Radar operations were not anticipated due to the NSF site visit that was in progress at CSU-CHILL. However, by 1900 MDT a horizontally extensive, dark precipitation "wall" was approaching Burlington CO from the west. In response to this visual observation, the CHILL was brought on the air. The initial PPI scans showed the radar to be at the northern end of a fairly solid line echo pattern that curved south-southwestward to the 150 km range limit. Reflectivities exceeded 50 dBZ only in small patches of the line, and radial velocity magnitudes were not particularly large. Radar operations were continued through about 2130 MDT, when the system had generally weakened into mostly stratiform precipitation.
