  1. CFAES Ag Weather System 2021 Near-Surface Air and Soil Temperatures/Moisture

    Author(s): Aaron Wilson , Author(s): Greg LaBarge, CPAg/CCA

    Soil temperatures continued to warm this week despite considerable variability in air temperatures (Fig. 1). Many locations throughout Ohio are now reporting daily average 2- and 4-inch soil temperatures in the mid-50s to low-60s. Daily maximum soil temperatures are routinely reaching 80°F with the increasing sun angle. Warming progress is likely to slow a bit this week. While daytime highs are expected in the 70s again on Tuesday, 50s and 60s are likely behind a cold front for the remainder of the week.

    Author(s): Aaron Wilson

    Much of Ohio experienced frost or freeze conditions this past Friday and/or Saturday night. In fact, many locations dropped below 30°F (Table 1), with unofficial observations as cold as 26°F! How does this compare to typical first freeze dates?

  6. We Now Turn Our Attention to Autumn Harvest Season

    The cooler than normal blob of water in the eastern Pacific Ocean near the equator tends to push the first autumn freeze later than normal in our region. Therefore, there is no indication of an early freeze in September this year. It appears the first freeze for Ohio will not come until October either on schedule or a bit later than normal.

  8. Drought Conditions Expand but Some Relief Ensues

    Author(s): Aaron Wilson

    As of the Thursday July 30, 2020 release of the U.S. Drought Monitor, 37% of the state is covered by D1- moderate drought conditions (Figure 1). Hot and mostly dry conditions continued through much of June and July, with only scattered areas of heavy rain throughout the state. This has depleted soil moisture and lowered stream flows. If you are seeing drought impacts in your area, consider submitting a report to the Drought Impact Reporter.

  9. 16-day Mean Precipitation

    Climate and Hydrology Pattern to Relax in August

    The overall drier pattern in many but not all places in Ohio this summer appears like it will relax closer to normal in August. The greatest uncertainty with the outlook will center around how the tropical moisture impacts the eastern United States.

Temperatures this past week averaged 2-8°F above normal, with the warmest conditions compared to average across northern Ohio.
