Chicago, IL – Illinois residents can expect a cooler start to the week with below-average temperatures dominating the early part of the forecast. Highs will range from the low 70s to upper 70s through Wednesday, offering a brief respite from the usual summer heat. However, temperatures will begin to rise as the week progresses, reaching the mid-80s by Friday and climbing into the low 90s over the weekend.
According to the National Weather Service (NWS) in Chicago, a quiet weather pattern will persist, but residents should be aware of dangerous swimming and lakeshore conditions along Lake Michigan. Gusty onshore winds are generating waves of 5 to 8 feet, creating life-threatening swimming conditions. These hazardous conditions are expected to continue through Tuesday evening, affecting beaches and shorelines in Illinois and northwest Indiana.
Residents and visitors are urged to avoid lakeshore parks, trails, piers, and docks, as large waves may inundate these areas. The NWS advises staying out of the water and obeying all posted signs and closures.
