HIGH PRESSURE WILL ADVANCE ACROSS THE REGION WITH THE MAIN AXIS
PASSING OVERHEAD WEDNESDAY. SEASONABLE HIGHS IN THE 70S ARE EXPECTED
AS IT PASSES. STRONG MIXING TODAY AND POSSIBLY WED WILL ALLOW
POCKETS OF LOWER AFTERNOON RH VALUES AS WELL AS SOMEWHAT GUSTIER
WINDS. GIVEN GREEN-UP ALREADY FINISHED AND OVERALL CONDITIONS STILL
SOMEWHAT MOIST THE RISK FOR FIRE WEATHER CONCERNS LOW.
LOW LEVEL TEMPERATURES WARM ON THURSDAY AND FRIDAY WITH HIGHS WELL
INTO THE 80S. MOISTURE WILL TAKE A BIT OF TIME TO GET HERE, WITH MID
TO UPPER 50 DEWPOINTS INTO FRIDAY BEFORE MUGGY MID 60 DEWPOINTS
ARRIVE FOR THE WEEKEND AND INTO NEXT WEEK. THE UPPER LEVEL FLOW
FLATTENS AND ALLOWS A SERIES OF WEAK DISTURBANCES TO MOVE
THROUGH THE REGION AS THE BETTER MOISTURE ARRIVES. WHILE SOME
CONVECTION COULD OCCUR DIURNALLY AS EARLY AS FRIDAY AFTERNOON,
BETTER CHANCES SEEM TO RESIDE WITH SATURDAY AND POSSIBLY INTO
SUNDAY AS A MORE PRONOUNCED WAVE ARRIVES. MED RANGE MODELS VARY
ON TIMING AND STRENGTH, LEADING TO LOW CONFIDENCE AT THIS POINT.
WHILE THE HIGHEST POPS ARE SATURDAY. THESE ARE SUBJECT TO
CHANGE. ADDITIONAL CHANCES FOR CONVECTION EXIST INTO NEXT WEEK,
BUT WARRANT NO MORE THAN SLGT CHC TO CHC.
