The setup on this day supported another summer day with possible flash flooding over and near the mountains, though the setup did also support severe thunderstorm development as the activity pushed off the mountains into a more unstable air over the plains. This indeed did occur, with flash flooding and severe storms being observed from the Upper Arkansas River Valley down along the Highway 50 corridor and into the Pueblo area.
