Outflow is supposed to be the ultimate enemy of the storm chaser, but it can be quite beautiful! Here, the turbulent underside of an arcus cloud passes over the Wichita Mountains of southwest Oklahoma, with the precipitation core of a squall line visible in the background. The bright green fields of early May and the taupe-toned, partly scrub-covered Cambrian granite of the worn-out old mountains contrast nicely with the roiling slate blue underbelly of the arcus, in this slide from decades ago.
