Weather Update: A Dry Trend, Interrupted?

After a wet spring, June took a turn toward much drier conditions. Figure 1 shows that a large swath of the state only received 50-75% of normal precipitation, despite derechos and numerous pop-up thunderstorms throughout the month. Though locations around the state set both daytime maximum and nighttime warmth records, we also experienced several cool mornings due to dry conditions. This left the state running about 1-2°F above average for the month. The recent dry conditions have led to rapid drying of soils with reports of cracking, lawns turning brown, and crop stress including rolled corn and slow growth of soybeans. For the latest up-to-date conditions, seasonal outlooks, and monthly climate summaries, please visit the State Climate Office of Ohio.

A ridge of high pressure has set up to our southwest. This will leave Ohio in northwesterly flow on the northeast side of this high pressure. Temperatures will start out close to 90°F before cooling off into the mid-80s later in the week. Humidity will run high all week. Clusters of showers and storms will traverse the region, much like Monday, bringing repeated rounds of beneficial rain across the region. While the exact timing and location of each cluster is unknown far in advance, rainfall will add up over the course of the week. The Weather Prediction Center is forecasting a large area of 1.5-3.0”, lesser amounts in the far northeastern counties over the next 7 days (Figure 2).Figure 2

The Climate Prediction Center’s 6–10-day outlook for the period of July 11 - 15, 2022 and the 16-Day Rainfall Outlook from NOAA/NWS/Ohio River Forecast Center show average temperatures and precipitation are expected (Figure 3). Climate averages are nearing their annual peak during this period include a high-temperature range of 83-87°F, a low-temperature range of 62-66°F, and average weekly total precipitation of 0.85-0.90 inches.
