CHICAGO – Unseasonably warm, dry, and windy conditions will raise the risk of grass and field fires across northern Illinois and northwest Indiana through Sunday afternoon, with gusty winds also stirring areas of blowing dust near active harvest fields.
According to the National Weather Service in Chicago/Romeoville, a Special Weather Statement is in effect for much of the region, including Chicago, Rockford, Joliet, Kankakee, Gary, and Valparaiso. Southwest winds will gust up to 30 mph as afternoon temperatures climb into the upper 70s and low 80s. Relative humidity will dip to around 25–30%, creating an environment favorable for fire ignition and rapid spread.
Forecasters warn that grass, brush, and field fires may become difficult to control, especially in open rural areas. Residents and farmers are urged to avoid outdoor burning, properly dispose of cigarettes, and use caution with equipment that could spark near dry vegetation.
In addition, dust from harvest activity may temporarily reduce visibility, particularly along east–west roads such as I-80, I-88, and U.S. 24 in open farmland. Drivers should slow down and use headlights if visibility suddenly drops.
Fire officials across Illinois and northwest Indiana stress the importance of staying alert to local burn bans and keeping water or extinguishers on hand if working outdoors. The fire danger will ease overnight as winds subside and humidity rises, but dry conditions will persist into early week.
