Chicagoans can look forward to a pleasant Labor Day with sunny skies and a high near 76 degrees, according to the National Weather Service. The southeast wind will shift to east northeast in the afternoon. As the evening approaches, conditions are expected to remain mostly clear, with temperatures dropping to a comfortable low around 62.

The city is set to enjoy an extended period of fair weather through Tuesday, with the high-pressure system firmly keeping the skies clear and sunny. The forecast predicts a high near 78 degrees for Tuesday, with calm winds that are likely to pick up slightly in the northeast direction by the afternoon. However, come Wednesday, residents should be prepared to quickly shift gears, as a cold front is anticipated to bring rain and wind. A 50 percent chance of showers and thunderstorms is expected after 1:00 p.m., as reported by the National Weather Service.

As CBS Chicago notes, the forecast indicates that Wednesday's powerful cold front will usher in cooler temperatures, with a high of 77 degrees before dropping to a low around 50. Further, swimmers should take note of the high swim risk on Thursday, as conditions in the waters could become hazardous. CBS News Chicago's forecast includes highs dropping to a cool 65 degrees on Thursday.

The chillier air seems to stubbornly hang around through the end of the week, with a reinforcing shot of cold air expected on Friday. Though partly cloudy skies are predicted, the high is to only reach around 67 degrees. The cooling trend continues with Friday night lows anticipated to be around 51 degrees. The weekend, however, is expected to bring a return to mostly sunny conditions, with comfortable highs creeping back up to the upper 60s and low 70s by Sunday, CBS Chicago forecasts.
