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.

Warm and dry conditions will continue into Tuesday before a cold front moves through the region. Rain showers are likely late Tuesday afternoon through Wednesday morning, with high pressure and dry weather resuming for Wednesday afternoon through Saturday. While the next couple of days will see highs in the 70s, Wednesday’s highs are expected in the 60s, with highs Figure 2: Forecast precipitation for the next 7 days.

Our next opportunity for rainfall will occur on Sunday and Monday.
