A stagnant weather pattern produced 3 consecutive days of dense fog across much of the region January 16-19, 2010.  High pressure brought light winds to the area so little in the way of mixing of the atmosphere occurred. A strong inversion, combined with some snow melt adding low level moisture, trapped widespread stratus and dense fog for several days in a row. Travel was slowed due to the fog but there were no reports of major delays or accidents on the highways.
