Chicago, IL – Thunderstorms could arrive in Chicago as early as Sunday afternoon, bringing the first in a series of wet weather days that may stretch into midweek. Temperatures are expected to climb near 90°F, with high humidity pushing heat index values even higher before the storms roll through.
According to the National Weather Service, Sunday’s rain chances stand at 30% in the afternoon, increasing to 40% Sunday night as scattered storms develop across Cook County and surrounding areas. Gusty winds and heavy downpours could cause brief street flooding, especially in low-lying neighborhoods and near underpasses. Outdoor events, including lakefront activities and festivals, could be impacted by sudden weather changes.
The rain threat ramps up Monday, with a 60% chance of showers and thunderstorms, particularly after lunchtime. Commuters should plan for slower travel times, and those in flood-prone zones are advised to keep storm drains clear. More scattered storms are possible Tuesday before conditions ease by Wednesday.
Residents should monitor weather updates through early next week, as additional advisories could be issued if storms become severe.
