THIN AND WISPY CIRRUS IS FURTHER EAST OVER THE REST OF THE ISLAND CHAIN. THESE HIGH CLOUDS ARE DRIFTING EAST...BUT ARE ALSO THINNING AND DISSIPATING AS THEY DO. LOCAL RADAR IMAGERY AND SURFACE OBSERVATIONS REVEALS THAT SCATTERED SHOWERS AND BROKEN LOW CLOUDS ARE LOCATED OVER THE WESTERN COAST OF KAUAI...AND A SHIELD OF INCREASINGLY INTENSE RAIN EXTENDS FROM WESTERN KAUAI OUT OVER 40 MILES TO THE WEST. ELSEWHERE...BROKEN LOW CLOUDS ARE FOUND OVER THE INTERIOR OF ALL OTHER ISLANDS...WITH CLOUD TOPS BETWEEN 9000 AND 11000 FEET. MOVEMENT OF THE LOW CLOUD FEATURES OVER THE STATE IS TOWARDS THE NORTHWEST AT 10 MPH OR LESS. ON THE LARGE SCALE ACROSS THE CENTRAL PACIFIC...A BROAD UPPER LEVEL TROUGH IS LOCATED ALONG THE NORTHERN BORDER OF THE AREA BETWEEN 160W AND THE DATELINE WITH A STRONG NORTHWESTERLY UPPER LEVEL JET NOSING INTO THE AREA NORTH OF 24N WEST OF 169W TO THE WEST OF A FAST MOVING UPPER LEVEL SHORTWAVE TROUGH. A NORTH TO SOUTH ORIENTED UPPER RIDGE AXIS IS LOCATED ACROSS THE MAIN HAWAIIAN ISLANDS...WITH AN UPPER LOW CENTERED AROUND 850 MILES NORTHEAST OF THE BIG ISLAND. THE WATER VAPOR IMAGERY LOOP SHOW THE UPPER LEVEL FEATURES ARE MOVING LITTLE EAST OF 160W...AS A BLOCKING PATTERN EXISTS IN THE EASTERN PACIFIC. A 250 MILE WIDE BAND OF LAYERED CLOUDS IS CENTERED ALONG A LINE FROM 18N162W TO 25N160W TO 30N158W...CROSSING WITHIN 120 MILES WEST OF KAUAI. SCATTERED THUNDERSTORMS WITH TOPS TO 48000 FEET ARE EMBEDDED WITHIN THIS CLOUD BAND. THIS CLOUD BAND IS PROGRESSING EAST AT A SLOW PACE...AT ABOUT 20 MPH AT 30N...BUT IS NEARLY STATIONARY AT 18N. ANOTHER 50 TO 100 MILE WIDE CLOUD BAND CONSISTING OF CUMULUS AND TOWERING CUMULUS IS POSITIONED ALONG A COLD FRONT FROM 30N160W TO 23N166W...MOVING EAST AT 10 TO 15 MPH. ANOTHER FRONTAL CLOUD BAND CONSISTING OF TOWERING CUMULUS WITH TOPS TO 20000 FEET AND LAYERED LOW CLOUDS ABOUT 70 MILES WIDE STRETCHES FROM 30N178W TO 27N180...OR ABOUT 40 MILES WEST OF MIDWAY ATOLL. AN AREA OF LAYERED MID TO HIGH CLOUDS WITH ISOLATED EMBEDDED THUNDERSTORMS IS LOCATED ALONG THE INTERTROPICAL CONVERGENCE ZONE FROM 10N158W TO 12N148W...THEN NORTHEASTWARD TO NEAR 16N140W. A FEW THIN CIRRUS IS FOUND NEAR THE UPPER TROUGH 800 MILES NORTHEAST OF THE BIG ISLAND. $$ BRENCHLEY +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
