What happened
The episode as NWS MKX wrote it up.
Dense fog developed overnight and lowered visibilities to 1/8 to 1/4 mile. Morning commuters had to slow down, and area newspapers reported several vehicle accidents. The dense fog was the result of light winds and plenty of low-level moisture due to some snowmelt in the wake of 3 to 6 inches that fell the previous day.
