AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
830 PM HST THU DEC 27 2012

.SYNOPSIS...
WINDS WILL CONTINUE TO WEAKEN AND TURN TO THE SOUTHEAST THROUGH THE
WEEKEND. EXPECT LOCAL LAND AND SEA BREEZES TO DEVELOP WITH SOME
CLOUDS AND LIGHT SHOWERS AFFECTING INTERIOR SECTIONS OF THE ISLANDS
DURING THE AFTERNOONS. A WEAKENING COLD FRONT WILL APPROACH THE
WESTERN PORTIONS OF THE STATE BY EARLY NEXT WEEK.

&&

.DISCUSSION...
WINDS ACROSS THE AREA ARE GRADUALLY VEERING TO THE SE AS THE HIGH
PRESSURE NE OF THE ISLANDS WEAKENS. MEANWHILE...A DEVELOPING JET
STREAM ACROSS THE CPAC WILL PUSH A NEARLY STATIONARY COLD FRONT
BOUNDARY TOWARDS THE NW PORTIONS OF THE ALOHA STATE DURING THE NEXT
COUPLE OF DAYS. THIS WILL FURTHER ERODE THE WESTERN EDGE OF THE
RIDGE TO THE NE OF THE ISLANDS AND BRING PERIODS OF LIGHT AND
VARIABLE WINDS THROUGH THE WEEKEND. LATEST HILO AND LIHUE SOUNDINGS
STILL SHOW PWATS AROUND 1 INCH...ALONG WITH INVERSIONS IN THE 6-8K
FT RANGE. THUS...MOISTURE WILL STILL REMAIN LIMITED WITH RELATIVELY
STABLE ATMOSPHERIC CONDITIONS THROUGH SUNDAY AND RETURNING LAND/SEA
BREEZE CIRCULATIONS.

SOME INTERIOR AND LEEWARD AREAS MAY SEE A BRIEF SHOWER OR TWO AS SEA
BREEZES PUSH INLAND EACH AFTERNOON. THEN CLEARING SKIES AND LIGHT
WINDS WILL PREVAIL ACROSS INTERIOR AREAS AT NIGHT AS GOOD
RADIATIONAL COOLING CONDITIONS DEVELOP.

MODEL GUIDANCE IS SHOWING BETTER CONSENSUS FOR THE BEGINNING OF NEXT
WEEK...WITH THE SFC FRONT REACHING KAUAI BY MONDAY AND CYCLOGENESIS
DEVELOPING FAR NORTH OF THE STATE. GFS RAPIDLY WEAKENS THE FRONT
OVER THE NW PORTIONS OF THE ALOHA STATE...WHILE ECMWF KEEPS IT A
LITTLE STRONGER AND BRINGS IT ALL THE WAY TO MAUI BEFORE FINALLY
BREAKING IT DOWN. REGARDLESS OF THE FINAL OUTCOME...CONSENSUS SHOWS
A DEFINITE FROPA ACROSS MUCH OF THE ISLANDS WITH INCREASING SHOWERS
FOR THE MON-TUE TIME FRAME. WINDS VEER TO THE N AND NE IN THE WAKE
OF THE FRONT...EVENTUALLY VEERING TO A MORE TYPICAL TRADE WIND
REGIME BY THE MIDDLE OF THE WEEK...ALONG WITH RE/ESTABLISHING HIGH
PRESSURE ACROSS THE AREA.

&&

.MARINE...
WITH THE CURRENT SWELL STILL PEAKING...THE HIGH SURF WARNINGS AND
ADVISORIES HAVE BEEN EXTENDED THROUGH FRIDAY EVENING. A SECOND
LARGER SWELL WILL ARRIVE LATE SATURDAY AND REMAIN IN PLACE THROUGH
EARLY NEXT WEEK.

A SMALL CRAFT ADVISORY IS NOW IN EFFECT FOR ALL COASTAL WATERS
EXCEPT MAALAEA BAY. WINDS HAVE DIMINISHED DURING THE AFTERNOON
HOURS...BUT SEAS WILL INCREASE AS THE LARGE NORTHWEST SWELL BUILDS.

&&

.AVIATION...
MVFR CEILINGS AND VISIBILITIES MAY BRIEFLY OCCUR WITH ISOLATED
SHOWERS OVER WINDWARD AND MAUKA AREAS. OTHERWISE...VFR CONDITIONS
WILL PREVAIL ACROSS THE STATE.

&&
