Weather Outlook and El Nino Update

Not much change from previous weeks thinking. Temperatures will average normal to slightly above normal for the rest of August while rainfall will be close to normal or slightly below. Nothing extreme is forecast.  See the 8-14 temperature and precipitation outlook maps at the following links:

Going into autumn and harvest season, climate models continue to suggest a turn to wetter conditions again across the corn and soybean belt including Ohio which would make harvest season a bit tougher. The good news for harvest season is frost and freeze dates could be delayed.

El Nino is well underway in the eastern Pacific Ocean of the equatorial region. This El Nino is shaping up to be a strong one from the second half of 2015 into 2016. The effect will likely extend from winter wheat season into planting season and possibly beyond for 2016. This El Nino of 2015 into 2016 will likely be similar to the years of 1997/98, 1982/83, 1972/73 and 1957/58.
