The headline the next 10 days for the middle third of August will be below normal temperatures, about 2-4 degree below normal. Rainfall is now in a more normal mode through much of August with more variability to the pattern. If anything like we talked about in July, the tendency will be on the slightly drier side of normal but nothing real extreme the next few weeks. In fact some of the lower rain totals the next 16 days will be in our region of the corn and soybean belt.

Rest of August Outlook:
After August 20, temperatures will return to a few degrees above normal and rainfall close to normal. Therefore, August will likely end the month within a degree of normal either side and rainfall will be variable and end the month within an inch of normal most places.
Fall Harvest Outlook:
Confidence is high we will have above normal temperatures and delayed freeze risk this fall. Wetter than normal soil moisture will mean night time minimum temperatures will be held up some resulting in normal to 1 or 2 week delays in freezing temperatures. Confidence is low in the harvest rainfall outlook. It appears any drying from August into September could be replaced by wetness sometime in later September through November.
The latest two week rainfall forecast from the NOAA/NWS/Ohio River Forecast Center can be seen i the attached graphic. Generally 1-2 inches are forecast on average in Ohio the next 14-16 days which is normal to slightly below normal in most places. Isolated totals will be higher.
