Geography Ohio Climate Division 2 is bounded by Lake Erie to the north and extends south to include the cities of Mansfield, Ashland, and Galion. The terrain is predominantly gently undulating agricultural land that’s increasingly hilly to the south. Overview The climate of Ohio’s North Central Division is primarily continental, characterized by larger temperature ranges than in areas at the same latitude near the Great Lakes which have moderated temperatures. The division does, however, reside in the “snowbelt” of northern Ohio and can experience significant lake-effect snow. Temperatures are somewhat tempered by Lake Erie, but winters are typically cold and dry. Diminished wind speeds or winds which do not traverse large unfrozen lakes often produce clearing skies and the colder temperatures expected at continental locations. Because the day-to-day weather is controlled by the movement of pressure systems across the nation, this area seldom experiences prolonged periods of extreme heat or cold, though hot and humid days are more frequent than in more northerly locations. Precipitation is well-distributed throughout the year with slightly more rain falling during the late spring and early summer. Summer precipitation comes mainly in the form of afternoon thunderstorms.
In partnership with the Midwest Regional Climate Center and the Office of the Michigan State Climatologist, GLISA has developed summaries of the observed historical climate for NOAA U.S. Climate Divisions within the Great Lakes basin. Each summary includes an overview of temperature and precipitation to help guide local-level climate adaptation decisions.
