Latest Seasonal Outlook for IL

Illinois has higher odds of being both warmer and drier than average though June, according to the newly released NWS Climate Prediction Center outlooks.

The increased odds of drier conditions through June could be a concern. However, I am more confident in the temperature forecasts from CPC than I am of the precipitation forecasts.
