Growing up in the Midwest, Grant developed a fascination with thunderstorms, tornadoes, and blizzards at an early age. For a birthday present in high school, his parents took him to meet the local TV meteorologist in Kansas City, Bryan Busby. Six years later, he did an internship with Busby and credited him with his start in the business.
After graduating from the University of Missouri with a degree in Atmospheric Science, Grant began his career in meteorology at KMIZ-TV in Columbia, Missouri.
He also forecasted for KYTV in Springfield, Missouri. While in college, Grant was recognized for his undergraduate research on hurricanes and El Nino.
Grant left Oklahoma City in 2009 to enroll in the Dallas Theological Seminary and plans to continue working toward a master’s degree there.
When Grant is not on air or doing homework, he enjoys spending time with family and friends, running, flying, and composing music.
