THE BOUNDARY NEAR 30N LATITUDE WAS NEARLY STATIONARY WHILE THE SOUTH END JUST NORTH OF THE STATE WAS DRIFTING SLOWLY EAST NEAR 5 MILES AN HOUR. A FEW ISOLATED THUNDERSTORMS WERE FORMING ALONG AND WITHIN 150 MILES OF THE FRONTAL BOUNDARY. THE STORMS HAVE BEEN SLOWLY DIMINISHING NEAR THE ISLANDS THROUGHOUT THE DAY. THESE RELATIVELY WEAK STORMS TOPS HAD TOPS NEAR 30000 FEET THIS AFTERNOON. MOST OF THE CLOUDINESS ALONG THE FRONTAL BAND AS SEEN ON SATELLITE IMAGERY WAS DUE TO BROKEN TO OVERCAST CIRRUS CLOUDS. WATER VAPOR IMAGERY SHOWED A NARROW UPPER LEVEL TROUGH OVER OR JUST WEST OF OAHU. THE TROUGH WAS MIGRATING EAST AT 25 MILES AN HOUR. THE TROUGH AXIS STRETCHED FROM 30N 156.5W TO 20N 159.5W. THE CIRRUS ALONG THE FRONTAL CLOUD BAND WAS SITUATED IMMEDIATELY EAST OF THE TROUGH AXIS. AT 2 PM...THE VAST MAJORITY OF THE BIG ISLAND HAD CLOUDY SKIES DUE TO LOW CLOUDS FORMING FROM DAYTIME HEATING. SOUTHEAST MAUI HAD SOME LOW CLOUDINESS AS WELL. BUT THE REST OF THE STATE WAS MOSTLY SUNNY EXCEPT FOR SOME HIGH CLOUDS OVER LANAI AND MOLOKAI. PATCHES OF MOSTLY SCATTERED LOW CLOUDS WERE COMMON OVER THE SURROUNDING NEARBY WATERS. HOWEVER...THERE WERE A FEW TOWERING CUMULUS CLOUDS NEAR MAUI COUNTY...MAINLY SOUTH OF LANAI AND MAUI. $$ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
