Dense fog limits visibility in Metro Detroit

Rush-hour Wednesday commuters beware: a dense fog advisory has been issued in Southeast Michigan, and visibility is as low as 1/16th of a mile and only as high as a half-mile.

The advisory is in effect through 10 a.m., said National Weather Service meteorologist Jordan Dale. 

The heavy fog owes to the high moisture levels in the ground after the rain the last two days, plus clear skies Tuesday night, which dropped temperatures quickly. 

The fog is expected to clear by mid-morning, though, and Wednesday could reach 80 degrees under sunny skies. Overnight, lows will hit the 60s.

Thursday and Friday will cool down a bit, should be similar, but high temperatures are expected to fall back to the low 70s, and possibly as low as the high 60s. 

August as a whole is shaping up to be cooler than average, Dale said. With one day left in the month, the average monthly temperature has been 70.5, which is 0.8 degrees below the historical monthly average of 71.3 degrees.
