The National Weather Service has issued a dense fog advisory for the Tri-Cities and has extended the air stagnation advisory through 10 a.m. Tuesday.

However, the end to the inversion over the Mid-Columbia and persistent fog may be in sight. The weather service predicts that a change in the weather pattern could bring some precipitation and an end to stagnant conditions Wednesday.

But until then, expect dense or patchy fog in the Mid-Columbia, possibly freezing on roadways overnight.
