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 Hart County in east-central
Kentucky (northeast of Bowling Green) on May 11, 2003. This storm had
supercell characteristics and was
embedded in a squall line over central Kentucky. The storm produced wind
damage and an F0-F1 tornado near Munfordville. More information and
radar images on this May 11, 2003 severe
event are available. |
