Key Messages
- Dry fuels and low relative humidity will continue to provide an elevated risk for any afternoon agricultural field fires today, especially southeast of the Illinois river.
- The remnants of Hurricane Isaias are expected to mostly pass to the east of IL this weekend. However, there is a 10-15% chance of 1" of rain Saturday night into Sunday in the far southeastern counties (Crawford, Richland, and Lawrence counties).
