AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE HONOLULU HI
440 AM HST SUN JUL 26 2015

.UPDATE...
SURF ADVISORY FOR SOUTH FACING SHORES IS NOW IN EFFECT UNTIL 6 PM
HST MONDAY...ALONG WITH EXPECTED LARGER SURF HEIGHTS OF 10 TO 14
FEET TODAY.

&&

.SYNOPSIS...
WEAK TRADES WILL CONTINUE TODAY AND THROUGH MONDAY AS THE REMNANTS
OF FORMER TROPICAL CYCLONE ENRIQUE PASS TO THE NORTH OF THE ISLANDS.
THIS WILL RESULT IN GENERALLY WARM AND HUMID CONDITIONS...WITH SEA
BREEZES BRINGING SOME AFTERNOON SHOWERS OVER INTERIOR AND LEEWARD
AREAS. HOWEVER...THE TRADES SHOULD REMAIN STRONG ENOUGH TO KEEP A
FEW SHOWERS ACROSS WINDWARD SLOPES. A MORE TYPICAL TRADE WIND
WEATHER PATTERN WILL RETURN BY THE MIDDLE OF NEXT WEEK.

&&

.DISCUSSION...
A SFC HIGH PRESSURE SYSTEM WAS OBSERVED CENTERED FAR N OF THE MAIN
HAWAIIAN ISLANDS...WHILE A WEAK SFC TROUGH IS SLOWLY MOVING W JUST
TO THE N OF OAHU. MEANWHILE...THE REMNANTS OF FORMER TROPICAL
CYCLONE ENRIQUE ARE LOCATED ABOUT 660 MILES NE OF THE BIG ISLAND AND
GRADUALLY MOVING W TOWARDS THE AREA. THE PRESENCE OF THE TROUGH AND
THE PASSAGE OF THE REMNANTS OF ENRIQUE WILL KEEP DISRUPTING THE
TRADE WIND FLOW ACROSS THE ISLANDS TODAY AND MOST LIKELY THROUGH
LATE MON.

A FEW PASSING SHOWERS HAVE BEEN DEVELOPING DURING THE OVERNIGHT
HOURS OVER WINDWARD AREAS OF OAHU AND KAUAI...WITH RADAR DATA
DEPICTING ONLY SMALL/CELLULAR TYPE SHOWERS WITH NO SIGNIFICANT
ASSOCIATED RAIN. THE ONLY EXCEPTION HAS BEEN THE WINDWARD AND SE
SLOPES OF THE BIG ISLAND WHERE A LARGER FIELD OF SHOWERS...ARRANGED
MAINLY IN NARROW BANDS...HAVE BEEN STREAMING FROM THE COASTAL
WATERS. AS BEFORE...RADAR DATA HAS SHOWN NO SIGNIFICANT RAINFALL
WITH ANY OF THESE FEATURES. HOWEVER...12Z SOUNDING DATA FROM HILO
AND LIHUE SHOW WEAKENING AND HIGHER INVERSIONS...BETWEEN 10 TO 11
THOUSAND FEET...ALONG WITH INCREASING PWATS UP TO 1.6 INCHES IN THE
HILO SOUNDING. THUS...CONDITIONS SHOULD BECOME MORE CONDUCIVE FOR
INCREASED SHOWER ACTIVITY ACROSS THE ISLAND CHAIN THROUGH THE NEXT
COUPLE OF DAYS.

FOR TODAY...LATEST LOCAL WRF MODEL CONTINUES TO SUGGEST MORE
WIDESPREAD AFTERNOON SEABREEZE ACTIVITY WITH GREATER CLOUD BUILDUPS
AND SHOWERS. THIS SYNOPTIC SETUP WILL BE REINFORCED BY THE PASSAGE
OF THE REMNANTS OF ENRIQUE...FURTHER WEAKENING THE TRADES AND
SUPPORTING SEABREEZES AND SHOWERS THROUGH MON. MEANWHILE...WINDWARD
AND MOUNTAIN AREAS WILL ALSO EXPERIENCE SOME CLOUDS AND SHOWERS
DURING THE NEXT COUPLE OF DAYS SINCE THE WEAK TRADES SHOULD STILL
BRING ENOUGH MOISTURE OVER THE WINDWARD SLOPES OF THE SMALLER
ISLANDS.

BY TUE...THE SYNOPTIC PATTERN WILL BEGIN TRANSITIONING TO A MORE
TRADE WIND WEATHER REGIME AS THE REMNANTS OF ENRIQUE CLEAR THE AREA.
THIS WILL ALLOW FOR PRESSURE GRADIENTS TO BECOME STRONGER AS THE SFC
HIGH N OF THE ISLANDS INTENSIFIES. MODELS ALSO SHOW AN UPPER LEVEL
RIDGE DEVELOPING OVER THE ISLANDS FROM THE SE...WITH STRONGER
INVERSIONS PROVIDING FOR A MORE STABLE AIRMASS ACROSS THE STATE.
THIS TRADE PATTERN SHOULD CONTINUE THROUGH THE REMAINDER OF THE WORK
WEEK.

&&

.AVIATION...
A WEAK TROUGH OF LOW PRESSURE WILL PUSH BY TO THE NORTH OF THE
ISLANDS TODAY...KEEPING A LIGHT WIND REGIME IN PLACE ACROSS THE
STATE THROUGH TONIGHT. AS A RESULT...OVERNIGHT LAND BREEZES AND
DAYTIME SEA BREEZES ARE EXPECTED AT MANY OF THE TAF SITES. EXPECT
CLOUDS AND SHOWERS TO IMPACT MAINLY INTERIOR AND LEEWARD AREAS
TODAY...ALTHOUGH THE LIGHT TRADE WIND FLOW SHOULD BE ENOUGH TO BRING
A FEW SHOWERS ONSHORE IN WINDWARD LOCATIONS AS WELL. PHNY WILL
LIKELY SEE MVFR CIGS AFTER 20Z TODAY...ELSEWHERE VFR CONDITIONS ARE
EXPECTED TO PREVAIL OUTSIDE OF ANY ISOLATED SHOWERS. NO AIRMETS ARE
CURRENTLY IN EFFECT.

&&

.MARINE...
A MODERATE TO LARGE SOUTH SOUTHWEST SWELL WILL CONTINUE TO KEEP
SURF AT ADVISORY LEVELS ALONG ALL SOUTH FACING SHORES THROUGH MONDAY
BEFORE STARTING TO GRADUALLY SUBSIDE. BASED ON LATEST BUOY
REPORTS...THE ADVISORY HAS BEEN EXTENDED UNTIL 6 PM HST MONDAY.
MODELS SHOW ANOTHER PULSE OF ENERGY REACHING THE ISLANDS ON MONDAY
AND BLENDING IN WITH THE EARLIER SOUTH SWELL. THUS...THE SURF ALONG
SOUTH FACING SHORES IS EXPECTED TO REMAIN ELEVATED THROUGH EARLY
NEXT WEEK.

&&

.HFO WATCHES/WARNINGS/ADVISORIES...
HIGH SURF ADVISORY NOW UNTIL 6 PM HST MONDAY FOR SOUTH FACING SHORES
OF ALL ISLANDS.
