.DISCUSSION...GUSTY NORTHEASTERLY WINDS ON SITE THIS MORNING EVIDENT OF
A FAIRLY STRONG LOW LEVEL INVERSION ENHANCING DIURNAL DRAINAGE WINDS.
THAT SAID...SOUTHERLY ASPECT OF SITE COMBINED WITH A NET INCREASE IN
SOUTHWESTERLY WINDS ALOFT COME MIDDAY WILL ALLOW THE LOW LEVEL INVERSION
TO MIX OUT BETWEEN 1030 AND 1100 THIS MORNING. EXPECT CLEARING INDICES
TO JUMP TO BURNABLE LEVELS RAPIDLY THEREAFTER. ANTICIPATE YET ANOTHER
DIURNAL INVERSION WILL BEGIN DEVELOPING AFTER 2000 THIS EVENING...BUT
COMBINATION OF A FURTHER NET INCREASE OF SOUTHWESTERLY FLOW ALOFT ON
SUNDAY AND GRADUAL DESTABILIZATION OF THE MID LEVELS WILL YIELD EVEN
BETTER CONDITIONS BY 1000 SUNDAY. CALL WITH QUESTIONS...
