LeFors Revisited

By

This wide-angle view of a very wet, classic supercell shows a wall cloud at lower middle, smooth accessory base above, tail cloud extending to the right, and a dense precipitation core to its rear.  That rear area later would drop huge hail around 4 inches in diameter on some other chasers.  Rapid rotation in the lower center portion teased tornadic potential; but outflow soon undercut the … [Read more...]

Prairie Flickering

By

The campsite was claimed, the vehicle serving as a rigid tent that was safe within from the coming source of lightning.   It was time to admire and shoot this marvelous little light generator in the prairie twilight, with the Badlands at my back.  This convection was elevated above a boundary layer stabilized by earlier storms.  A scud cigar evolved into a roll cloud, surfing outflow upon outflow, … [Read more...]

Channels of Charge

By

A high-based, nighttime thunderstorm offered numerous blasts of electricity for my viewing pleasure, including this one that lit up both convective towers above and miles of cloud beneath.  Obviously, the main channel of electric current here is the one through which the return stroke rushes upward, brilliantly illuminating the downward zigzag of the successful step leader.  [The step leaders are … [Read more...]

Bellaire’s Barely Tornado

By

After the McLellan Lake tornado of 20 May 99, I didn't expect to see another obviously closed, ground-contacting vortex that could compete for the ignominious title of "weakest tornado I've seen".  This was that.  Under a broadly rotating, seemingly modest mesocycloic notch in this storm's updraft area, scud began to rise and turn slowly, right up from ground level, gradually condensing into a … [Read more...]

Stockton Tornado and RFD Cut

By

A classic Kansas tornado developed from a supercell we watched from the very first dryline towers, until nearly simultaneous supercell and tornado dissipation north of the warm front.  The bright, relatively clear area above-left of the tornado, allowing more-direct sunlight through, was a cloud gap cut by the inner part of the rear-flank downdraft wrapping around the mesocyclone and supporting … [Read more...]

Bark Snow

By

Clumps of wet snow stuck to outreaching areas of bark on the north sides of trees during central Oklahoma's New Years Day 2021 snow event.  The high-adhesion, wet aggregates decorated those outer windward surfaces, while the moss that also festooned the north sides (albeit less ephemerally) provides the green in the trenches. Norman OK (1 Jan 21) Looking SSW … [Read more...]
