DISCUSSION
AMPLE SUNSHINE TODAY WHICH WILL RESULT IN MIXING AND LIKELY
A DRYING OUT FOR THE AFTERNOON. THE MIXING SHOULD KICK IN BETWEEN 11 AM AND
NOON AND EXPECT SURFACE DEWPOINTS TO START TO DROP THEN. CURRENTLY LOOKING
AT LOW TO MID 30% FOR MIN HUMIDITIES, BUT SEE THE POTENTIAL TO DROP INTO
THE UPPER 20% IF THE MIXING IS MORE ROBUST. NOT A LOT OF WIND AT THE TOP
OF MIXED LAYER, SO NOT EXPECTING WINDS TO BE TOO GUSTY. GENERALLY LIGHT AND VARIABLE
UNTIL MIXING GETS GOING, WITH EAST MORE FAVORED (ALTHOUGH VALLEY
LOCATION COULD CAUSE A LITTLE CHANNELING). STILL, SUSTAINED SHOULD
HOLD UNDER 10 MPH.
