Temperatures drop as morning fog shrouds Chicago skyline
SUN-TIMES MEDIA WIRE June 18, 2013 7:26AM
A thick fog that developed on Lake Michigan overnight spread to Chicago Tuesday morning, obscuring the city’s iconic skyline in a mist.
While the fog is expected to burn off in the late morning, the cold front that produced it is expected to drop temperatures across the region after several days of temperatures in the 80s, according to the National Weather Service.
The morning fog is the product of lingering moisture that melded with cool Canadian air moving into the area, said Ben Deubelbeiss, a meteorologist for the National Weather Service.
“There’s a nice little Canadian air mass that’s settling over us,” he explained. The fog “will linger a few hours and mix out as we get some good daytime heating late this morning,” he said.
The cold front that produced the fog, however, is predicted to drop lakefront temperatures into the 60s for the duration of the day, Deubelbeiss said.
Inland temperatures will likely be a bit warmer, but are still expected to dip into the 70s, he said.
The warm weather is expected to return on Thursday, with temperatures forecast in the 80s, according to the weather service.
