A team of scientists from three universities has developed a weather-prediction system that will allow forecasters to predict tornadoes and other severe storms at least three days before the storms start. Here, you see Dr. Charles Doswell III viewing a large tornado in Throckmorton, Tex., on 04 April 2002 (Credit: Vicki Doswell). Learn more at NSF’s website devoted to science outcomes, SEE Innovation
