.DISCUSSION... High pressure remains settled in over much of the

forecast area today resulting in mild and dry conditions with 

northwest flow persisting at the burn site. Despite modest mixing

heights, elevated transport winds will compensate for this

bringing clearing indices just above 500 this afternoon. Tomorrow

afternoon, transport winds begin to lighten with more stable air 

pushing in resulting in lower-end clearing indices.
