Climatological summer (June-August) has come to an end and all eyes are now on harvest season. Overall, the summer of 2022 was average temperaturewise, with most of state seeing near to above average precipitation. The driest areas occurred over west central and northeast Ohio.
Over the last 30 days, precipitation has been plentiful for much of the state, running more than 200% of normal across countes near the Ohio River (Figure 1). CoCoRaHS observations for the month show numerous sites in central and southwest Ohio coming in with 6-9 inches of rain, while locations in Darke, Shelby, and Miami Counties have only picked up 2 inches over the last 30 days. This wet pattern has kept extreme heat in check, with temperatures running about average for August.
