The Chicago area is in for a hot and stormy stretch of weather this week, with scattered thunderstorms and sweltering heat continuing through Saturday. Temperatures will soar into the low 90s, and the chance of storms will remain high each afternoon and evening. Residents are advised to stay weather-aware, limit outdoor activities during peak heat, and take precautions to stay cool.
Scattered Storms and Hot Temperatures
According to the National Weather Service in Chicago, residents can expect daily chances for isolated to scattered thunderstorms through Saturday.
The hottest days will be Wednesday through Friday, with daytime highs ranging from 88°F to 92°F. Overnight temperatures will remain mild, ranging from the mid-60s to low 70s, providing little relief from the heat.
In Cook County, storms are likely to develop along major travel routes such as I-55, I-80, and I-294, particularly during the evening commute. These storms pose visibility risks and could cause dangerous hydroplaning conditions for drivers.
While areas near Lake Michigan, such as Rogers Park and Hyde Park, might experience slightly cooler temperatures, they will still be vulnerable to passing storms.
Storm Timing and Risks
The highest chances for storms appear on Wednesday night and Thursday afternoon. While severe weather is unlikely, there is still a possibility of brief heavy downpours, strong winds, and the potential for power outages in stronger storm cells. As a result, residents should remain alert and stay prepared for sudden weather changes.
Heat and Health Precautions
With temperatures consistently in the 90s, it’s essential to take precautions against heat-related illnesses. The National Weather Service recommends limiting outdoor activities during peak heat, staying hydrated, and seeking air-conditioned spaces whenever possible. People are also encouraged to check on vulnerable individuals, such as the elderly and young children, who may be more susceptible to the heat.
Weekend Outlook
The high heat and storm chances will persist through Saturday evening, but a cooldown is expected to begin on Sunday. The weather will start to dry out, with slightly cooler temperatures in the range of 82°F to 87°F, offering a welcome break from the sweltering heat and storms.
The Chicago area will continue to experience high heat and scattered thunderstorms through Saturday. Residents should stay informed about changing weather conditions, take precautions against the heat, and prepare for the possibility of strong storms and brief power outages. Relief will arrive by Sunday with cooler temperatures and a drying trend.
