Weather officials are issuing warnings related to particularly dry and windy conditions in the Chicago region on Wednesday afternoon, just hours after a phenomenon known as “dusty rain” left cars in the area marked with mud splatters. This unusual weather pattern followed overnight showers, which brought between 0.05 to 0.15 inches of rain across northeastern Illinois.
The National Weather Service (NWS) has placed a red flag warning in effect, indicating that the mix of warm temperatures and strong winds poses a significant risk for the rapid spread of brush fires. This advisory covers multiple counties, including Cook, DuPage, Will, Kankakee, and Lake, lasting until 8 p.m. Wednesday.
Forecasts predict southwest winds blowing at speeds of 20 to 30 mph, with potential gusts reaching as high as 50 mph. Coupled with humidity levels dropping to around 20%, any fire that ignites could escalate quickly, prompting officials to advise against outdoor burning.
The earlier showers were notable for being infused with dust from strong winds moving through the region and contributions from wildfire smoke and ash coming from the central and southern plains. This combination led to the precipitation being described as “dusty rain,” a term highlighted by the National Weather Service on social media, humorously pointing out the need for a car wash.
While the day’s high temperatures are anticipated to hover in the low 60s, the region will experience a significant drop overnight, with temperatures expected to fall to the low 40s. Residents are urged to remain vigilant during these dry and windy conditions as they navigate the potentially hazardous weather ahead.
