STRONG HIGH PRESSURE AT THE SURFACE AND ALOFT CENTERED FAR NORTHEAST OF THE AREA GIVES WAY TO A DEEP UPPER LEVEL TROUGH NEAR THE DATE LINE EXTENDING SOUTH TO 25N. THE UPPER TROUGH IS SUPPORTING A SURFACE COLD FRONT 700 MILES NORTHWEST OF KAUAI THAT IS ADVANCING TO THE EAST NEAR 15 MPH. THE FRONT IS MARKED BY A 250 MILE-WIDE BAND OF OVERCAST LAYERED CLOUDS CENTERED ALONG 30N169W...25N174W...AND 23N180. ISOLATED THUNDERSTORMS EMBEDDED WITHIN THE FRONT NORTH OF 25N RISE TO 44 KFT. THE FRONT HAS DISPLACED THE SUBTROPICAL RIDGE SOUTHWARD TO ABOUT 350 MILES NORTHEAST OF KAUAI. EASTERLY TRADE WINDS ARE NOTED IN LOW CLOUD MOTIONS OF 20 TO 25 MPH...THOUGH CLOUD MOTIONS VEER OUT OF THE EAST SOUTHEAST JUST NORTH OF THE STATE. LOW CLOUD COVERAGE FOLLOWS A TYPICAL WINDWARD AND MAUKA PATTERN OVER MUCH OF THE MAIN HAWAIIAN ISLANDS THIS MORNING. PATCHES OF BROKEN LOW CLOUDS ARE CONFINED TO WINDWARD SLOPES OF MAUI... MOLOKAI...AND OAHU...WHILE A SMALL BAND OF BROKEN LOW CLOUDS IS PRODUCING A GREATER AMOUNT OF LOW CLOUDS OVER THE EASTERN HALF OF KAUAI AND ITS ADJACENT WATERS. FEW TO SCATTERED LOW CLOUDS ARE MOVING ACROSS WINDWARD WATERS AHEAD OF A 150 MILE BAND OF BROKEN CUMULUS CLOUDS SITTING 100 MILES OFF THE WINDWARD COASTS. A BAND OF HIGH CLOUDS IS OBSCURING MUCH OF THE BIG ISLAND THIS MORNING. THE 300 MILE-WIDE HIGH CLOUD BAND IS BEING GENERATED BY A SHARP UPPER LEVEL TROUGH CENTERED FROM 10N177W TO 10N160W THEN RUNNING OVER MAUI AND ENDING AT A WEAK UPPER LOW NEAR 26N150W. THE UPPER TROUGH IS MOVING TO THE SOUTHEAST SLOWLY AND IS TRIGGERING ISOLATED THUNDERSTORMS WITH TOPS TO 42 KFT ABOUT 75 MILES SOUTH OF THE BIG ISLAND FROM 18N TO 16N BETWEEN 158W AND 153W. ISOLATED THUNDERSTORMS ALSO RISE AS HIGH AS 47 KFT SOUTH OF 14N BETWEEN 174W AND 161W. FAR SOUTHEAST OF THE STATE...A PORTION OF THE ITCZ EAST OF 147W HAS LIFTED NORTH OF 10N...REACHING 13N. $$ DWROE +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
