Even though this squall line was shallow, it produced enough precipitation to cool the core air considerably, and in translating quickly east-northeastward, forced a good deal of only marginally stabilized air over the top of the cold, dense current of outflow. That process forced a shelf cloud (a type of arcus cloud connected to its parent storm’s cloud mass) to condense, as it all rolled past Rolla and across the verdant North Dakota countryside.
