Just a simple multicell storm this was, with an outsized capacity to fire high-amperage jolts for great distances in several directions! I called this the "7-11 Lightning" series because that was the date, and also because I took a really "big gulp" when seeing this awesome blast of electricity flung miles outward from the little storm that created it.

Cirrocumulus over Camelback
On a dry, cool winter day, high astride Camelback Mountain, cirrocumuli wafted over a palo verde tree growing hardily out of a soiled notch in Precambrian granite. This scene made a great excuse to sit back against a boulder, relax for a spell, and watch the sky, on the otherwise strenuous hike. Phoenix, AZ (8 Jan 15) Looking N 33.5144, -111.9605 … [Read more...]
Slapout Sunset
What can be a more fulfilling finish for a long journey to, under, around and through violent thunderstorms than a fiery Great Plains sunset? This was not a high-priority "chase day" for most storm enthusiasts, being well after the peak of the season; and the few who made it out went after some messy heavy-precip (HP) severe storms 150 miles farther E along the Kansas/Oklahoma border. But when … [Read more...]
Thunderless Mammatus
Sometimes mammatus clouds don't arise from a thunderstorm. In this case, a dense chunk of cirrostratus clouds developed pronounced bags of mammati, probably with internal motions and processes similar to those in thunderstorm anvils (which also are thick cirrostratus plumes). The technical name for mammatus clouds associated with a thunderstorm is cumulonimbus mammatus; so for consistency this … [Read more...]
Sunflower from Flood Wash
At some point fairly recent to this shot, a sheet of floodwater rushed across these flatlands from the eroding arroyos, pinnacles and bluffs of Badlands National Park. The torrent was strong enough from right to left to flatten grass, and to keep it pinned down with clay deposits before new growth occurred. Brief but intense deluges of rain are the main sculptors of this harsh but photogenic … [Read more...]
Northern Borderland Squall Line
Bringing replenishing rains to the many lakes of the "Turtle Mountains"—the wooded terrain rise visible at distant right—a band of low-topped storms churned ever closer. At this point, the tip of the arcus cloud passed due S of us, offering a fine compositional symmetry with the curvature of the roadway. This is very nearly the farthest north one can intercept a storm in the continental United … [Read more...]
