Strobing with dazzling frequency, electrical strands and filaments flashed atop a supercell's rear-flank gust front, both silhouetting and illuminating its laminar shelf cloud. I took several shots of such discharges in just a few minutes, and could have captured many more but for an area of spotting priority off to the right. The tornado-warned storm supposedly produced one about 10 minutes … [Read more...]
Minnesota? Florida? No…Norman!
Crickets chirp by the hundreds, a chorus of bullfrogs chants the day to a close, and an occasional fish splash is heard somewhere across the glassy waters of this little lake in the woods. This is Norman, Oklahoma? Yes! [Chamber of Commerce, please call...] Urban parks like this can be a great place for peaceful, romantic sunsets. Norman OK (Jun 98) Looking WNW 35.2429, -97.4281 … [Read more...]
A Superior Beach
Bright tan-orange sand (from nearby outcrops of Precambrian Jacobsville sandstone) contrasted nicely with the clean blue waters of Lake Superior, and a soft blue sky brushed by streets of stratus. The morning had dawned cool and overcast. This hole in the stratus deck formed in late morning and expanded throughout midday, as solar heating and boundary-layer mixing over land—some of which … [Read more...]
Dover Duster
The early-stage Dover tornado began to organize better, whipping up a frothy column of slightly wettened dust as it crossed a plowed field where light to moderate rain had fallen briefly. The bottom of the young vortex twirled slightly more than a mile away at this time, faintly audible as a distant waterfall noise, located to the southwest yet zipping along mostly eastward. In this strongly … [Read more...]
Painted Mackinaw Sky
Just after sunset, the deepening blue sky and some high, rosy cirrus painted serene summer scene above the Straits of Mackinac. Even in a a benign weather situation, the sky still can change dramatically after a few short minutes, and with the aid of a swap of lenses, can provide a strikingly different look in a subset of the same scene. Mackinaw City MI (17 Jul 7) Looking NNW 45.788, -84.7294 … [Read more...]
Early-Stage Cone and Satellite Funnel
A well-structured, autumnal supercell developed a strong area of spin in the lowest part of its updraft area, which gradually intensified into a tornado as it moved closer. This was in the first several seconds of the confirmed tornado, with rotating dust beneath. That wasn't all; I almost had a satellite tornado spin up even closer! The funnel at right rotated briefly but tightly. I watched … [Read more...]
