PERIODS OF HEAVY SHOWERS WILL CONTINUE FOR KAUAI AND OAHU DURING THE NEXT COUPLE OF DAYS AS A BAND OF MOISTURE LINGERS ACROSS THE WESTERN END OF THE STATE. THUNDERSTORMS ARE ALSO EXPECTED ACROSS THIS AREA...WITH SOME POTENTIALLY BECOMING STRONG NEAR KAUAI TODAY. THE REST OF THE STATE CAN EXPECT A CONVECTIVE PATTERN UNDER A SOUTHERLY LOW LEVEL FLOW...BRINGING THE GREATEST AMOUNT OF CLOUD COVER AND THE HIGHEST CHANCE OF SHOWERS DURING THE DAY. A MORE STABLE TRADE WIND REGIME WILL REBUILD OVER THE AREA LATE WEDNESDAY AND THURSDAY. && .DISCUSSION... WET AND UNSETTLED WEATHER IS IN STORE TODAY FOR KAUAI AND OAHU. A SLOW-MOVING COLD FRONT JUST NORTHWEST OF KAUAI IS MERGING WITH A BAND OF PERSISTENT PREFRONTAL MOISTURE DRAPED ACROSS KAUAI AND OAHU. THIS MOISTURE...WITH PRECIPITABLE WATER VALUES AROUND 1.75 INCHES... HAS BEEN FUELING SCATTERED HEAVY SHOWERS ACROSS OAHU SINCE LAST NIGHT...WHILE SHOWER AND THUNDERSTORM ACTIVITY ON KAUAI IS PICKING UP THIS MORNING. A SHORTWAVE ALOFT CLEARLY SEEN ON IR AND WATER VAPOR SATELLITE IMAGERY LESS THAN 200 HUNDRED MILES WEST OF KAUAI WILL PASS OVER THE WESTERN END OF THE STATE THROUGH THE DAY... TRIGGERING ANOTHER ROUND OF HEAVY SHOWERS AND THUNDERSTORMS. SOME OF THESE THUNDERSTORMS WILL LIKELY BECOME STRONG NEAR KAUAI...AND SEVERE THUNDERSTORMS REMAIN A POSSIBILITY. A FLASH FLOOD WATCH REMAINS IN EFFECT FOR KAUAI AND NIIHAU...AND ALTHOUGH OAHU WILL SEE HEAVY SHOWERS TODAY...THE DEEPEST MOISTURE SHOULD REMAIN FOCUSED NEARER TO KAUAI FOR A LONGER DURATION. THUS...OAHU IS NOT INCLUDED IN THE WATCH. WET WEATHER IS EXPECTED TO CONTINUE THROUGH TUESDAY AND POSSIBLY INTO WEDNESDAY AROUND KAUAI. THE BAND OF MOISTURE WILL SLOWLY RETREAT NORTHWARD TONIGHT AND TUESDAY...DECREASING SHOWER CHANCES ON OAHU WHILE KEEPING THE GARDEN ISLAND WET. ACROSS THE REST OF THE STATE...SOUTHEAST SLOPES OF THE BIG ISLAND WILL CONTINUE TO SQUEEZE OUT ADDITIONAL RAINFALL...WHILE MAUI COUNTY WILL SEE SOME SHOWERS MOVE UP FROM THE SOUTH. A CONVECTIVE PATTERN WILL OTHERWISE PREVAIL...LEADING TO INTERIOR CLOUDS AND SHOWERS DURING THE AFTERNOON. EXPECT THIS PATTERN TO HOLD THROUGH TUESDAY. A WIND ADVISORY REMAINS POSTED FOR THE BIG ISLAND SUMMITS THROUGH TONIGHT. AS THE SHORTWAVE ALOFT PASSES BY LATER TODAY...WESTERLY WINDS COULD CLIMB HIGHER...POSSIBLY TO WARNING LEVELS.

A INCREASINGLY STABLE TRADE WIND WEATHER REGIME WILL GRADUALLY REBUILD OVER THE STATE LATE WEDNESDAY AND THURSDAY. TRADES MAY REACH MODERATE STRENGTH ON FRIDAY WITH A SLIGHT DECLINE POSSIBLE DURING THE WEEKEND. && .MARINE...

LINGERING FRONTAL CLOUD BAND WILL BE THE FOCUS OF WEATHER DEGRADING MAINLY KAUAI AND OAHU TERMINALS. TEMPO MVFR AND ISOLATED IFR EXPECTED THROUGH TONIGHT OVER THE NORTHWEST PART OF THE HAWAIIAN ISLAND CHAIN. ISOLATED THUNDERSTORMS ARE ALSO EXPECTED TO DEVELOP DUE TO A SHORT WAVE TROUGH PASSING THROUGH TODAY AND TONIGHT. CURRENTLY ICING ALOFT LIMITED DUE TO LACK OF SUFFICIENT MOISTURE IN THE PREFERRED TEMPERATURE RANGE. BUT THAT COULD CHANGE LATER WITH THE SHORT WAVE APPROACHING. AIRMET FOR MOUNTAIN OBSCURATION EXPECTED TO CONTINUE FROM KAUAI TO LANAI THROUGH MOLOKAI NOT FULLY EXPERIENCING IT YET. ANY TURBULENCE IS EXPECTED TO BE ASSOCIATED WITH CONVECTION...MAINLY NEAR THUNDERSTORMS. && .HFO WATCHES/WARNINGS/ADVISORIES... FLASH FLOOD WATCH FOR KAUAI AND NIIHAU THROUGH 6 AM TUESDAY.
