NATIONAL WEATHER SERVICE HONOLULU HI
4 PM HST MON MAR 15 2004

.SYNOPSIS...
HEAVY SHOWERS AND THUNDERSTORMS REMAIN IN THE FORECAST FOR THE BIG
ISLAND THROUGH TUESSDAY. A SHEARLINE WILL KEEP CONDITIONS WET AND
UNSTABLE THERE THROUGH THE MIDDLE OF THE WORK WEEK. THE SMALLER
ISLANDS WILL SEE DRY WEATHER AND BRISK TRADE WINDS.

&&

.DISCUSSION...
A SHEARLINE ORIENTED NORTHEAST TO SOUTHWEST OVER THE BIG ISLAND WILL
PROBABLY TRIGGER HEAVY SHOWERS AND ISOLATED THUNDERSTORMS FOR AT
LEAST ONE MORE DAY. THE HEAVY RAIN WILL FAVOR THE WINDWARD OR HILO
SIDE OF THE ISLAND BECAUSE OF THE PREVAILING NORTHEAST WINDS. THE
LEEWARD OR KONA SIDE WILL FOLLOW A DIURNAL CONVECTIVE PATTERN WITH
DAYTIME SEA BREEZES WITH SHOWERS AND THUNDERSTORMS...AND NIGHTTIME
LAND BREEZES WITH CLEARING SKIES.

FOR THE SMALLER ISLANDS...STRATOCUMULUS CLOUDS WILL PROBABLY STACK
UP OVER WINDWARD SECTIONS LEAVING LEEWARD SECTIONS UNDER MOSTLY
CLEAR SKIES. LITTLE OR NO SHOWERS ARE EXPECTED WITH THE EXCEPTION
OF WINDWARD MAUI BECAUSE A LOW SUBSIDENCE INVERSION NEAR 5000 FEET.
THE NORTHEAST WINDS ARE FORECAST TO SLACKEN SLIGHTLY BY WEDNESDAY AS
THE PRESSURE GRADIENT BETWEEN THE ISLANDS AND A SURFACE HIGH TO THE
NORTHWEST WEAKENS.

PROGS SAY THAT A LOW NORTHEAST OF HAWAII WILL REMAIN STATIONARY
THROUGH  THURSDAY...ALLOWING THE SHEARLINE TO BE STATIONARY OVER
OR JUST SOUTH OF THE BIG ISLAND. THE THREAT OF HEAVY SHOWERS AND
THUNDERSTORMS ON THE BIG ISLAND WILL REMAIN IN THE FORECAST AS LONG
AS THE SHEARLINE REMAINS NEARBY.

THE 1030 MB HIGH NORTHWEST OF THE ISLANDS HAS BEEN BLOCKED FROM
MOVING EASTWARD BY THE LOW. THE STATIC PATTERN WILL CONTINUE UNTIL
FRIDAY...WHEN THE LOW IS FORECAST TO LIFT OUT TO THE NORTHEAST. THE
HIGH WILL HAVE LIFTED NORTHWARD AS WELL...BUT MODELS SHOW AN
ASSOCIATED RIDGE WILL FILL IN SOUTHEASTWARD BETWEEN THE LOW AND THE
HAWAIIAN ISLANDS AS THE LOW MOVES AWAY. BECAUSE THE RETURNING RIDGE
WILL ONLY BE AN EXTENSION OF A STRONG HIGH NORTH OF 40N...THE
INDUCED TRADES WILL NOT AS STRONG AS THEY ARE NOW.

IN SUMMARY...THE FORECAST CALLS FOR CONTINUED BOUTS OF HEAVY SHOWERS
AND THUNDERSTORMS FOR THE BIG ISLAND AT LEAST THROUGH TUESDAY...
WHILE THE SMALLER ISLANDS WILL SEE DRYER CONDITIONS.
