THE LOW CLOUDS FROM THE DECAYED FRONTAL BAND NOW BLENDED IN WITH ALL THE OTHER LOW CLOUDS SURROUNDING THE HAWAIIAN ISLANDS. RANDOMLY DISTRIBUTED PATCHES AND SMALL CLUSTERS OF SCATTERED TO BROKEN LOW CLOUDS SURROUNDED THE STATE. EACH OF THESE LOW CLOUDS WERE SEPARATED BY FAIRLY GENEROUS AMOUNTS OF CLEAR SKY. THE LOW CLOUDS NEAR THE ISLANDS WERE MOVING WEST NEAR 25 MILES AN HOUR. WATER VAPOR IMAGERY SHOWED AN UPPER LEVEL TROUGH EXTENDING THROUGH 30N 132W TO 26N 140W TO 23N 155W. THE WEST END OF THE TROUGH WAS MOVING SOUTHEAST NEAR 35 MILES AN HOUR WHILE THE EAST SEGMENT WAS MOVING DUE EAST. A 275 MILES WIDE STRAND OF BROKEN TO OVERCAST CIRRUS SAT IMMEDIATELY SOUTH OF THE TROUGH. THE CIRRUS WAS CENTERED ALONG A LINE FROM 20N 151W TO 23N 135W. THIS LARGE STRAND OF HIGH CLOUDS WAS MOVING EAST AT 50 TO 60 MILES AN HOUR. A DISTINCT UPPER LEVEL LOW WAS NEAR 25N 172E. TWO OTHER WEAKER... NEARLY INDISCERNIBLE UPPER LOWS WERE NEAR 21N 177W AND 30N 180E. THE UNSTABLE AIR MASS IN THIS REGION WAS GENERATING WIDELY SCATTERED THUNDERSTORMS FROM 17N TO 31N BETWEEN 172W AND 178E. THE THUNDERSTORMS SOUTH OF 23N WERE NEARLY STATIONARY. THOSE NORTH OF 23N WERE DRIFTING NORTHWARD. TWO NORTHWEST TO SOUTHEAST ALIGNED BANDS OF BROKEN TO OVERCAST LAYERED CLOUDS...EACH CONTAINING A HANDFUL OF SMALL...ISOLATED THUNDERSTORMS...WERE LOCATED FROM 15N TO 30N BETWEEN 162W AND 170W. ELSEWHERE...ISOLATED TO WIDELY SCATTERED THUNDERSTORMS ALONG THE ITCZ WERE MAINLY FORMING BETWEEN 06N AND 10N FROM 135W TO 170W. MOST OF THE STORMS HAD WEAKENED DURING THE NIGHT. BUT SOME OF THE HIGHEST STORM TOPS WERE STILL UP NEAR 47000 FEET. $$ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
