Our team of meteorologists will be able to use this mode to focus on areas where high-impact weather is imminent or actively developing.National Weather Service Warning Coordination Meteorologist Freddie Zeigler compared the new model to football, saying, “I will say if you have a defense that has eleven men on the field as far as football, this is like having fifteen.”He says this new advantage will help his office and local meteorologists have more detailed information and longer forecast lead times than previous models.“I think one of the best, the best thing about this one is that it improves the probability of thunderstorms developing um, severe weather, storm coverage, the timing of beginning and end.”The new model has been years in the making, with lead scientists across the country modernizing traditional forecast products and replacing aging systems.Updating hourly, the model will be continuously updating itself, correcting any faulty inputs and consistently making itself better to improve near-term forecasting. Ken Graham, the director of the National Weather Service, said in a statement, “The higher precision provided by this model helps our forecasters issue better forecasts, warnings, and decision support for local emergency managers and meet our core mission to save lives and protect property.”It’s a mission that Ziegler takes seriously, especially as we transition into an El Niño winter with warmer temperatures and mixed sleet, and freezing rain possible.“Is there going to be a freezing rain in a transition or are you going to be be in a steady state across the area? Is it going to sleet for three hours or two hours? It can — hopefully it will give us a better understanding — a better assessment of the precipitation type,” Zeigler saidRegardless of season, this new model will continue to get better with time, giving meteorologists and emergency managers the tools we need to keep you safe.</div></body>
