An artificial intelligence (AI) tool built by the U.S. National Science Foundation National Center for Atmospheric Research (NSF NCAR) can help forecasters look further into the future as they work to identify the potential for deadly severe weather outbreaks. NSF NCAR's Medium-Range, Real-Time Convective Hazard Forecasts leverage AI weather models—which tend to outperform traditional models in the three- to eight-day time horizon—with the goal of improving our ability to predict the potential for tornadoes, large hail, and damaging winds a full week in advance. The experimental forecasts, which are run daily and made available online, will be evaluated over the coming weeks at NOAA's Hazardous Weather Testbed as part of the Spring Experiment. This annual program tests the utility of emerging scientific tools for front-line forecasters during an especially active season for severe weather.…
