A weak weather system interacted with moisture flowing northward into the area resulting in isolated thunderstorm developing during the afternoon and evening. One supercell strengthened just south of Dumas and dropped hailstones up to the size of quarters. As it moved into a more favorable environment over northern Potter County, the storm produced a brief tornado. As it continued eastward it produced hail as large as tennis balls near White Deer.
