An arcus cloud with your morning coffee? Thunderstorms to the north sent a cold pool of outflow rushing outward to force up a nocturnally cooled near-surface layer of air, rendering this beautiful formation to start the day. The outflow at the surface extended miles past the shelf cloud, as evident in the stiff breeze whipping the flags, and revealing the shallow slope of the whole stable-layer lifting mechanism. This action also yielded lenticular clouds above the shelf, when seen head-on.
