THE TRADES ARE BEING GENERATED BY STRONG HIGH PRESSURE AT THE SURFACE AND ALOFT ABOUT 900 MILES NORTH OF THE STATE. A 125 MILE WIDE BAND OF BROKEN CUMULUS CLOUDS STRETCHES FOR 1300 MILES ALONG 19N164W AND 18N144W AND IS IMPACTING THE BIG ISLAND THIS MORNING. BROKEN TO OVERCAST LOW CLOUDS COVER ALL WINDWARD SLOPES INCLUDING THE KAU DISTRICT...AND CLOUD TOPS RISE BETWEEN 12 TO 15 KFT...HIGH ENOUGH TO REACH THE SUMMITS OF MAUNA KEA AND MAUNA LOA AT TIMES. IN ADDITION...AN AREA OF BROKEN LOW CLOUDS IS SITTING ON THE LOWER SLOPES OF THE SOUTH KONA DISTRICT. ABOUT 400 MILES WEST OF THE BIG ISLAND...ISOLATED THUNDERSTORMS WITH TOPS TO 37 KFT ARE EMBEDDED WITHIN THE BAND. THE TRIGGER FOR THE THUNDERSTORMS IS AN ELONGATED UPPER LEVEL LOW NEAR 20N165W THAT IS DRIFTING WESTWARD. ANOTHER...NARROW...50 MILE WIDE CLOUD BAND IS IMPACTING KAUAI AND IS SKIRTING JUST NORTH OF OAHU. THE CLOUD BAND EXTENDS 325 MILES EAST OF KAUAI...RESULTING IN BROKEN TO OVERCAST LOW CLOUDS OVER THE EASTERN HALF OF THE GARDEN ISLE. A LESSER AMOUNT OF CLOUD COVER IS OBSERVED ACROSS MAUI COUNTY AND MOST OF OAHU...WHERE PATCHES OF BROKEN LOW CLOUDS ARE LIMITED TO WINDWARD SLOPES. INDIVIDUAL LOW CLOUDS NEAR THE ISLANDS ARE TRAVELLING FROM THE EAST NORTHEAST AT 30 MPH. ANOTHER...EXTENSIVE CLOUD BAND 115 MILES NORTH OF KAUAI MARKS A SHEAR LINE. THE 125 MILE WIDE BAND OF BROKEN CUMULUS AND STRATOCUMULUS CLOUDS OF THE COLD FRONT RUNS ALONG 26N140W TO 24N146W AND IS MOVING TO THE SOUTHEAST AT 10 MPH. THE CLOUD BAND CONTINUES TO THE WEST AS SHEAR LINE ALONG 24N146W TO 24N150W TO 26N163W THAT IS MOVING SOUTHWARD AT 10 MPH. THE FRONT IS BEING DRIVEN BY A SHARP UPPER LEVEL TROUGH ALONG 24N140W TO 22N148W THAT IS DIVING TO THE SOUTHEAST AT 25 MPH. TO THE SOUTH OF THE STATE...ISOLATED THUNDERSTORMS WITHIN THE ITCZ ARE CONFINED MAINLY SOUTH OF 10N...THOUGH SOME THUNDERSTORMS ARE NOTED BETWEEN 10N AND 11N BETWEEN 165W AND 155W. $$ DWROE +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
