Geography

Ohio Climatic Division 1 is bounded at its northeast corner by Lake Erie. From the northern boundary at the Michigan border, it extends south to include, Lima, Findlay, and Van Wert. The terrain is almost entirely dedicated to agriculture.

Overview

The northeastern corner of the division, near the Toledo area, sees some lake effect during periods of easterly winds, and local lake breezes often moderate temperatures during the summer months.  For the most part, however, the climate is continental and driven by the movement of pressure systems across the country. As such, the division does not usually experiences prolonged periods of extreme heat and humidity in the summer or extreme cold during the winter. Summers are generally quite warm, especially in the inland areas, and winters, while not as severe as in more northern locations, can be cold with moderate to heavy snowfall.
