THE TROUGH EXTENDS NORTH TO SOUTH ALONG 175W. WINDS ALOFT EAST OF THE TROUGH ARE DIVERGENT... COMING OUT OF THE SOUTH-SOUTHWEST OVER KAUAI AND OAHU...AND OUT OF THE WEST-SOUTHWEST OVER THE REST OF THE STATE. SUCH DIFFLUENT FLOW AT UPPER LEVELS OF THE ATMOSPHERE AID AND ABET THE FORMATION OF WIDESPREAD SHOWERS AND THUNDERSTORMS. NUMEROUS THUNDERSTORMS WERE LOCATED IN A TRIANGULAR SHAPED AREA BOUNDED BY 25N160W TO 11N155W TO 15N165W TO 25N160W. ADDITIONAL THUNDERSTORMS WERE LOCATED SOUTHWEST OF THE ISLANDS IN AN AREA FROM 15N TO 23N BETWEEN 166W AND 171W. OVERCAST HIGH CLOUDS BLOWN OFF THE TOPS OF THE THUNDERSTORMS OBSCURE THE CLOUDS BELOW...BUT NEXRAD INDICATES THAT THERE ARE MERGING CLOUD LAYERS ALL THE WAY UP TO 35 THOUSAND FEET. THIS IS IN GOOD AGREEMENT WITH SATELLITE-DERIVED CLOUD TOPS. ALSO EAST OF THE TROUGH ALOFT IS A SOUTHWEST TO NORTHEAST JETSTREAM RUNNING THROUGH 30N170W...OR ABOUT 800 MILES NORTHWEST OF KAUAI. THE JETSTREAM IS CARRYING HIGH CLOUDS FROM THE THUNDERSTORMS ALL THE WAY TO NORTHERN CALIFORNIA...WASHINGTON...AND OREGON. THE AREA AS A WHOLE...CONSISTING OF MULTILAYERED CLOUDS AND EMBEDDED THUNDERSTORMS...LAYS FROM 10N TO 30N BETWEEN 150W AND 175W. THE AREA IS NEARLY STATIONARY. $$ CRAIG +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
