Overview

• Highs step from the low to mid-70s Monday to the upper 70s Tuesday, reaching the low to mid-80s Wednesday through Friday, with some inland spots near 86 degrees.
• NWS guidance keeps the area largely dry through at least Sept. 12, with only a slight (less than 20%) chance of light showers north of I-88 Tuesday night.
• Persistent easterly onshore winds will keep neighborhoods along Lake Michigan several degrees cooler than inland communities.
• The recent cool stretch was driven by a late-August to early-September cold air mass that produced below-normal daytime highs and chilly nights.
• Forecasters note typical late-week uncertainty, including the exact inland highs and whether next weekend trends warmer or turns cooler.
