WSR-88d Example Products

Base reflectivity data is one of the basic products available on the WSR-88D. Reflectivity shows where and how hard it is raining or snowing, as well as precipitation intensity trends and movement. Blue and green colors represent light-to-moderate rainfall. Yellow and orange colors show moderate-to-heavy precipitation, while red is very heavy rainfall and possibly hail. At left is a close-in view of a severe  thunderstorm over Mercer County in east-central Kentucky (west of Lexington) on May 11, 2003.  Although not classic in appearance, this is a supercell thunderstorm with a hook echo on the southwest side of the storm. This storm produced a tornado over central Mercer County that produced F1-F2 damage. More information and radar images on this May 11, 2003 severe event are available.
