Weather Update: Unsettled Weather Continues


Over the last two weeks, a more active pattern has brought numerous rounds of showers and thunderstorms across the Buckeye State. Many areas, from west central to southeast Ohio have received 2 inches of rain or more, with pockets of 4-6 inches across western Franklin, Fairfield, and Perry Counties. This has resulted in a decline in drought areas from 78% to 33% as of Thursday, June 22, 2023 (US Drought Monitor), leading to some improvement in crop conditions. However, large portions of southwest, northwest, and northeast Ohio have received less than normal precipitation over this period (Figure 1)Figure 1: Percent of normal precipitation over the last 14-days ending June 26, 2023.
