August continued the warmer than normal trend. However, Ohio did get some beneficial rain which helped some. June to August will go down as about 2-3 degrees above normal and precipitation 60-100% of normal (below) north half of Ohio and 100-125% of normal (slightly above) in the south half. It was the tails to two states that can be seen in the graphics attached form the Midwest Regional Climate Center.
As discussed a few weeks ago, it looks like the helpful rain in many areas was a pause in a preferred warmer and drier than normal pattern. All indications are September will be warmer and drier than normal for much of the state. It may turn wetter again toward the end of September.
September will start the first few days with a fall-like shot of cooler air with lows mostly in the 50s and highs in the 70s. A few upper 40s in low lying areas later this week can't be ruled out but 80s will return quickly by this weekend into next week with a few highs in southern areas near 90.
The NOAA/NWS outlook for first half of September in the attached graphics shows the warm and drier weather. Temperatures will respond 3-5F above normal with a few days being at least 10F above normal in September.
