Chicago was waking up to clear skies and temperatures near 50 degrees Monday morning, with a sunny afternoon ahead and a high near 64. Rain is not expected, and the city should stay quiet weather-wise as the week gets started.

Tuesday Brings A Noticeably Warmer Turn

Tuesday will feel more like a mild late-summer day, with sunshine and a high near 71. South winds of 5 to 15 mph could gust as high as 23 mph, especially during the late morning and afternoon, so lightweight outdoor items may need a little extra securing.

Wednesday Could Reach The Mid-70s

Wednesday is currently expected to be the warmest day of the workweek, with sunny skies and a high near 74. West to northwest winds around 7 to 10 mph are expected, but the overall forecast remains dry and comfortable.

With highs reaching 74 by Wednesday, the week’s warmest weather arrives in the middle of the workweek. It is a mild stretch, rather than a return to summer.

Mostly Dry Weather Holds Through Sunday

Thursday should bring mostly sunny skies and a high near 68, followed by a mostly sunny Friday near 66. There is only a small chance of a sprinkle or light shower Friday, and Saturday and Sunday look warmer, with highs near 70 and 74, respectively.

Friday’s outlook remains mostly sunny, with only a small chance of a sprinkle or light shower.

Overnight temperatures will range from around 50 degrees Monday night to the upper 50s by Tuesday night, with another mild night expected Saturday. No watches or warnings are posted for the Chicago area, making this a straightforward week for commutes, errands and outdoor plans.
