Illinois wakes up to a sharp, smoky risk this morning as dry air and steady southwest winds begin to stir across the Chicago area, pushing conditions toward rapid fire spread by midday. Grass and brush could ignite quickly, especially along open fields near I-55 and I-80 where winds pick up.
According to the National Weather Service in Chicago/Romeoville, southwest winds will gust near 20 to 25 mph through the afternoon while humidity stays low, creating elevated fire weather conditions across northern Illinois and northwest Indiana. Outdoor burning should be avoided immediately.
In Chicago, temperatures climb from near 30°F early into the upper 40s by afternoon under bright sun, but the wind adds a biting edge. Suburbs like Naperville and Joliet will see similar conditions, with dry vegetation posing the biggest concern. Plan carefully if working outdoors. One spark could spread fast.
By Sunday, warmth builds into the low 60s with continued breezes, keeping fire risk in play. The bigger shift arrives Monday night when a developing storm system brings scattered thunderstorms into the region. Roads could turn slick after sunset, especially on I-290 and Lake Shore Drive.
Tuesday brings the most disruption. Showers and storms become more widespread after 1 p.m., with rain chances near 80 percent and breezy conditions. Visibility may drop quickly during heavier downpours, slowing the evening commute.
Looking ahead, cooler air returns by midweek with highs falling back into the low 40s. More advisories may follow as this active spring pattern continues.
