A wet end to October was both a blessing and a curse. October ranks as the 18th wettest October on record (1895-2020) for Ohio, with much of the state picking up 3-8” of liquid-equivalent precipitation. Unfortunately, this slowed harvest with moisture content in corn remaining high. However, we have seen significant improvements in the U.S. Drought Monitor, with only about 7% of Ohio currently experiencing abnormally dry or moderate drought conditions (Fig. 1).

Ohio’s weather has been dominated by high pressure this past week, with many locations reporting record highs over the weekend. In fact, Dayton set a monthly record high of 80°F for November.
