AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
830 PM HST FRI AUG 29 2008
.SYNOPSIS...
HIGH PRESSURE NORTH OF THE ISLANDS WILL MAINTAIN MODERATE TRADE 
WINDS THROUGH THE HOLIDAY WEEKEND...AND INTO NEXT WEEK. TRADE 
SHOWERS WILL INCREASE TONIGHT FOR WINDWARD AND MAUKA 
LOCATIONS...THEN DIMINISH SLIGHTLY SATURDAY AND SUNDAY. TRADE 
SHOWERS MAY INCREASE AGAIN ON LABOR DAY AND TUESDAY AS 
AN UPPER LOW PASSES OVER THE ISLANDS. THE TRADES WILL CARRY A FEW 
SHOWERS TO THE LEEWARD AREAS OF THE SMALLER ISLANDS AT TIMES. 
&&
.DISCUSSION...
AREA OF LOW CLOUDS PASSING THE ISLANDS THIS EVENING...BRINGING 
SHOWERS TO WINDWARD AND MOUNTAIN SECTIONS. LATEST RAINFALL REPORT 
FROM AROUND THE STATE DID NOT SHOW MUCH. THAT IS NOT SURPRISING 
SINCE THE SHOWERS ARE MOVING SWIFTLY UNDER THE MODERATE TRADE 
WINDS. DO EXPECT MORE PASSING CLOUDS AND SHOWERS TO AFFECT THE 
ISLANDS THROUGH THE REST OF THE EVENING INTO SATURDAY MORNING.
HIGH PRESSURE THAT IS RESPONSIBLE FOR THE TRADE WINDS WILL REMAIN 
FAR NORTH OF OUR AREA. LATEST FORECAST CHARTS INDICATE THE HIGH 
PRESSURE WILL PREVAIL NORTH OF THE ISLANDS THROUGH THE REST OF THE 
WEEKEND...THROUGH NEXT WEEK. HENCE EXPECT TRADE WIND WEATHER TO 
REIGN OVER THE AREA THROUGH THE PERIOD. THERE IS AN UPPER LEVEL 
TROUGH OF LOW PRESSURE IN OUR VICINITY. FORECAST CHARTS INDICATE 
THIS TROUGH WILL REMAIN CLOSE TO THE ISLANDS THROUGH EARLY PART OF 
NEXT WEEK. THE CLOSE PROXIMITY OF THIS TROUGH LEADS TO THE AIR MASS 
OUR VICINITY BEING SLIGHTLY UNSTABLE...ALLOWING MORE CLOUDS TO 
DEVELOP HIGHER WHICH MAY RESULT IN HEAVIER AS WELL AS MORE 
WIDESPREAD SHOWERS. ON THE OTHER HAND...MODERATE TRADE WINDS WILL 
KEEP THE SHOWERS MOVING RIGHT ALONG...THUS LIMITING THE AMOUNT ANY 
PLACE WILL SEE. HENCE LOOK FOR A LITTLE WETTER TRADE WIND WEATHER 
THROUGH THE HOLIDAY WEEKEND INTO EARLY NEXT WEEK.
LATEST FORECAST CHARTS STILL INDICATE AN UPPER RIDGE IS TO BUILD 
ACROSS THE ISLANDS FOR THE LATER HALF OF NEXT WEEK. LOOK FOR DRIER 
TRADE WIND WEATHER TO RETURN THEN.
&&
.MARINE...
WINDS IN THE WIND SENSITIVE MARINE ZONES ARE EXPECTED TO REMAIN 
JUST BELOW SMALL CRAFT CRITERIA TONIGHT. NOT MUCH SIGNIFICANT SWELL 
ARE EXPECTED FOR THE NEXT SEVERAL DAYS.
&&
.HFO WATCHES/WARNINGS/ADVISORIES...
NONE.
