The second half of September will continue to experience above normal temperatures and close to normal rainfall.
Second half of September RISK:
Temperatures - Above Normal (+3-5F) - Normal highs are in the 70s and lows in the 50s.
Rainfall - Near Normal (0.5-1.5 inches) - Normal is about 0.6 inches per week.
Freeze - Below normal - Little if any expected.
The NOAA/NWS/Ohio River Forecast Center 16-day rainfall outlook suggests the wettest areas will remain west of Ohio. This trend will continue into October where wet conditions could hamper harvest especially west of Ohio.

October is shaping up to be above normal temperatures and near or slightly wetter than normal. Based on historic El Nino events, freeze conditions typically arrive a little later than normal so expect a week maybe two weeks of delay to freeze this fall.
October RISK:
Temperatures - Above Normal (0-+3F)
Rainfall - Near or slightly above normal.
Freeze - Below normal - Expect a later than normal freeze. Normally Oct. 10-20 across much of the state.
With a significant El Nino expected this fall and winter, everything suggests warmer conditions with below normal precipitation western Ohio and normal precipitation in eastern Ohio.
