Sticky Stacks

By

A heavy, west, sticky snowfall, coating the north faces of many well-exposed tree trunks, piled up on thin twigs and small branches.  This happened despite the presence of 15-25-mph north winds through much of the event, which normally would both shake and directly blow the snow off.  The limbs shook, but the snow stuck.  This snow was so moist and dense that it fell in large aggregates, and had … [Read more...]

Sunset 99

By

This was somewhere between the 99th sunset I had admired (long ago as a kid) and the 99th I had photographed (not keeping count, but probably sometime in the 2000s).  But it was the first photogenic sunset of 1999, as seen from the roof of the former NSSL/SPC facility on the OU North Campus.   Scuddy fractocumulus rags wafted southward in the cool outflow, produced by the same area of convection … [Read more...]

Slicing the Sunrise Sky

By

A serendipitously symmetric sunrise scene serenaded sight and soul, on this crisp central Oklahoma morning.  Thin, high cirrus and a couple contrails brightly reflected higher light, while altostratus chunks brought warmer-toned hues from lower elevations where the rays had to penetrate more atmosphere.    This was yet another among a growing collection of single-location views from the last … [Read more...]

One-and-Done Cone

By

“Cones” of this sort crisscross Kansas often in most springs.  That included the year of this slide.  The parent supercell formed in a narrow sliver of favorable instability and shear tucked between a dryline, warm front and outflow area, lasted just long enough to produce this tornado in the warm-frontal zone, then…poof, gone:  tornado and supercell alike.  Had there been a dual-polarization … [Read more...]

Ice Machine: Let It Go

By

The beauty of the wildflower-carpeted rolling Great Plains belied the violence of the messy supercell crossing the distance from right to left, at high velocity.  This post-cold-frontal storm moved from north-central Wyoming into southwestern South Dakota and increasing moisture, aiding and abetting a fast-moving, outflow surfing, rotating hail machine, with severe gusts to boot.  The front-flank … [Read more...]

Twin Vault Blast

By

Though similar in brightness, distance and shape, these flashes aren't identical, so we'll call them fraternal twins.  By the time we arrived at this vantage to shoot lightning, what had been a skinny, poorly organized, young supercell at sunset had latched onto the low-level jet and its associated high-helicity inflow layer.  That fattened the storm a great deal and made it destructively severe, … [Read more...]
