THOUGH A COMPLEX PATTERN IS IN PLACE ALOFT. A DEEP...THOUGH NOT PARTICULARLY STRONG...UPPER LEVEL TROUGH OCCUPIES MUCH OF THE CENTRAL PACIFIC...BOTTOMING OUT NEAR 10N155W. A 400 MILE-WIDE SHIELD OF BROKEN HIGH CLOUDS CENTERED ALONG 10N153W...16N145W...AND 24N142W RUNS ALONG THE EASTERN FLANK OF THE UPPER TROUGH. A WEAK...EMBEDDED UPPER LOW 225 MILES EAST OF THE BIG ISLAND NEAR 20N152W IS TRIGGERING A SMALL CLUSTER OF ISOLATED THUNDERSTORMS WITH TOPS TO 46 KFT ABOUT 250 TO 350 MILES SOUTHEAST OF THE BIG ISLAND. A SHORT WAVE DROPPING INTO THE THE UPPER LEVEL TROUGH IS ALSO DRIVING A SURFACE FRONT ABOUT 550 MILES NORTH OF KAUAI. THE FRONT IS DRIFTING SOUTH SLOWLY AND IS MARKED BY BROKEN LAYERED CLOUDS WITH ISOLATED...EMBEDDED THUNDERSTORMS WITH TOPS TO 41 KFT ALONG 30N BETWEEN 170W AND 155W. THE MAIN HAWAIIAN ISLANDS LIE IN A REGION OF SUBSIDENCE WEST OF THE UPPER TROUGH AXIS...WITH AN ERODING MID LEVEL RIDGE HANGING ON. AS A RESULT...STABLE CONDITIONS PREVAIL...WITH TWO AREAS OF LOW CLOUDS OBSERVED NEAR THE ISLANDS. A FIELD OF MOSTLY STABLE...BROKEN STRATOCUMULUS CLOUDS WITH TOPS AROUND 7500 FT LIES JUST OFF WINDWARD MAUI AND BIG ISLAND AND EXTENDS 600 MILES TO THE EAST. A POORLY ORGANIZED...250 MILE-WIDE BAND OF BROKEN CUMULUS AND STRATOCUMULUS CLOUDS WITH TOPS TO 9000 FT EXTENDS FOR 775 MILES FROM 25N156W TO 19N168W. A LESS THAN NORMAL AMOUNT LOW CLOUDS ARE CONFINED TO WINDWARD AREAS OF MOST ISLANDS...WITH A GREATER AMOUNT OF CLOUDS FOUND NEAR KAUAI DUE TO THE ABOVE-MENTIONED CLOUD BAND. BROKEN LOW CLOUDS COVER WINDWARD AND MAUKA PORTIONS OF THE GARDEN ISLE AND THE ADJACENT WATERS. BROKEN LOW CLOUDS ARE OBSERVED ALONG THE SPINE OF THE KOOLAU RANGE ON OAHU...WHILE SMALL PATCHES OF BROKEN LOW CLOUDS ARE LIMITED TO THE EASTERN TIPS OF MOLOKAI AND MAUI AND THE HILO VICINITY OF THE BIG ISLAND. EXCEPT FOR KAUAI...LEEWARD AREAS ARE CLOUD-FREE. THE FRONT TO THE NORTH OF THE ISLANDS IS WEAKENING THE TRADE WIND FLOW NEAR THE ISLANDS...WHERE INDIVIDUAL LOW CLOUDS ARE MOVING TO THE EAST NORTHEAST AT 13 TO 18 MPH. $$ DWROE +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
