HAWAIIAN ISLANDS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
400 PM HST MON MAR 1 2004
.SYNOPSIS...
A LOW SOUTH OF KAUAI WILL BRING CLOUDS AND SHOWERS TO THE MAIN
HAWAIIAN ISLANDS THROUGH TUESDAY. THIS LOW WILL WEAKEN AND BE PUSHED
WESTWARD AS HIGH PRESSURE MOVES IN TO OUR NORTH AND TRADE WINDS
RETURN...BUT THE RETURNING TRADE FLOW WILL BE WET. EXPECT THE BULK
OF CLOUDS AND SHOWERS TO AFFECT WINDWARD AND MAUKA AREAS WEDNESDAY
AND THEREAFTER.
&&
.DISCUSSION...
COUNTERCLOCKWISE FLOW AROUND A LOW SOUTH OF KAUAI CONTINUES TO BRING
CLOUDS AND SHOWERS TO THE MAIN HAWAIIAN ISLANDS THIS AFTERNOON. MOST
OF THE SHOWERS ARE ORGANIZED INTO NORTH-TO-SOUTH BANDS FROM OAHU TO
MAUI. AFTERNOON SOUNDINGS SHOW THE BOUNDARY LAYER IS QUITE
MOIST...WITH ABOUT 1.5 INCHES OF PRECIPITABLE WATER NOTED AT HILO.
K-INDICES ARE HIGH...IN THE UPPER 20S...BUT 500 MB TEMPS ARE WARM AT
ABOUT MINUS 9 DEGREES C. IN OTHER WORDS...OUR AIRMASS IS MOIST BUT
ONLY MODERATELY UNSTABLE. THE OVERALL RESULT WILL LIKELY BE
SCATTERED TO NUMEROUS SHOWERS OVER THE CENTRAL ISLANDS BUT NO DEEP
CONVECTION NEEDED FOR THUNDERSTORMS. SATELLITE IMAGERY HINTS THAT
KAUAI AND THE BIG ISLAND WILL SEE FEWER SHOWERS...AT LEAST IN THE
NEAR TERM.
THE LOW WILL REMAIN IN PLACE FOR THE NEXT 24 HOURS OR SO...BUT IT
WILL WEAKEN AND OPEN INTO A TROUGH BY LATE TUESDAY. HIGH PRESSURE
MOVING EASTWARD ACROSS THE DATELINE NEAR 30N WILL STRENGTHEN TO 1035
MB AS IT PASSES NORTH OF THE ISLANDS WEDNESDAY. CENTERED NEAR 38N BY
THAT TIME...THIS HIGH WILL INDUCE A STRONG ENOUGH TRADE WIND FIELD
IN OUR AREA TO PUSH WHATEVER IS LEFT OF THE LOW WESTWARD BEYOND
160W.
OUR AIRMASS WILL REMAIN MOIST EVEN WHEN TRADES RETURN. LAYERED
CLOUDS AND SHOWERS ALONG A STATIONARY FRONT EAST OF THE BIG ISLAND
WILL BE PUSHED WESTWARD OVER THE STATE...MAKING THE RETURNING TRADE
FLOW WET AND SHOWERY INTO NEXT WEEKEND. WINDWARD AND MAUKA AREAS
WILL SEE THE BULK OF THESE TRADE SHOWERS...BUT 20 TO 25 MPH TRADE
WINDS BY THE WEEKEND MAY PUSH SHOWERS OVER LEEWARD AREAS AS WELL AT
TIMES.
