THIS AREA SHOWS UP IN THE POLAR ORBITER PRECIPITABLE WATER DATA AS A NORTHWEST TO SOUTHEAST WEDGE OF HIGHER MOISTURE WITH VALUES FROM 1.3 INCHES NEAR MOLOKAI TO 1.5 INCHES NEAR THE BIG ISLAND. PRECIPITABLE WATER VALUES WERE LESS THAN AN INCH TO THE NORTHEAST AND SOUTHWEST OF THE WEDGE. THE LEADING EDGE OF THE SHOWERY LOW CLOUDS WAS ABOUT 120 MILES SOUTHWEST OF LAHAINA AND ITS TRAILING EDGE WAS 40 TO 50 MILES NORTHEAST OF KAHULUI. BROKEN TO OVERCAST CONDITIONS HAVE COVERED THE WINDWARD SLOPES FROM OAHU TO THE BIG ISLAND. RADAR DATA INDICATED SCATTERED LIGHT TO MODERATE SHOWERS FALLING FROM THESE CLOUDS. NORTHEAST OF THE SHOWER AREA WAS A 100 MILE WIDE BAND OF MOSTLY CLEAR SKIES FOLLOWED BY ANOTHER AREA OF BROKEN TO OVERCAST LOW CLOUDS. IN ADDITION TO THE WINDWARD CLOUDINESS...LEEWARD SLOPES OF THE BIG ISLAND AND MAUI HAVE BECOME COVERED BY BROKEN TO OVERCAST CLOUDS. THESE CLOUDS HAVE PUSHED UP THE SLOPES OF MAUNA KEA AND MAUNA LOA SOMEWHAT HIGHER THAN NORMAL AS CLOUD EDGES REACH UP TO ABOUT 10000 FT. KAUAI WAS THE OUTLIER WITH ONLY SCATTERED LOW CLOUDS AND A PATCH OF BROKEN THIN HIGH CLOUDS OVERHEAD. WATER VAPOR IMAGES SHOWED A WEAK AND POORLY DEFINED UPPER LEVEL LOW CENTERED NEAR 20N 147W. A BROAD TROUGH EXTENDS FROM THE LOW TO ABOUT 10N 152W. ALTHOUGH LIMITED IN DEEP CONVECTION...THE TROUGH HAD QUITE A BIT OF HIGH CLOUDS WITH BROKEN TO OVERCAST CIRRUS COVERAGE EXTENDING SOUTHEAST OF A LINE FROM 20N 139W TO 11N 150W. THE INTERTROPICAL CONVERGENCE ZONE...ITCZ...STRADDLES 10N WITH MOST OF THE ASSOCIATED DEEP CONVECTION WEST OF 162W. THERE WAS VERY LIMITED AMOUNTS OF DEEP CONVECTION WITHIN THE ITCZ BETWEEN 140W AND 162W. THE DEEP CONVECTION WEST OF 170W HAD TOPS PUSHING ABOVE 53000 FT. $$ KODAMA +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
