HAWAIIAN ISLANDS FORECAST DISCUSSION NATIONAL WEATHER SERVICE HONOLULU HI 400 AM HST THU FEB 3 2005 .SYNOPSIS... A SURFACE TROUGH OVER THE STATE...WITH A TROUGH ALOFT NEAR KAUAI. THIS WILL KEEP USETTLED WEATHER OVER THE STATE TODAY...BUT WITH SOME IMPROVEMENT EXPECTED TONIGHT AND FRIDAY AS THE TROUGHS MOVE EASTWARD AND ALLOW DRIER AIR TO FILTER IN OVER THE ISLANDS. MORE SUNSHINE AND DRIER WEATHER SHOULD PREVAIL OVER THE WEEKEND AND THROUGH MUCH OF NEXT WEEK AS RIDGING ALOFT REPLACES THE SLOW MOVING TROUGH THAT HAS KEPT OUR SKIES CLOUDY FOR MUCH OF THIS WEEK. && .DISCUSSION... WEAK LOW PRESSURE NEAR 19N 160W IS AT THE BASE OF AN ELONGATED SURFACE TROUGH THAT LIES OVER THE CENTRAL MAIN HAWAIIAN ISLANDS COMBINED WITH A SHARP TROUGH OF LOW PRESSURE ALOFT ORIENTED NORTH NORTHEAST TO SOUTH SOUTHWEST NEAR KAUAI IS KEEPING A THICK OVERCAST LAYER OF MID AND HIGH CLOUD OVER THE STATE. AREAS OF LIGHT RAIN HAVE BEEN FALLING FROM THIS OVERCAST...WITH ISOLATED HEAVY SHOWERS AND A FEW STRONG THUNDERSTORMS MOVING AROUND UNDERNEATH THIS CLOUD MASS...MAINLY OVER OPEN OCEAN WATERS. WINDS ACROSS THE STATE REMAIN LIGHT UNDER THE INFLUENCE OF THE SURFACE TROUGH...BUT AT CLOUD LEVEL RADAR IS SHOWING SHOWER CELLS MOVING FROM THE SOUTHWEST FROM WELL SOUTH OF THE ISLANDS UP OVER EASTERN OAHU...MAUI COUNTY AND THE BIG ISLAND...AND FROM THE NORTHEAST OVER WEST OAHU AND KAUAI. CELLS ARE NEARLY STATIONARY TO THE NORTHEAST OF MAUI COUNTY. THE LOW PRESSURE CENTER SOUTH OF KAUAII HAS BEEN MOVING TOWARD THE NORTHEAST AT NEARLY 30 MPH THROUGH THE NIGHT AND SHOULD PASS OVER OAHU LATER THIS MORNING. ONCE THIS LOW HAS PASSED NORTH OF THE ISLANDS WE SHOULD SEE SOME PARTIAL CLEARING. THE AIRMASS REMAINS UNSTABLE HOWEVER...AND WITH ENOUGH SUNSHINE HEATING UP THE ISLANDS...THERE MAY BE SOME AFTERNOON SHOWERS AND EVEN A POSSIBLE THUNDERSTORM. BUT WITH THE BULK OF THE HIGH CLOUD MOVING NORTHWARD WITH THIS SURFACE IMPULSE...EXPECT PARTIAL CLEARING TONIGHT AND ON FRIDAY...WITH EVEN MORE SUNSHINE EXPECTED FOR THE WEEKEND. WITH LIGHT NORTHEAST SURFACE WINDS HOWEVER...WOULD ALLOW FOR THE POSSIBILITY OF A FEW WINDWARD AND MAUKA SHOWERS...AND POSSIBLY SOME AFTERNOON CONVECTIVE SHOWERS AS SEA BREEZES CLASH WITH THE LIGHT TRADE WINDS. AT THIS TIME THE GFS MODEL IS SUGGESTING A RETURN OF NORTHEAST...OR TRADE DIRECTION WINDS...NEXT WEEK AS RIDGING REPLACES THE CURRENT SHARP TROUGH ALOFT. BUT THIS MODEL HAS BEEN TRYING TO BRING TRADE WINDS BACK FOR AT LEAST A COUPLE OF WEEKS...UNSUCCESSFULLY...SO WILL KEEP THESE NORTHEAST WINDS LIGHT TO MODERATE AND ADOPT A MORE WAIT AND SEE ATTITUDE ON THIS FOR THE MOMENT. && .HFO WATCHES/WARNINGS/ADVISORIES... FLASH FLOOD WATCH FOR NIIHAU AND KAUAI EXTENDED THROUGH TODAY. FLASH FLOOD WATCH FOR OAHU MAUI MOLOKAI LANAI KAHOOLAWE AND THE BIG ISLAND THROUGH TODAY. WINTER STORM WARNING FOR BIG ISLAND SUMMITS THROUGH TODAY. && FARRELL
