STRONG HIGH PRESSURE AT THE SURFACE AND ALOFT CENTERED FAR NORTHEAST OF THE AREA GIVES WAY TO A DEEP UPPER LEVEL TROUGH ALONG 175W EXTENDING SOUTH TO 25N. THE UPPER TROUGH IS SUPPORTING A SURFACE COLD FRONT 625 MILES NORTHWEST OF KAUAI. THE FRONT IS MARKED BY A 250 TO 300 MILE-WIDE BAND OF OVERCAST LAYERED CLOUDS CENTERED ALONG 30N168W...24N175W... AND 23N180. THIS FEATURE IS MOVING TO THE EAST AROUND 15 MPH EAST OF 175W...BECOMING NEARLY STATIONARY TO THE WEST. ISOLATED... EMBEDDED THUNDERSTORMS RISE TO ABOUT 45 KFT WITHIN THE FRONT EAST OF 175W. THE FRONT HAS DISPLACED THE SUBTROPICAL RIDGE SOUTHWARD TO ABOUT 350 MILES NORTHEAST OF KAUAI. AS A RESULT...SCATTERED LOW CLOUDS OFF THE WINDWARD COASTS OF THE MAIN HAWAIIAN ISLANDS ARE TRAVELLING FROM THE EAST SOUTHEAST AT 20 TO 25 MPH...WHILE LOW CLOUDS JUST SOUTH OF THE ISLANDS ARE MOVING FROM THE EAST AROUND 15 MPH. A BAND OF BROKEN CUMULUS CLOUDS 60 MILES NORTHEAST OF THE ISLANDS IS CAUGHT UP IN THE EAST SOUTHEASTERLY FLOW...CAUSING IT TO ADVANCE SLOWLY TOWARD THE STATE. WITH THE CLOUD BAND REMAINING EAST OF THE STATE...LOW CLOUDS ON THE ISLANDS FOLLOW A TYPICAL WINDWARD AND MAUKA PATTERN IN MOST LOCALES. PATCHES OF BROKEN LOW CLOUDS ARE CONFINED TO WINDWARD TERRAIN ON THE SMALLER ISLANDS. HOWEVER...A NARROW PLUME OF LOW CLOUDS ORIGINATING FROM WEST MOLOKAI IS EXTENDED TOWARD SOUTHEAST OAHU. ON WINDWARD BIG ISLAND...PATCHES OF BROKEN LOW CLOUDS ARE FOUND ON THE KAU SLOPES AND THE WAIPIO VALLEY VICINITY. BROKEN LOW CLOUDS HAVE ALSO DEVELOPED ALONG THE HEATED...LEEWARD SLOPES NORTH OF KEAHOLE POINT. A SHARP...BUT WEAK...UPPER LEVEL TROUGH EXTENDS FROM 10N174W TO 18N160W THEN RUNS OVER MAUI TO A WEAK UPPER LOW NEAR 27N150W. THE UPPER LOW IS MOVING EAST SLOWLY...WHILE THE UPPER LOW IS DRIFTING WESTWARD. A BAND OF SCATTERED TO BROKEN HIGH CLOUDS EXTENDS 400 MILES TO THE SOUTH AND EAST OF THE UPPER TROUGH...AND INSTABILITY ASSOCIATED WITH THIS FEATURE IS TRIGGERING ISOLATED THUNDERSTORMS WITH TOPS TO 42 KFT ABOUT 75 MILES SOUTH OF THE BIG ISLAND FROM 18N TO 16N BETWEEN 158W AND 154W. FAR SOUTHEAST OF THE STATE...A PORTION OF THE ITCZ EAST OF 148W HAS LIFTED NORTH OF 10N...REACHING 14N. $$ DWROE +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
