The temperature will be average above normal during September. Precipitation will also be above normal for the month.
Summer-like weather will continue over much of Ohio during the first half of September. A high pressure system centered over the Atlantic Ocean will transport warm, humid air over the state.
The high will keep temperatures warmer than normal and the humidity will contribute to the development of showers and thunderstorms. The high could weaken a little during the second half of September. If the high weakens, then weather systems moving across the northern U.S. will brings periods of cooler, drier air to Ohio.
Overall, our pattern of warmer than normal temperatures and wet weather is likely to continue in September.
