This menacing-looking, borderline classic/HP supercell in southern Oklahoma formed along a progressive, southeastward-moving outflow boundary, but kept up with it, thereby maintaining warm-sector inflow. The updraft was large, elongated, deep and rife with areas of cyclonic shear, and intermittently but briefly strong rotation all along the large wall cloud. Our best view of it during the most … [Read more...]
Fallen Assortment
A heavy-precipitation supercell formed near a warm-front/dryline triple point and rampaged east-southeastward for several hours just north of the front, a storm of the sort I informally call "ice machines" and "north Texas stormzillas" for obvious reasons. This supercell laid down a historic swath of severe to giant hail, never to be forgotten by all who observed it first-hand. I got in its path … [Read more...]
Montana Mothership
Most folks who started out northbound on I-25 or westbound on I-90, hours before, weren't expecting to find this hovering over the combined road along their journey into southern Montana! Indeed, both before and after I darted up an embankment to shoot this safely from the median, a few people pulled off the exit ramp and asked me if they should drive onward, to which I responded, "Not for … [Read more...]
Butt Cloud
No, this isn't about the noxious clouds from a butt, but instead a cloud resembling one! Clouds can take on many fascinating, lifelike shapes. The double-cheeked mammatus protrusion at middle right, conveniently spotlit by a ray of sunset, so strongly mimicked the shape of a human posterior that I just had to take its picture. Mammatus clouds, of course, are named (via a Latin root) after … [Read more...]
Retreating Mammatus over the National Weather Center
Spreading northwestward from momentum faster than the upper level flow could offset, the collective anvil shield of a few supercells spread over the area, decorated with mammatus pouches. By this time, the entire complex had begun retreating away, the mammatus field still reflecting the muted twilight glow of a western sky tinted by the hidden sun. In the distance, a well-timed, cloud-to-ground … [Read more...]
Popping a Mountainside
On this first evening of monsoon storms in southern Arizona, I didn't have much luck remotely shooting lightning amidst reddening sunset light from a western core. So, after seeing a bright flash behind me, reflected off the inside of the car where I was sheltering, I got out quickly and turned things around. Not much lightning happened this direction in-frame, but what did occur was a doozy. … [Read more...]
