State Climatologist, Justin Glisan, says June, July and August have been warmer and drier than normal for the last three years. Glisan says the La Nina weather pattern is to blame and it could impact fall as well.
He says La Nina is a cold sea surface temperature anomaly in the Pacific that impacts where the storm tracks set up over the United States. It could hang around through winter.
Glisan say the La Nina impact has been felt across much of the upper Midwest.
