Geography Indiana Climatic Division 3, while somewhat removed from the Great Lakes, still lies partially in the Great Lakes Watershed. It borders Michigan to the North, Ohio to the east, and extends south to include Fort Wayne. The terrain is almost entirely dedicated to agriculture. Overview The climate is continental, driven by the movement of pressure systems across the country. Large daily variations in temperature are more common than in climatic divisions nearer the Great Lakes. But as with the surrounding region, the division does not usually experience prolonged periods of extreme heat and humidity in the summer or prolonged, extreme cold during the winter. Summers are generally quite warm, and winters, while not as severe as in more northern locations, can be cold with moderate to heavy snowfall. Lake-effects are limited, but lake-effect snowfall off of Lake Michigan during periods of northwesterly winds are not unheard of.


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.
