.DISCUSSION...
LIGHT AND VARIABLE WINDS WILL PREVAIL THROUGH THURSDAY. EXPECT
DAYTIME SEA BREEZES AND NIGHTTIME LAND BREEZES. CLEARING SKIES AT
NIGHT WILL ALLOW RADIATIONAL COOLING TO PRODUCE A SURFACE BASED
NOCTURNAL INVERSION EXTENDING UP TO ABOUT 500 FEET. THIS WILL
LIKELY TRAP HIGHER CONCENTRATIONS OF VOG IN SOME AREAS. DAYTIME
MIXING WILL ELIMINATE THE INVERSION ALLOWING THE VOG TO SCOUR OUT
OF THESE DENSE POCKETS. PRECIPITATION IS EXPECTED TO REMAIN LOW
WITH ONLY ISOLATED LIGHT SHOWERS ALONG THE SOUTHEAST BIG ISLAND
SLOPES.
