CHICAGO (CBS) — Dense fog is expected to continue pushing through the Chicago area throughout Sunday night and into the early morning hours on Monday.

The National Weather Service issued a dense fog advisory Sunday morning for much of northern Illinois and northwest Indiana. Widespread fog, which could cause visibilities to drop to a quarter-mile or less, should begin affecting the area after 7 p.m.

The advisory will remain in effect until 3 a.m. Monday in Cook, Lake, Will, De Kalb, Kane, DuPage, Kendall and Grundy counties, the weather service said. Winnebago, Boone, McHenry and Lake counties will remain under the advisory until 6 a.m. Monday.

Drivers should use caution while traveling on foggy roadways and “be prepared to encounter rapidly changing visibility,” the weather service said.

A chance of drizzle is also expected Sunday evening, with stronger rain showers pushing through the area after 10 p.m. alongside cooler temperatures that are expected to dip below 40 degrees, the weather service said.

On Monday, showers and thunderstorms are expected to hit the area after 9 a.m., the weather service said. Temperatures are expected to reach 48 degrees before dropping more than 15 degrees in the nighttime hours. Snowy, colder conditions are then expected to move through the area on Tuesday.
