Residents of Chicago can expect a brief respite from the heat and humidity this week, with cooler and more comfortable conditions Tuesday and Wednesday. However, the oppressive summer weather will return just in time for the July 4th holiday weekend, bringing intense heat and scattered storms.
Short Break from the Heat
According to the National Weather Service in Chicago, Tuesday and Wednesday will provide a break from the stifling humidity. Temperatures will remain in the mid-80s, especially near Lake Michigan, offering a more pleasant atmosphere. However, by Thursday, the humidity will start to climb again, and there’s a 20% chance of storms, signaling the return of uncomfortable conditions.
Hot and Humid Conditions for the Weekend
From Friday through Saturday, the heat will intensify with highs ranging from 90°F to 95°F. Heat indices, which reflect how hot it feels with humidity, could exceed 100°F, especially in inland areas. The peak heat is expected on Friday afternoon, which could disrupt outdoor activities and increase the risk of heat-related illnesses.
The Illinois Department of Public Health is urging residents to stay hydrated, avoid outdoor activities during peak heat, and check on vulnerable neighbors, such as the elderly or those with health conditions.
Storms and Traffic Hazards
While storm chances remain low through midweek, the likelihood of scattered storms will rise as the weekend approaches. Friday and Saturday could see brief interruptions to fireworks events due to the storms. Additionally, drivers across Cook, DuPage, and Will counties should remain alert for sudden downpours that could reduce visibility, especially on highways like I-80 and I-55.
Heat Advisories Likely
As the heat builds toward the weekend, the National Weather Service may issue heat advisories if the conditions worsen. Residents are encouraged to stay prepared and follow safety recommendations to protect themselves from the extreme heat.
