Chicago is waking to mostly clear skies, calm winds and temperatures around 66 degrees early Friday. The city should stay dry and sunny through the afternoon, with a high near 80. After that easy start, the forecast takes a hotter and more humid turn next week.
Sunny Friday Leads Into A Partly Cloudy Weekend
Friday will bring light south-southeast winds, mostly sunny skies and no meaningful rain threat. A weak lake breeze could develop during the afternoon, according to the National Weather Service Chicago/Romeoville, but it should not disrupt most outdoor plans.
Friday night will be partly cloudy with a low around 66, followed by a partly sunny Saturday with a high near 81. Saturday night turns mostly cloudy, with a low near 70, south winds of 10 to 15 mph and only a limited chance of rain.
Heat Builds Into The Start Of September
Sunday should be mostly sunny and warmer, reaching about 86 degrees, while Monday climbs to 88 and Tuesday approaches 89. The National Weather Service expects humidity to increase as well, with heat indexes potentially reaching the upper 90s by the middle of next week.
That is a notable warm-up from the earlier outlook covered by Hoodline, which had called for a cooler Friday near 77 degrees. The latest forecast now points to a longer stretch of late-summer heat rather than a brief warm spell.
Storm Chances Stay Scattered
Rain and thunderstorm chances remain intermittent rather than constant. A slight chance arrives Sunday night, with additional low-end chances early Monday and Tuesday, followed by a 40% chance of showers and thunderstorms Tuesday night.
Wednesday could start with a few showers before turning mostly sunny, while Thursday carries another slight storm chance before early afternoon. No watches, warnings or advisories are currently in effect, but Chicagoans planning outdoor activities should keep an eye on the forecast as the hotter pattern settles in.
