THIS CLOUD AREA APPEARS TO HAVE A WEAK SURFACE REFLECTION...WITH A LOW-LEVEL TROUGH AXIS LOCATED ABOUT 50 MILES NORTHEAST OF OAHU. WITH THE TROUGH IN THIS LOCATION...LOCALLY BREEZY NORTH-NORTHEAST WINDS ARE OVER KAUAI AND ADJACENT WATERS...WHERE LOW CLOUDS ARE MOVING SOUTHWEST AT 15 TO 20 MPH. THE LOW LEVEL FLOW NEAR OAHU IS ALSO TOWARD THE SOUTHWEST...AND THE LOW LEVEL FLOW SOUTH OF THE BIG ISLAND IS TOWARD THE WEST...ALTHOUGH LOW CLOUD MOTIONS INDICATE A LIGHT FLOW. A WEAK AND SMALL LOW LEVEL CLOUD CIRCULATION OVER WATERS ABOUT 100 MILES EAST NORTHEAST OF WINDWARD MAUI IS AFFECTING THE LOW LEVEL FLOW IN THAT AREA...WITH RELATIVELY LIGHT AND VARIABLE WINDS OVER WATERS NEAR MAUI AND THE BIG ISLAND. SKIES ARE PARTLY CLOUDY OVER THE BULK OF KAUAI...WITH CU THE PRIMARY LOW CLOUD TYPE. THE LEADING EDGE OF THE BULK OF LOW CLOUDS TO THE NORTHEAST IS ABOUT 65 MILES NORTHEAST OF WINDWARD KAUAI. THE ENTIRE SOUTHERN HALF OF OAHU...AND ADJACENT NEAR SHORE WATERS...IS UNDER BROKEN TO OVERCAST CU AND SC...WITH FEW TO SCATTERED LOW CLOUDS CURRENTLY OVER THE NORTHERN HALF OF OAHU. MOST ISLAND AREAS OF MAUI COUNTY ARE CLOUDY THIS AFTERNOON...INCLUDING THE SUMMIT OF HALEAKALA...EXCEPT LEEWARD MOLOKAI...WHERE SKIES ARE MOSTLY SUNNY. ALL OF THE LOWER SLOPES OF THE BIG ISLAND...UP TO ABOUT 10 THOUSAND FEET...ARE COVERED IN OVERCAST SC AND CU...IN SHARP CONTRAST TO THIS MORNING/S SUNNY SKIES. SOME SMALL BREAKS IN THE OVERCAST CLOUD COVER ARE SEEN OVER THE LOWER WINDWARD SLOPES OF THE BIG ISLAND... NEAR CAPE KUMUKAHI...HILO AND HAKALAU. THE MASS OF SHOWERY LOW CLOUDS TO THE NORTHEAST IS ABOUT 125 MILES ACROSS NORTH TO SOUTH...AND IS ABOUT 350 MILES WIDE WHEN MEASURED FROM WEST-NORTHWEST TO EAST-SOUTHEAST. WATER VAPOR IMAGERY SHOWS A CLOSED LOW ALOFT CENTERED ABOUT 100 MILES SOUTHEAST OF THE BIG ISLAND...WITH A NORTHEAST TO SOUTHWEST ORIENTED TROUGH EXTENDING FROM 26N149W TO 12N156W. THE LOW HAS BEEN NEARLY STATIONARY OVER THE PAST 6 HOURS. AN ANTICYCLONE ALOFT IS CENTERED ABOUT 375 MILES WEST OF KAUAI...WITH THE END RESULT BEING A NORTH TO NORTHEAST FLOW ALOFT OVER THE ISLANDS. FAR SOUTH OF THE ISLANDS...ISOLATED THUNDERSTORMS REMAIN DISORGANIZED WITHIN THE NEAR EQUATORIAL TRADE WIND CONVERGENCE ZONE. $$ BIRCHARD +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
