A LOW LEVEL CONVERGENCE ZONE WAS LYING IMMEDIATELY SOUTHEAST OF THE FRONTAL BAND AND EXTENDED FROM 30N 140W TO 24N 150W. BROKEN TO OVERCAST LOW TO MID LEVEL CLOUDS ALONG THESE TWO FEATURES WERE COMMON WITHIN THE AREA BOUNDED BY POINTS 23N 150W...27N 150W... 30N 143W AND 30N 138W. REMNANT CLOUDS FROM THE TAIL END OF THE OLD FRONT CONTINUED AS SCATTERED TO BROKEN LOW CLOUDS FROM 26N 152W TO 23 160W. A MORE SUBSTANTIAL AMOUNT OF MOSTLY BROKEN LOW CLOUDS ASSOCIATED WITH THE CONVERGENCE ZONE EAST OF THE STATE WAS SPREADING OUT TOWARD THE ISLANDS. THESE LOW CLOUDS WERE COMMON WITHIN A TRIANGULAR REGION BOUNDED BY THE BIG ISLAND...24N 150W AND 15N 154W. SOME CLOUDS FROM THIS AREA IMMEDIATELY EAST OF THE BIG ISLAND WERE SLIDING TOWARD THE NORTHWEST AND JUST SKIRTING THE WINDWARD OR EAST SIDES OF THE ISLAND CHAIN. ALSO...A HANDFUL OF SMALL...SHORT-LIVED TYPE OF TOWERING CUMULUS AND/OR THUNDERSTORMS WERE NOTED WITHIN THIS CLOUD AREA FROM 21N 151W TO 19N 152.5W. TOPS OF THESE UNSTABLE CLOUD FEATURES WERE BETWEEN 25000 AND 27000 FEET. ELSEWHERE... CLOUD TOPS NEAR THE ISLANDS WERE GENERALLY IN THE 10000 TO 13000 FEET RANGE. A WEAK UPPER LOW IN THE VICINITY OF 16N 150W WAS MOVING SLOWLY EAST. THIS UPPER LOW WAS GENERATING A SWATH OF LAYERED CLOUDS INCLUDING CIRRUS GENERALLY BETWEEN 15N AND 20N FROM 140W TO 150W. ANOTHER LARGE FRONTAL SYSTEM NORTHWEST OF THE STATE WAS INCHING ITS WAY TOWARD US. THE FRONT CURRENTLY EXTENDED THROUGH 30N 172W AND 23N 180E. THE ASSOCIATED CLOUD BAND WAS ABOUT 300 MILES WIDE. BROKEN LOW CLOUDS AHEAD OF THE FRONT IN THE AREA BETWEEN 162W AND 170W...NORTH OF 23N...WERE FLOWING NORTHWARD IN TOWARDS THE APPROACHING FRONT. $$ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
