Bruce Smith

Meteorologist - in - Charge,

NWS Grand Rapids

Probabalistic Forecasting and the social science behind public response

With nearly 36 years in the National Weather Service, Bruce Smith — Meteorologist-In-Charge (MIC) at WFO Grand Rapids — has had a front-row seat to the transformation of modern forecasting. His NWS journey began as a student volunteer in Houghton Lake (1988) and Ann Arbor (1990) before officially launching his career at WSO Lansing in December 1990. Over the decades, Bruce served as Journey and Lead Meteorologist in Detroit, Science and Operations Officer and MIC in Gaylord, Science and Technology Integration Division Chief at Central Region Headquarters in Kansas City, and ultimately MIC at Grand Rapids beginning in 2022.  In his presentation, Bruce will lead a group discussion on how advancing deterministic and ensemble numerical modeling has revolutionized weather forecasting, the communication of uncertainty, and overall weather services. He will dive into the weather enterprise's recent shift toward probabilistic forecasting, examining how people interpret probabilities and exploring the social science behind public response.
