AUGUST WEATHER OUTLOOKWritten by Jay Hobgood, Ph. D., Ohio State University
The temperature will average slightly above normal during August. Precipitation will be above normal for the month.
An upper level trough over the Great Lakes and Ohio River Valley will contribute to a cool, wet start to August. An upper level ridge will move over the area during the second week of the month and the temperature will be above normal. The ridge will shift back over the western U.S. later in August which will let the temperatures over Ohio be closer to normal. We could see the first hints of fall when cooler air from Canada moves across the Great Lakes during the second half of the month.
Overall the average temperature is likely to be slightly above normal. A surface high pressure system centered over the Atlantic Ocean will circulate humid air over the state in the lower levels.
The strongest flow of moist air will be over eastern Ohio and the heaviest rain will fall in that part of the state. Typical summer showers and thunderstorms will form in the humid air and we are likely to see above normal rainfall during August.
