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 TODAY. ISLAND TRADES SHOULD
INCREASE TO MODERATE TO BRISK LEVELS OVER THE NEXT FEW DAYS AND
LINGER THROUGH NEXT WEEKEND INTO NEXT WEEK AS STRONG 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 SOUTHEAST OF THE STATE THROUGH THE WEEKEND, 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 AS UPPER TROUGHING GRADUALLY WORKS BACK OVER
THE STATE ALONG WITH SURFACE FLOW RESPONSE, ALBEIT WITH SOME
UNCERTAINTY GIVEN THE TRANSITION IS AT THESE LONGER TIME FRAMES.
