This is a classical and well defined precipitation core, punctuating the skies above the beautiful High Plains wheat fields of eastern Colorado. Distinct shafts of rain and/or hail, such as the one just off the left side of the main core, sometimes are mistaken for tornadoes by the inexperienced spotter, but the sure clues include a lack of rotation. The large thunderstorm responsible for this deluge had intermittent evidence of weak rotation, but mainly was a multicell until around sunset. After it merged with a few more recently developed cells into a thunderstorm complex, a small bow echo evolved with a ssectacular sunset and lightning display on the back side.
