HIGH PRESSURE GIVES WAY TO A SHARP UPPER LEVEL TROUGH ALONG 22N140W TO 21N147W THAT IS DIGGING TO THE SOUTHEAST AT 25 MPH. THIS UPPER TROUGH IS DRIVING A WEAK SURFACE FRONT OR SHEAR LINE THAT IS MARKED BY A 125 MILE-WIDE BAND OF BROKEN CUMULUS AND STRATOCUMULUS CLOUDS CENTERED ALONG 25N140W...23N153W... AND 26N165W. THIS FEATURE IS MOVING TO THE SOUTH AROUND 10 MPH. THE ABOVE MENTIONED CLOUD BAND IS CURRENTLY LOCATED 20 MILES NORTH OF KAUAI...LEAVING A RATHER TYPICAL LOW CLOUD PATTERN OVER THE ISLANDS. BROKEN LOW CLOUDS ARE CONFINED TO WINDWARD SLOPES OF THE SMALLER ISLANDS...THOUGH NARROW CLOUD BANDS DOWNWIND OF AND PARALLEL TO THE KOOLAU RANGE ARE OBSERVED ACROSS CENTRAL OAHU. THESE CLOUD BANDS SUGGEST THE PRESENCE OF LOW LEVEL TURBULENCE. ON THE BIG ISLAND...BROKEN TO OVERCAST LOW CLOUDS COVER ALL LOWER SLOPES BELOW 6500 KFT WITH THE EXCEPTION OF THE NORTH KOHALA AND NORTH KONA DISTRICTS AND THE KAU DESERT. INDIVIDUAL LOW CLOUDS NEAR THE ISLANDS ARE TRAVELLING FROM THE EAST NORTHEAST AT 25 TO 30 MPH. A WEAK...ELONGATED UPPER LEVEL LOW LOCATED NEAR 21N166W IS TRIGGERING ISOLATED TOWERING CUMULUS CELLS WITH TOPS TO 30 KFT 250 TO 400 MILES SOUTHWEST OF KAUAI. THE UPPER LOW IS MOVING TO THE WEST NORTHWEST AT 10 MPH AND IS HAVING LITTLE EFFECT ON THE WEATHER NEAR THE ISLANDS. 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 12N BETWEEN 175W 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.
