Introduction of the Next Generation Weather Radar (NEXRAD) system will usher in a new era of precipitation processing for the US National Weather Service (NWS). Precipitation processing is performed in three stages. Stage I of processing occurs within the NEXRAD computer system and produces quantitative precipitation estimates, short-term forecasts of precipitation accumulations and flash-flood probabilities. Stages II and III, performed at NWS forecast offices external to NEXRAD, will further improve the quality of precipitation estimates through the use of satellite imagery, raingage data, and eventually other hydrometeorological information. NEXRAD data, combined with rangage, and satellite data, will lead to large improvements in the accuracy of precipitation estimates. -Authors
