THE FIRST AREA IS BROKEN IN COVERAGE WITH ITS LEADING EDGE IN THE KAUAI CHANNEL. IN ITS WAKE...THE AREA HAS BROUGHT BROKEN CONDITIONS TO PRIMARILY THE WINDWARD SECTION OF OAHU. THE SECOND AREA IS MORE OVERCAST IN COVERAGE WITH ITS LEADING EDGE NOW REACHING THE WINDWARD SIDE OF THE BIG ISLAND. THE LOW CLOUDS...MADE UP OF OF MAINLY STABLE STRATOCUMULUS /SC/ IS THE REASON WHY FOR THE LACK OF SHOWERS ON WEATHER RADAR. WEATHER RADAR IS ONLY DETECTING SPOTTY LIGHT SHOWERS. THE LOW CLOUDS ARE MOVING WEST...WITH THE TRADE WINDS...OF 15 TO 20 MPH. THE INITIAL AREA OF LOW CLOUDS HAS ALSO LEFT BEHIND SOME LOCAL BROKEN COVERAGE IN THE LEEWARD WATERS OF OAHU...MOLOKAI AND THE KONA WATERS. SKIES ARE MOSTLY CLEAR OVER THE THE REMAINING AREAS OF THE BIG ISLAND. THE SKIES AROUND KAUAI COUNTY IS MOSTLY CLEAR NOW THAT AN AREA OF HIGH LEVEL CIRRUS CLOUDS HAS PASSED NORTH OF THE ISLAND. AS NOTED ABOVE HOWEVER...SOME LOW CLOUDS ARE ADVANCING TOWARD KAUAI. AN UPPER LEVEL TROUGH WITH A COUPLE OF POSSIBLE LOWS...APPEARS TO HAVE EASED SLIGHTLY SOUTH AND EAST DURING THE COURSE OF THE EVENING. ONE APPARENT LOW IS 700 MILES NORTHWEST OF KAUAI NEAR 31N166W. A TROUGH EXTENDS SOUTHWESTWARD FROM THIS LOW TO 27N177W. ANOTHER TROUGH EXTENDS NORTHEASTWARD TO ANOTHER LOW AT 35N157W. THE AREA TO THE SOUTH AND EAST OF THE UPPER LEVEL TROUGH AND LOWS...INCLUDING THE HAWAIIAN ISLANDS...IS A SUB TROPICAL JET STREAM WITH A SOUTHWESTERLY WIND FLOW. IT IS TRANSPORTING HIGH LEVEL MOISTURE IN THE FORM OF CIRRUS CLOUDS FROM DEBRIS OF THUNDERSTORMS BETWEEN WAKE ISLAND AND KWAJALEIN ATOLL...LOCATED 1700 MILES WEST SOUTHWEST OF KAUAI. SATELLITE ANIMATION SHOWS MORE CIRRUS...OF THE THINNER VARIETY...APPROACHING KAUAI FROM THE SOUTH. DEEP CONVECTION ASSOCIATED WITH THE DISTURBED AREA SOME 750 MILES SOUTH SOUTHWEST OF THE BIG ISLAND HAS JUST ABOUT TOTALLY COLLAPSED. ISOLATED BUT STRONG CONVECTION ARE OCCURRING BETWEEN 800 AND 1300 MILES SOUTHWEST OF KAUAI BETWEEN 13N AND 08N FROM 168W TO 171W. $$ LAU +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
