Description:During the fall and spring months the weather in eastern Colorado often produces a mixed bag of precipitation. The radar observer must deal with thunderstorms, widespread rain and rain showers, and snow all at the same time. Unlike the random convection of summer, these thunderstorms are generally associated with vigorous cold fronts which are followed by upslope and overrunning conditions which produce widespread rain and snow. The thunderstorms and snow are generally straightforward as far as their display on the radar, but the transition zone between solid and liquid precipitation can cause serious interpretation problems far the radar observer. This is because erroneous DVIP levels can be caused by melting precipitation near the ground. It is the radar observer's job to understand the meteorological processes taking place and to determine if DVIP levels on the PPI are erroneous.
