NEAR THE ISLANDS...INDIVIDUAL LOW CLOUDS ARE TRAVELLING FROM THE EAST NORTHEAST AT 15 TO 19 MPH...ESSENTIALLY UNCHANGED FROM THIS MORNING BUT A SLIGHT DECREASE IN SPEED SINCE YESTERDAY AFTERNOON. LOW CLOUD COVERAGE OVER THE ISLANDS IS FOLLOWING A RATHER TYPICAL TRADE-WIND PATTERN THIS AFTERNOON. CLOUD COVERAGE IS SLIGHTLY GREATER OVER WATERS JUST EAST OF THE BIG ISLAND AND MAUI COMPARED TO THE REST OF THE STATE...THOUGH WINDWARD PORTIONS OF ALL ISLANDS ARE COVERED WITH BROKEN LOW CLOUDS. AFTERNOON SEA BREEZES HAVE LED TO THE DEVELOPMENT OF BROKEN TO OVERCAST LOW CLOUDS OVER ALL LEEWARD SLOPES OF THE BIG ISLAND AS WELL AS WINDWARD KAU. SEA BREEZES ON THE SMALLER ISLANDS HAVE PRODUCED PATCHES OF BROKEN LOW CLOUDS ALONG LEEWARD TERRAIN. STABLE CONDITIONS PREVAIL OVER THE MAIN HAWAIIAN ISLANDS. HOWEVER... DEEPENING UPPER LEVEL TROUGHING SEVERAL HUNDRED MILES NORTH OF THE STATE IS LEADING TO A SLOW DECREASE IN THE DEGREE OF SUBSIDENCE OVER THE ISLANDS INFERRED FROM WATER VAPOR IMAGERY. THE UPPER TROUGH RUNS ALONG THREE UPPER LOWS CENTERED NEAR 24N178W...30N166W...AND NORTH OF THE AREA NEAR 33N149W. NARROW STREAKS OF BROKEN HIGH CLOUDS ARE FOUND ALONG THE FLANKS OF THE UPPER LOW NEAR 30N...WHILE THE UPPER LOW NEAR 24N IS GENERATING A SMALL SHIELD OF BROKEN HIGH CLOUDS 500 MILES WEST OF KAUAI. TO THE SOUTHEAST OF THE STATE...A NEARLY STATIONARY SURFACE TROUGH IS EMBEDDED WITHIN THE ITCZ ALONG 13N140W AND 10N149W. ISOLATED THUNDERSTORMS RISE AS HIGH AS 49 KFT WITHIN 100 MILES OF THE TROUGH. $$ DWROE +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
