The fall 2020 ice storm didn't produce large amounts, but instead, caused its havoc by loading small thicknesses on still-leafed, often still-green trees, such as this. The net effect was the same as four times the ice load, or more, during true winter. Here, a crazy variant of ice accumulation occurred when the initial covering of the leaf slid nearly all the way off, but stopped, having been … [Read more...]
Twin Mesocyclones
Two rotating wall clouds revealed twin low-level mesocyclones on the southwest side of a classic, cyclic supercell. The broad one to the left had been rotating, sometimes rapidly, for nearly an hour (without producing any known tornadoes). The one on the right formed on a storm-scale occlusion triple-point northeast of the original; it lasted another 30-45 minutes and yielded only a funnel. That … [Read more...]
Wet Mesocyclone
A supercell that had exhibited a messy but photogenic structure near Noble proceeded east-southeast with a wide wall cloud sporting several tails, as seen here from the southwest. The area was only slowly rotating, thinly wrapped in veils of "atomized" (small-drop) rain, never a serious danger to spawn a tornado, but had to be watched for any sudden tightening regardless. The chase soon ended … [Read more...]
Sunset at Key West
...as seen in this Ektachrome slide taken from the famous Mallory Square area. Reflections off the water and the extensive high cloud deck colored even the normally silhouetted east sides of the low cloud elements, and cast a more uniform orangeness over the whole scene. This was my first Key West sunset; and I hereby confirm that great things can await the photographer at the last place on US … [Read more...]
Electric Green Sky
After an intense, very cold outflow surge heaved past us, more severe thunderstorms developed along it, just southwest of here. The cloud line in the lower-middle and right of this image was an arcus cloud along that outflow boundary. The thunderstorm became rooted in an elevated unstable layer as the boundary continued SW, but kept spewing cloud-to-ground strokes through the cold air. Yes, it … [Read more...]
Oregon Coast Stratus
A fixture of the Pacific Northwest, misty stratus enshrouds the basalt cliffs and cape-capping meadows of coastal Oregon. Stratus and fog often form over the cold California Current offshore, then move onshore and upslope in westerlies. The cool, moist air ascends the Coast Ranges, further clouding the scenery just inland. Lewis and Clark probably reached no further in their expedition than … [Read more...]
