Winter wheat

Looking ahead
There is a 70% chance that El Niño will continue through the Northern Hemisphere summer, according to the Climate Prediction Center. Chances are 55% to 60% that it linger through fall. All this suggest continued wet weather.

In its outlook for June, July and August, the CPC shows above normal chances of precipitation and a tendency for below normal temperatures in the Western Corn Belt/Plains. There is a better than usual chance for above normal temperatures in the East.
