May worked out as forecast with a wet start followed by a gradual planting window.
Looking forward, the variable weather pattern continues in the short-term with temperatures continuing to fluctuate.
For June, we expect slightly cooler than normal temperatures to persist until mid-month (-1 to 3F). Temperatures are likely to switch to above normal for the second half of the month (+1 to +4F). Confidence in this is medium to high.
Rainfall will be much more variable and scattered ranging from 0.50 inches to over 3 inches through June 20th (see attached rainfall forecast map for the next two weeks) You can also see this on the NOAA NWS Ohio River Forecast Center webpage at:
Normal is about 1.5 to 2.0 inches. Confidence on where it will be drier or wetter is low as thunderstorms will drive the details of the outcome.
Rest of growing season outlook
The outlook for July is for a warmer month with rainfall near normal (but the normal rainfall will be made up of anything but normal). Most areas will either be above or below normal rainfall in July but as a statewide average near normal is anticipated.
The warmer weather will persist into August with a trend toward normal or below normal rainfall. The question will be the preferred tropical track of tropical systems. Currently, most climate models indicate this will be from the Gulf of Mexico to the Southeast U.S. This will likely leave Ohio in the normal or possibly below normal precipitation category.
Fall harvest season
Early Indications for harvest season are for a warmer and drier than average pattern with low chances for early freezes.
