would finish the … [Read more...]

Hail Machine’s Hail

By

A severe, heavy-precipitation supercell, of the type storm chasers and spotters often nickname an "HP Hail Machine", dumped a large quantity of significant severe hail west and south of Faith, SD.  From north of Faith, I went south of town and chose that viewing perspective, since the storm already was closing in on the west option.  After it passed off into a relative road void, I broke off to … [Read more...]

HP Hail Machine

By

Experienced storm observers shall take one look at this scene and understand, foremost, that there's probably a lot of hail in there.  Indeed this was a hail factory, the grayish-white mass of rear-flank precipitation surging southeast behind and under that ragged shelf cloud, that core reflecting nearly as much light back to the observer as the cloud itself.  The arcus formed nearly a vertical … [Read more...]

Glaciation

By

Here is the moment when deep towering cumulus (containing cumulus congestus) turns to cumulonimbus: the ice-crystal development known as glaciation.  Sometimes, as here, glaciation occurs when the towers penetrate into pileus clouds that have developed at what will become anvil level.  Within minutes, the icy anvil was fully developed and spreading downshear, away from this vantage.  Periodic … [Read more...]
