High temperatures are forecast to climb into the 70s Sunday as south winds and ample sunshine deliver holiday warmth. Winds cutting in off chilly Lake Michigan, however, will keep areas along the north lakeshore a bit cooler. It should be the city’s warmest Easter in four years since a 76-degree high on April 4, 2010.
A cool-down will follow the passage of a cold front Monday, which will be accompanied by showers and thunderstorms. Despite the Chicago area’s very snowy winter, precipitation since March 1 is running about 1.5 inches below normal. A return to cooler weather is expected Tuesday and Wednesday before another round of showers and thunderstorms arrives Thursday setting the stage for a chilly weekend with temperatures forecast to only reach the lower 50s Saturday.
