National Weather Service Upgrades Weather Radars

CHANHASSEN, Minn. — The National Weather Service (NWS) has successfully completed a significant upgrade to its weather radar network after nearly a decade of work. This extensive system, comprising 159 radars across the United States, plays a crucial role in monitoring atmospheric conditions. Nick Carletta, a lead forecaster at the NWS office in Chanhassen, emphasized the importance of radar technology, stating, "Radar is honestly one of the most valuable tools we have." The original Next Generation Weather Radar (NEXRAD) technology, which has been in operation since the 1980s, required modernization after decades of continuous use. The upgrade, part of the Service Life Extension Program, involved an investment of $150 million and included new hardware as well as software enhancements. Carletta noted that the collaboration between research meteorologists and operational staff has been vital in integrating new radar techniques into the updated system. The completion of the upgrades in Chanhassen in 2020 has already shown positive results. Carletta expressed confidence in the reliability of the new equipment, particularly during severe weather events. "Because the parts are new and updated... we can have confidence that during the most critical severe weather it will keep spinning," he stated, highlighting the radar's essential role in weather forecasting and public safety. This modernization effort marks a significant advancement in the NWS's capabilities, ensuring that meteorologists can effectively monitor and respond to changing weather patterns across the nation.
