Chicago starts Thursday, July 30, near 64 degrees with clear skies and calm winds, but the quiet weather will not last through the weekend. A sunny afternoon and a high near 79 will give way to rain late Friday, followed by a potentially soggy Saturday across the city.
Sunny Thursday, Then Rain Arrives Friday
Thursday should stay dry and bright, with south winds around 0 to 5 mph and temperatures reaching about 79 degrees during the afternoon. On Friday, July 31, skies will turn partly sunny with a high near 80, but rain showers could begin after 4 p.m., according to the National Weather Service Chicago.
Heavy Rain Threat Peaks Friday Night Into Saturday
Rain is expected to become more widespread Friday evening, with a slight chance of thunderstorms and a 90% chance of precipitation. Some storms could produce heavy rain, and forecasters say much of the area could receive more than an inch, with localized totals topping 2 inches.
The risk is more important for the Chicago metro, where recent storms have left some soils wetter and lowered the threshold for localized urban flooding. The National Weather Service says heavier rain bands could create a flash-flood concern in spots, though no watches, warnings or advisories were in effect Thursday morning. Hoodline’s earlier Chicago forecast covered the stormy stretch that helped set up those wetter conditions.
Saturday Stays Cool And Wet
Saturday, August 1, will begin with rain before 7 a.m., followed by likely showers through the day. The high should reach only about 73 degrees, with northeast winds around 15 mph and gusts up to 25 mph, making for a rougher day for outdoor plans and a potentially messy commute.
Sunshine Returns Sunday
The pattern improves Saturday night, with only a 30% chance of lingering showers before mostly cloudy skies take over. Sunday, August 2, should be mostly sunny with a high near 74, followed by sunny weather Monday near 79 and another warm, dry day Tuesday with a high around 84.
