AN AREA OF BROKEN TO OVERCAST HIGH CLOUDS SOUTH AND EAST OF A LINE FROM 11N170W TO 20N163W TO 24N158W TO 14N146W MARKS THE EASTERN FLANK OF THE TROUGH. THESE HIGH CLOUDS ARE AFFECTING THE MAIN HAWAIIAN ISLANDS THIS EVENING...BLOCKING THE VIEW OF LOW CLOUDS THERE. ISOLATED CUMULONIMBUS...CB...EMBEDDED WITHIN BROKEN LAYERED CLOUDS FORM A RAGGED 180 MILE WIDE BAND NORTH OF A LINE FROM 07N140W TO 08N160W TO 04N170W TO 04N180W. BETWEEN 170W AND 146W...THIS CLOUD BAND IS MERGED WITH THE AREA OF HIGH CLOUDS MENTIONED PREVIOUSLY. A RAGGED 180 TO 240 MILE WIDE BAND OF BROKEN LAYERED CLOUDS LIES NORTH OF A LINE FROM 25N163W TO 31N150W TO 33N145W. THIS FEATURE...MARKING A FRONTAL BOUNDARY...CONTINUES NORTHEASTWARD AS A BAND OF SCATTERED TO BROKEN HIGH CLOUDS NORTH OF A LINE FROM 33N145W TO 34N140W THEN BEYOND TOWARD THE MAINLAND. THIS BAND HAS NOT MOVED MUCH OVER THE PAST 12 HOURS. OVERCAST LAYERED CLOUDS NORTH AND WEST OF A LINE FROM 33N180W TO 30N172W TO 42N154W MARK ANOTHER FRONTAL BOUNDARY. MOVEMENT IS TOWARD THE EAST AT 40 MPH NEAR 40N. SATELLITE LOOP SHOWS A BROAD ANTICYCLONIC CIRCULATION AT LOW CLOUD LEVEL SOUTH OF THE FIRST FRONTAL BAND. THE MAIN HAWAIIAN ISLANDS LIE NEAR THE WESTERN EDGE OF THIS CIRCULATION...WITH EMBEDDED LOW CLOUDS SLIPPING BENEATH THE HIGH CLOUD COVER A HUNDRED MILES OR SO EAST OF MAUI AND THE BIG ISLAND. USING GAPS IN THE HIGH CLOUDS IN OLDER VISIBLE IMAGERY AS A GUIDE...IT SEEMS THAT LOW CLOUDS ARE RATHER SPARSE ACROSS LEEWARD PORTIONS OF KAUAI AND OAHU. THE WINDWARD THIRD OF OAHU HAD BROKEN LOW CLOUDS. BROKEN TO OVERCAST LOW CLOUDS ALSO COVERED WINDWARD HALEAKALA SLOPES ON MAUI AS WELL AS WINDWARD WEST SLOPES. HIGH CLOUDS ARE TOO THICK...AND HAVE BEEN TOO THICK SINCE LATE AFTERNOON...TO ASSESS LOW CLOUD COVERAGE. $$ POWELL +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
