AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
400 AM HST SAT MAR 14 2009

.SYNOPSIS...
A LOW FAR NORTH OF THE ISLANDS WILL MOVE CLOSE TO KAUAI OVER THE
NEXT COUPLE OF DAYS AND SLOWLY DISSIPATE IN THE VICINITY EARLY
NEXT WEEK. IT MAY BRING SOME UNSETTLED WEATHER TO THE ISLANDS TODAY.
A TROUGH OF LOW PRESSURE WILL LINGER NEAR THE ISLANDS THROUGH THE
MIDDLE OF NEXT WEEK...KEEPING WINDS LIGHTER.

&&

.DISCUSSION...
WEATHER CERTAINLY GOT MUCH MORE ACTIVE THIS EARLY MORNING FOR THE
WESTERN ISLANDS ...AS RADAR IMAGERY SHOWS STRONGER RETURNS FROM RAIN
CLOUDS IN THE OAHU VICINITY. LOW CLOUDS ASSOCIATED WITH THE LOW
NORTH OF THE ISLANDS PERSIST OVER THE WESTERN ISLANDS SINCE LAST
NIGHT. MORNING SOUNDING FROM LIHUE INDICATED THE AIR MASS HAS
BECOME UNSTABLE WITH NO INVERSION AND DEEP MOISTURE EXTENDING TO
NEAR 14K FT...WHILE HILO MORNING SOUNDING INDICATED A DRIER AIR MASS
WITH MARGINAL STABILITY. THUS EXPECT UNSETTLED WEATHER TO AFFECT THE
WESTERN MAIN HAWAIIAN ISLANDS FROM NIIHAU TO MAUI TODAY...WITH
LOCALLY HEAVY SHOWERS AS WELL AS A SLIGHT CHANCE OF THUNDERSTORMS.
BIG ISLAND WEATHER SHOULD SEE LESS ACTIVITIES...AS IT IS FURTHEST
FROM THE LOW.

STRONG WINDS PREVAIL AT THE SUMMITS OF MAUNA KEA AND MAUNA LOA EARLY
THIS MORNING. FORECAST CHARTS INDICATE THESE STRONG WINDS WILL
PERSIST AND MAY INCREASE AT TIMES THROUGH THE WEEKEND INTO EARLY
NEXT WEEK. HENCE A WIND ADVISORY REMAINS IN EFFECT FOR THE SUMMITS
OF THE BIG ISLAND THROUGH EARLY SUNDAY AT TIME.

THIS LOW IS STILL EXPECTED TO MOVE NEAR KAUAI BY SUNDAY AND SLOWLY
WEAKEN. A SURFACE LOW PRESSURE TROUGH IS EXPECTED TO PERSIST NEAR
THE ISLANDS AT LEAST THROUGH THE MIDDLE OF THE NEXT WEEK. WINDS
WILL BE LIGHT WITH LAND AND SEA BREEZES TO BECOME MORE PROMINENT
THEN. AIR MASS WILL REMAIN SOMEWHAT UNSTABLE NEXT WEEK...THUS EXPECT
THE CONVECTIVE TYPE WEATHER REGIME NEXT WEEK TO BRING SHOWERS TO
THE INTERIOR AND WINDWARD SECTIONS DURING AFTERNOON AND EVENING
HOURS...WITH SOME CLEARING OVERNIGHTS.

LOOKS LIKE THE TRADES MAY FINALLY RETURN TOWARDS NEXT WEEKEND. IN
FACT...LATEST FORECAST CHARTS INDICATE RATHER STRONG TRADE WINDS TO
DEVELOP OVER THE ISLANDS...AS THE DIFFERENT LONG RANGE MODELS SHOW
SIMILAR TREND.
