Heading east across the High Plains yesterday, my pickup was buffeted by strong, south winds from Goodland, Kansas, to Hays. Since the air was warm and dry, no clouds raced across the deep, blue sky and I could not readily explain the cause of the intense wind.
This morning, as I continued eastward, those potent winds were still blowing and strands of clouds appeared overhead, all pointing toward the northeast. These strands thickened and darkened as I entered more eastern regions of the Great Plains, indicating that Gulf of Mexico moisture was being drawn northward by the wind.
Then, as the highway climbed atop the Flint Hills of eastern Kansas, broad views unfolded to the north revealing dark skies that stretched across the horizon, topped by towering cumulonimbus clouds. This was the heart of the pinwheel-like storm, beneath which heavy rain and probable hail were pelting the ground. Quite a spectacle from a safe distance.
