Despite extensive cloudiness and intermittent showers, temperatures across the metro area reached seasonable levels on Sunday.
Officially on Sunday, O'Hare International Airport registered a high of 50 degrees. The mildest air was felt across northwest Indiana, with the temperature at Valparaiso climbing to 55. Meanwhile, brisk northeast winds to 26 mph lowered the afternoon temperature at Milwaukee to 36 degrees.
While the sunshine will return, similar conditions to Sunday will have moved into Chicago by early Monday. With the open waters of Lake Michigan at 34 degrees, stout northeast winds will keep our readings in the 30s much of the day, especially near the lakeshore. NE winds will produce afternoon wind chills in the upper 20s to lower 30s.
Illinois and Indiana beaches will be on the receiving end of full-fetch lake winds, creating waves to 10 feet that may inundate low-lying shoreline areas.
An influx of milder air is forecast to sweep into the area midweek. We start to warm up Tuesday, and make a significant jump Wednesday with a good amount of sunshine. Southwest winds help temperatures into the lower 60s Thursday, despite more clouds and showers.
Rain is more likely Friday and it could be heavy. Precipitation is expected to linger into Saturday and we could see some snowflakes mixed with raindrops Saturday morning.
