GUIDANCE GENERALLY AGREES THAT UPPER RIDGING OVER THE STATE OFFERS
A MORE STABLE PATTERN WITH TYPICAL TRADE FLOW AND MODEST PASSING
SHOWERS FAVORING WINDWARD TERRAIN OVER THE NEXT FEW DAYS.
AMPLIFIED MID-LATITUDE UPPER TROUGH AND SURFACE SYSTEM PASSAGE
WELL TO THE NORTH OF THE STATE COULD BRING ANOTHER
WEAKENING/STALLING TRAILING FRONT TOWARD THE ISLANDS BY MID-LATE
WEEK. ISLAND TRADES MAY INCREASE TO MODERATE TO BRISK LEVELS AND
LINGER THROUGH NEXT WEEKEND AS POST-FRONTAL HIGH PRESSURE BRIDGES
TO THE NORTH THEN NORTHEAST OF THE STATE. IN THIS PATTERN, THE
BULK OF UPPER TROUGHING AND DEEPEST MOISTURE REMAINS JUST TO THE
SOUTH OF THE STATE, BUT RENEWED TRADES SHOULD BE ABLE TO TAP
ENOUGH FOR PERIODIC SHOWERS OVER FAVORED WINDWARD TERRAIN. THE BIG
ISLAND SEEMINGLY HAS THE BEST POTENTIAL FOR SOME HEAVIER DOWNPOURS
INTO EARLY NEXT WEEK GIVEN DEEPEST MOISTURE POTENTIAL.
