Meteorologist Nick Dunn of WHIO's Stormcenter7 dropped by the PBS Building at the Mercer County Fairgrounds in Celina Monday night to deliver a talk on severe weather and how to stay ahead of it. Over 30 people attended the class to learn about useful weather apps and resources, severe storms, forecasting, weather terminology and more. The event was sponsored by the Shelby and Mercer county EMAs.
