CHICAGOLAND DETAILS …
Radar is clear in northeast Illinois.

Increased grass/brush fire threat today due to unseasonably warm, dry, and breezy conditions. Warm conditions, southwest winds gusting as high as 25 mph, and relative humidity falling as low as 25 percent will result in an increased grass and brush fire threat this afternoon. Use extra care with any outdoor activities that involve open flame or sparks, including operating farm equipment, parking on grass, and improperly discarding smoking materials.
Periodic shower and thunderstorm chances return Friday and into next week. Low (level 1 out of 5) severe weather threat as early as Friday afternoon, but mainly Friday evening/night along with a threat for locally heavy rainfall.
