Radar allows us to show where storms are occurring and their strength. A new generation of radars called Doppler radar has replaced WSR-57 (Weather Service Radar 1957) radars. These Doppler radars are given the name NEXRAD which stands for Next Generation Radar. These new radars improve the ability of a forecaster to identify where severe weather, such as heavy rain, hail, or tornadoes, is occurring. This exciting new technology shows dramatic improvement over the WSR-57 radars.
