William M. Gray is an internationally known expert in the field of tropical storms and hurricane forecasts. He is professor emeritus of atmospheric science at Colorado State University.

William Mason "Bill" Gray was born on October 9, 1929. He earned his B.S. degree from George Washington University in 1952, his M.S. in 1959, and Ph.D. in 1964 from the University of Chicago. He married Nancy Price on October 1, 1954, and has three children, Sarah, Janet, and Robert.

Gray was recruited by Herbert Riehl, whom he studied under at the University of Chicago, to come to Colorado State University in 1961 to help develop a new department in atmospheric science. The department focuses on graduate education leading to the master's and Ph.D. degrees in fields such as cloud microphysics, severe storms and mesoscale meteorology, atmospheric chemistry and air quality, radiation and remote sensing, climate and atmosphere-ocean dynamics, and global biogeochemical cycles and ecosystems. He pioneered the concept of "seasonal" hurricane forecasting--predicting months in advance the severity of the coming hurricane season. Gray and his team working on the Tropical Meterology Project have been issuing seasonal hurricane forecasts since 1984. William Gray currently serves as a senior research scientist with the department of atmospheric science.
