This storm probably never had much chance to be sharply sculpted; it was too turbulent and rotating too fast! For about half an hour, what had been a rather nondescript, high-based, marginal supercell began to spin furiously and turned sharply southeastward in classical right-moving fashion. Ragged cloud material whipped rapidly around an intense low level circulation that was tornadic at … [Read more...]
Geothermal Ephemerality
Hot springs all across Yellowstone National Park, including here in the Norris Geyser Basin, exude odd hues, thanks to combinations of heat-loving aquatic bacteria and both suspended and precipitated minerals. The result is a nearly endless variety of abstract forms of tint and texture, especially at the level of zooms into parts of a given spring's pool. These shapes and colors change over … [Read more...]
Rusty Pelicans
Vintage, rust-encrusted metal pilings from the 19th century obviously serve as popular perches for pelicans in the Dry Tortugas. There, safe places to rest above ground, within sight of food fish, and away from the reach of people, are not common. I didn't notice this scene until playing with zoom settings, scanning left and right, when a composition that I found immediately unique and … [Read more...]

Stroke of Brilliance
A tremendous two-channeled strike brightly illuminated land, sky and water near the north end of Lake Murray. While a dazzling and spectacular display for the lightning photographer, this is not what any given fisherman wishes to see while cruising his bass boat across the water. Fortunately, a different severe storm already had come and gone very recently, clearing all nautical traffic off the … [Read more...]
Bad Storm Coming
After merging with some other convection, the broader, messier but only weakly tornadic version of the El Reno supercell presents an unusually dark, ominous face while looming beyond the National Weather Center. There I took a very brief break from outlook and forecast-support duties to spot the incoming storm, take this photo, and assess its potential to produce a tornado close enough for backup … [Read more...]
