Chicago, IL – The National Weather Service (NWS) Chicago is forecasting a stretch of seasonable but breezy weather through midweek, followed by two rounds of rain to close out the week. Residents can expect mild conditions through Wednesday before a frontal system brings widespread showers starting Thursday night.
Midweek Outlook: Breezy and Mild Temperatures Across the City
Forecasters say Tuesday will remain partly sunny and breezy, with highs ranging from the low to mid-60s and overnight lows settling into the upper 40s to low 50s.
Wednesday will feature similar temperatures but with stronger winds, as gusts could reach up to 35 mph. Despite the wind, skies will stay mostly clear, creating comfortable fall conditions ideal for outdoor activities.
According to NWS Chicago meteorologists, the breezy pattern is the result of a tightening pressure gradient behind a passing low-pressure system. The mild temperatures, especially near Lake Michigan, will keep conditions relatively stable through midweek.
Late-Week Forecast: Rain Arrives Thursday Night into Friday
Thursday will bring increasing clouds as a frontal boundary approaches from the west. Rain chances rise to 50–70% by Thursday evening, with showers expected to continue into Friday morning before tapering off by midday.
Forecasters warn that commuters on Friday morning should plan for wet roads and reduced visibility, especially during rush hour. While rainfall totals are not expected to be excessive, light to moderate showers could impact outdoor events and travel schedules.
“We’re looking at a pattern shift late in the week as the next system brings rain and cooler temperatures,” NWS meteorologists said Tuesday. “Drivers should plan for slick conditions and allow extra time for travel.”
Weekend Outlook: Cooler Air and Spotty Showers Return
After a brief break Friday afternoon, another weak disturbance will bring a second round of light rain on Saturday. Temperatures will turn noticeably cooler, with highs falling into the upper 40s to mid-50s and overnight lows dropping into the 30s.
Winds are expected to remain moderate, and skies may partially clear by Sunday, offering a cooler but drier finish to the weekend.
