New Climate Outlook for July and Summer – OK for Illinois

Today (June 19) the NOAA Climate Prediction Center has released their latest outlook for July and the rest of the year. One of the factors to come into play this fall and winter is the developing El Niño event in the Pacific Ocean. Unshaded areas show an equal chance (EC) of above, below, or near-average conditions.

For July, we have EC for both temperature and precipitation in Illinois, except for a slight risk of below-average precipitation in southern Illinois. We are sandwiched between cooler than average conditions in the north and warmer that average conditions in the south.




For July through September we have EC for both temperature and precipitation in Illinois. From the standpoint of the Corn Belt, the increased chance of cooler than average temperatures in WI, MN, and the Dakotas through September may spell trouble for getting the corn crop to mature in time this fall. Wetter than average conditions are expected in the central West, which could bring some relief to drought conditions in that region.




For December through February, the core winter months, Illinois and much of the northern half of the US has an increased chance of above-average temperatures. This forecast reflects the expectation that El Niño will arrive. El Niño tends to bring milder temperatures in winter for Illinois and wetter conditions in the Southwest and Southeast.
