SKIES REMAIN MOSTLY CLEAR OVER THE ISLANDS FROM NIIHAU TO MAUI. SKIES ARE CLEAR OVER THE BIG ISLAND OF HAWAII EXCEPT FOR BROKEN LOW CLOUDS OVER THE SLOPES FROM HILO TOWN TO KILAUEA. A NEARLY STATIONARY 20 MILE WIDE BAND OF OVERCAST LAYERED CLOUDS AND SCATTERED TOWERING CUMULUS CLOUDS...TCU...LIES JUST OFF THE NORTHEAST COAST OF THE BIG ISLAND. THERE ARE BROKEN LOW CLOUDS OVER WATER OVER THE EAST SIDE OF THE ALENUIHAHA CHANNEL AND JUST EAST OF MAUI. OTHERWISE...SKIES ARE NEARLY CLEAR OVER WATER CLOSE TO THE MAIN HAWAIIAN ISLANDS. THERE ARE NOT VERY MANY LOW CLOUDS AROUND THE MAIN HAWAIIAN ISLANDS WEST OF MAUI TO FOLLOW ON OUR SATELLITE LOOPS TO GET CLOUD MOTIONS...BUT AS BEST I CAN TELL THE CLOUDS AROUND THE ISLANDS FROM MOLOKAI TO NIIHAU ARE MOVING FROM THE EAST NORTHEAST AT AROUND 10 MPH. A 125 MILE WIDE FRONTAL CLOUD BAND LIES NORTH OF A LINE FROM 35N150W TO 370 MILES NORTH OF KAUAI TO 30N177W TO 29.5N180W. THE PART OF THE BAND NORTHEAST OF 28N154W CONTAINS DEEP OVERCAST LAYERED CLOUDS AND SCATTERED CUMULONIMBUS CLOUDS...CB...WITH TOPS TO 46000 FT. THE PART OF THE BAND FROM 154W TO 159W CONTAINS BROKEN LAYERED CLOUDS AND ISOLATED CB WITH TOPS TO 30000 FT. THE PART OF THE BAND WEST OF 150W CONTAINS SHOWERY BROKEN TO OVERCAST LOW CLOUDS. OVER THE PAST 12 HOURS THE PART OF THE FRONTAL BAND EAST OF 165W HAS BEEN MOVING TOWARD THE SOUTHEAST AT 10 MPH WHILE THE PART WEST OF 165W HAS BEEN NEARLY STATIONARY. A 70 MILE WIDE PREFRONTAL CONVERGENCE BAND IS CENTERED FROM 25N170W TO 25N166W TO 26N163W TO 28N158W WHERE IT MERGES WITH THE FRONTAL BAND. THE PREFRONTAL BAND CONTAINS MAINLY BROKEN LOW CLOUDS WITH A COUPLE OF CB ALONG THE SOUTH EDGE OF THE BAND NEAR 162W. THE SHEAR LINE HAS BEEN MOVING SOUTHEAST AT 10 MPH. A 450 MILE WIDE AREA OF BROKEN TO OVERCAST LAYERED CLOUDS AND ISOLATED EMBEDDED CB IS SOUTHEAST OF A LINE FROM 27N147W TO 435 MILES EAST SOUTHEAST OF HILO TO 10N156W. OVER THE PAST SEVERAL HOURS THIS AREA HAS SHIFTED EAST SLOWLY AND THE CB HAVE WEAKENED. WATER VAPOR IMAGERY...WHICH SHOWS FEATURES MAINLY ABOVE 24000 FT... SHOWS A TROUGH ALOFT FROM 25N149W OVER THE ALENUIHAHA CHANNEL TO 20N170W TO 21N180W. THE PART OF THE TROUGH NEAR THE ISLANDS HAS BEEN MOVING TOWARD THE SOUTHEAST AT 10 MPH. ANOTHER TROUGH ALOFT IS CENTERED FROM 30N154W TO 26N160W.
