Key Messages
- No significant weather is expected across central Illinois through early next week. Low chances of showers (20-30%) in southeast IL overnight Saturday night and Sunday.
- Due to dry fuels and low afternoon relative humidity values, there is an elevated risk for agricultural field fires through Saturday especially southeast of the IL river where afternoon humidity levels will likely reach 30% or less.
