ALTHOUGH A PLETHORA OF LOW CLOUDS ARE MOVING TOWARD THE ISLANDS IN A MODERATE TRADE FLOW THIS MORNING...LOW CLOUDS ARE NEARLY NON-EXISTENT JUST NORTH OF THE ISLANDS...FROM 25N TO 30N BETWEEN 160W AND 140W. THIS NEARLY CLEAR AREA OUTLINES THE AXIS OF A SURFACE RIDGE...WHICH IS EAST-WEST ORIENTED ALONG 28N...BASED ON LOW CLOUDS MOVING TOWARD THE WEST SOUTH OF THIS LATITUDE...AND LOW CLOUDS HEADING EAST NORTH OF THIS LATITUDE. KAUAI IS A BIT OF AN OUTLIER THIS MORNING...AS MOSTLY SUNNY SKIES PREVAIL ISLAND-WIDE...AND OVER ADJACENT WATERS...WITH JUST FEW TO SCATTERED SMALL CU OVER INTERIOR PORTIONS OF THE ISLAND. HEADING EAST FROM KAUAI LOW CLOUDS INCREASE IN COVERAGE...AND BECOME BROKEN TO OVERCAST FROM OAHU EASTWARD. OAHU IS CURRENTLY MOSTLY CLOUDY... WITH BROKEN SC AND CU OVER THE ISLAND AND NEAR SHORE WATERS. WINDWARD AREAS OF MAUI...MOLOKAI AND THE BIG ISLAND ARE ALSO MOSTLY CLOUDY WITH BROKEN TO OVERCAST SC AND CU OVER THE LOWER SLOPES AND ADJACENT WATERS. LEEWARD AREAS OF THESE ISLANDS ARE MOSTLY SUNNY... BUT BROKEN LOW CLOUDS ARE OVER MAUI LEEWARD WATERS BETWEEN LANAI AND KAHOOLAWE. LOW CLOUD MOTION NEAR THE ISLANDS IS TOWARD THE WEST AT SPEEDS NEAR 23 MPH. HIGH CLOUDS THAT WERE OVER KAUAI AND OAHU AT THIS TIME YESTERDAY HAVE MOVED WEST OF THE ISLANDS...AS THE SUPPORTING UPPER LOW... CENTERED FAR WEST OF THE ISLANDS...HAS MOVED WEST OVER THE PAST 12 HOURS. THE LOW IS NOW CENTERED NEAR 22N 176W...AND HAS A TROUGH AXIS THROUGH 30N 169W TO THE LOW CENTER ABOUT 1000 MILES WEST OF KAUAI... TO 13N 180. THUNDERSTORMS CONTINUE TO DEVELOP NEAR THE CORE OF THE LOW...AND ARE CURRENTLY LOCATED FROM 19N TO 25N BETWEEN 174W AND THE DATE LINE. ISOLATED THUNDERSTORMS HAVE DEVELOPED IN ASSOCIATION WITH A WEAK TROPICAL LOW PASSING WELL SOUTH OF THE ISLANDS...NEAR 11N 153W. THE WESTWARD MOVING DISTURBANCE LACKS SIGNIFICANT ORGANIZATION...AND MARKS THE ONLY DEEP CONVECTION IN THE DEEP TROPICS OF THE CENTRAL NORTH PACIFIC. $$ BIRCHARD +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
