AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE HONOLULU HI 830 PM HST THU JUL 31 2008 .SYNOPSIS... TRADE WINDS WILL CONTINUE TO BLOW ACROSS THE MAIN HAWAIIAN ISLANDS THROUGH THE FORECAST PERIOD. WIND SPEEDS WILL DECREASE FRIDAY AND INTO THE WEEKEND AS TROUGHING ALOFT WEAKENS THE GOVERNING SURFACE RIDGE TO OUR NORTH. TRADE WIND SHOWERS MAY INCREASE A BIT SUNDAY AND MONDAY WHEN REMNANT MOISTURE FROM A FORMER TROPICAL SYSTEM PASSES. && .DISCUSSION... CLOUD COVER IS SCARCE EAST OF THE ISLANDS TO 150W...WITH CLOUD COVER BECOMING BROKEN TO OVERCAST EAST OF 145W. THEREFORE...IN SPITE OF MILDLY UNSTABLE CONDITIONS DEPICTED IN AFTERNOON SOUNDINGS...WE EXPECT VERY LITTLE PRECIPITATION OVERNIGHT AND THROUGH MOST OF FRIDAY. BY SUNDAY...THE REMNANT MOISTURE FIELD FROM AN OLD TROPICAL SYSTEM WILL REACH THE SOUTHERN ISLANDS...POSSIBLY INCREASING TRADE WIND SHOWER COVERAGE. SATELLITE LOOPS SHOW THIS MOISTURE IN THE FORM OF WARM-TOPPED SHALLOW LOW CLOUDS SOUTH AND EAST OF A LINE FROM 28N140W TO 25N150W TO 20N145W...MORE THAN 600 MILES EAST OF THE ISLANDS. GFS SHOWS THIS AREA OF INCREASED MOISTURE WILL SHRINK AS IT GRAZES WINDWARD PORTIONS OF THE ISLANDS SUNDAY AND MONDAY. AT MOST...WE EXPECT AN INCREASE IN TRADE WIND SHOWER COVERAGE...EXTENDING FARTHER SOUTHWEST ACROSS KAU DISTRICT ON THE BIG ISLAND FOR EXAMPLE. THE 1028 MB HIGH FAR NORTHWEST OF THE MAIN HAWAIIAN ISLANDS CONTINUES DRIFTING TOWARD THE WEST. THE RIDGE EXTENDING EAST FROM THE HIGH WILL WEAKEN AS THE UPPER TROUGH NORTH OF THE ISLANDS...THE SAME UPPER TROUGH RESPONSIBLE FOR OUR MILDLY UNSTABLE AIRMASS...DIGS FARTHER TO THE SOUTHWEST. THE PRESSURE GRADIENT ASSOCIATED WITH THE WEAKENED SURFACE RIDGE WILL LIKELY ONLY SUPPORT 10 TO 15 MPH TRADE WINDS ACROSS THE MAIN ISLANDS LATE FRIDAY THROUGH MONDAY. BY TUESDAY...THE UPPER TROUGH WILL FILL...ALLOWING THE SURFACE RIDGE TO REGAIN STRENGTH AND INDUCE STRONGER TRADE WINDS. IN SHORT...WE EXPECT A PERIOD OF DECREASED TRADE WINDS BUT INCREASED MOISTURE THIS WEEKEND...THEN A RETURN TO DRIER AND WINDIER CONDITIONS TUESDAY AND BEYOND. && .HFO WATCHES/WARNINGS/ADVISORIES...
