CHICAGO (CBS) — Clouds and patchy fog will continue through the afternoon, as temperatures once again top out in the 40s.

CBS 2 Meteorologist Mary Kay Kleist says the fog in the area has improved since the morning rush, with visibility now up to 3 miles in outlying areas, 5 miles at Midway International Airport, and 6 miles at O’Hare.

The temperature was 32 degrees at O’Hare at 11 a.m., and is expected to climb to 41 degrees in the afternoon with southwest winds around 10 mph.

The low drops to 32 overnight with clouds remaining.

But on Tuesday, a cold front will drop down from the north, bringing a chilly air mass south from the Canadian border. Meanwhile, a low pressure system will blow up from the southwest.

This could mean snow during the day Tuesday, but Kleist says snowfall will be limited to the daytime hours and will only produce a dusting at the most.

The cold front is not expected to result in any dramatic chill either. The high for Tuesday is 35, and for Wednesday 32.
