.SYNOPSIS...
THE TRADE WINDS WILL LAST THROUGH THE WEEK...THANKS TO A HIGH
PRESSURE RIDGE TO THE NORTH. CLOUDS AND SHOWERS WILL BE SPARSE...
FAVORING WINDWARD AND MAUKA SECTIONS.

&&

.DISCUSSION...
THE TROUGH ALOFT AND THE AREA OF LOW LEVEL CONVERGENCE THAT BROUGHT
THUNDER AND RAIN TO THE SMALLER ISLANDS YESTERDAY AND LAST NIGHT
HAVE MOVED NORTHEAST OF THE BIG ISLAND. MODELS KEEP BOTH FEATURES
EAST AND NORTHEAST OF THE STATE...THEREBY ENDING THE THREAT OF
SEVERE WEATHER. THE COLD FRONT/SHEARLINE...THAT WAS NEVER ALL THAT
STRONG...IS NO LONGER IDENTIFIABLE OVER THE STATE.

THE FORECAST CALLS FOR TRADE WIND WEATHER THIS WEEK...THANKS TO A
SURFACE HIGH BUILDING TO OUR NORTH. THIS MARKS A MAJOR CHANGE IN THE
WEATHER PATTERN FROM THE WEAK RIDGE OVERHEAD AND LIGHT WINDS OF THE
LAST FEW WEEKS TO THE MORE NORMAL HIGH PRESSURE TO THE NORTH AND
TRADE WINDS OVERHEAD. BY WEDNESDAY...THE HIGH WILL HAVE MOVED FAR
NORTHEAST OF THE ISLANDS...LEAVING BEHIND A NORTHEAST TO SOUTHWEST
RIDGE TO OUR NORTH. THE RIDGE WILL MAINTAIN LIGHT TO MODERATE TRADES.

THE DRY WEATHER IS NOT AN ABSOLUTE CERTAINTY HOWEVER...AS THERE IS
ANOTHER SHORTWAVE TROUGH ALOFT ABOUT 600 MILES WEST NORTHWEST OF
KAUAI. THE TROUGH IS EXPECTED TO PASS OVER OR NEAR THE STATE...BUT
REMAIN SEPARATED FROM THE LOW LEVEL TRADE FLOW. BUT...IT BEARS
WATCHING SIMPLY BECAUSE OF ITS CLOSE PROXIMITY.

&&

.MARINE...
THE PRESENT NORTHWEST SWELL WILL SLOWLY LOWER OVERNIGHT...WITH SURF
PROBABLY DROPPING BELOW ADVISORY LEVELS TUESDAY MORNING. THE NEXT
NORTHWEST SWELL IS EXPECTED TO REACH US LATE THURSDAY AND PEAK
FRIDAY. WARNING-LEVEL SURF IS A DISTINCT POSSIBILITY.

&&

.HFO WATCHES/WARNINGS/ADVISORIES...
HIGH SURF ADVISORY FOR NORTHWEST SWELL.
SMALL CRAFT ADVISORY FOR NORTHWEST SWELL.
