Mix of warm temperatures, dry conditions raise risk of wind-driven fires
The Chicago area is under a fire watch Wednesday due to unseasonably warm weather, low air moisture and gusty winds, according to the National Weather Service.
With high temps forecast in the 60s and wind gusts topping out around 40 mph, the area is under heightened fire danger, according to the NWS. The weather conditions, including low moisture in the air and a recent lack of rain and snow, also could lead to a higher risk of rapid fire spread.
The fire weather watch is in effect through Wednesday evening across much of northern Illinois, including Cook, Lake, DeKalb and DuPage counties.
The combination of warm temperatures, dry conditions, and strong westerly winds will lead to an increased threat for fire spread tomorrow especially along and north of Interstate 88. Limit activities that may cause sparks or involve open flames. #ILwx #INwx pic.twitter.com/yGkzr1HvrJ

The NWS recommends against burning yard waste because of the likelihood for fires to spread.
“It’s getting warmer here, I’m sure a lot of people will be tempted to burn yard waste,” said NWS meteorologist Kevin Doom. “Maybe avoid that, but if you do just keep an extra eye on it … it can be really easy for a spark to run loose and ignite something else.”
Fire weather hazards are most common in the fall and spring, though they can happen any time of year, Doom said. He also cautioned people to use extra care when disposing of burning materials like cigarette butts.
Chicago set a record-high temperature Monday as the city recorded a 65-degree day.
