Chicago, Illinois – As Illinois heads into a sizzling holiday weekend, weather conditions are set to bring a mix of heat and sporadic storms, potentially complicating outdoor plans across the state.
Thunderstorm Chances Thursday Evening
The National Weather Service reports a 20% chance of thunderstorms in Chicago starting Thursday evening, with brief rain possible after 4 p.m. These thunderstorms should be short-lived, and skies will clear in time for a mostly sunny and dry Fourth of July.
Temperatures will rise to around 92°F, with mild southerly winds. Although the weather will be pleasant for outdoor celebrations, residents should still take care to stay hydrated and limit exposure during the peak afternoon sun.
Scorching Heat on Saturday
Saturday will bring the hottest day of the week, with temperatures reaching 96°F in Chicago. A summer weather alert is in effect, as high heat and humidity will make it feel even warmer.
While the day will be sunny, a slight chance of thunderstorms will return Saturday night and continue into Sunday afternoon and Monday night. The heat, combined with high humidity levels, will make conditions uncomfortable, especially near the lakefront and busy roadways like I-55 and Lake Shore Drive, which could see increased traffic due to July 4th travel.
Persistent Thunderstorms and Humidity
As we move into Sunday and Monday, expect a 30% chance of afternoon thunderstorms. Though storms are expected to be brief, they could still disrupt afternoon outdoor plans. Tuesday and Wednesday will see a continuation of scattered showers, particularly in the afternoon, though the rain chances remain relatively low.
Staying Safe in the Heat
With high humidity throughout the weekend, it’s important to take extra precautions. Residents are advised to check their air conditioning units, stay hydrated, and avoid prolonged outdoor exposure, especially during peak heat hours. Pet owners should also take care to keep their animals cool.
