ANOTHER BROAD UPPER LEVEL TROUGH IS SAGGING SOUTH ALONG 150W FROM 24N TO NORTH OF 30N. A SOUTHERLY UPPER LEVEL JET IS POSITIONED EAST OF THE FIRST TROUGH AND IS TRANSPORTING HIGH LEVEL MOISTURE NORTHWARD FROM THE TROPICS BETWEEN 161W AND 167W SOUTH OF 23N. ALL OF THESE UPPER LEVEL FEATURES ARE AFFECTING THE LOWER LEVEL CLOUD FEATURES AS A WEAK FRONTAL BOUNDARY IS DRAPED EAST TO WEST ACROSS THE REGION NORTH OF 24N. THE MOST ACTIVE CLOUDS AND SHOWERS ALONG THE FRONT ARE LOCATED ON THE FAR WEST END WHERE THE UPPER TROUGH IS INTERACTING WITH THE FRONTAL FEATURE TO CREATE SCATTERED THUNDERSTORMS WITH TOPS UP TO 40000 FEET WEST OF 173W BETWEEN 26N AND 21N. THE REST OF THE FRONTAL CLOUD BAND THAT STRETCHES FROM 26N173W TO 25N160W TO 24N150W TO 30N142W...IS ABOUT 200 MILES WIDE AND IS COMPOSED OF LOW TOPPED CUMULUS. CLOUD TOPS IN THIS BAND ARE AS HIGH AS 12000 TO 14000 FEET. THIS PORTION OF THE FRONTAL BOUNDARY...CURRENTLY LOCATED AROUND 170 MILES NORTH OF OAHU...IS MOVING SOUTH AT 5 TO 10 MPH. SCATTERED TO ISOLATED THUNDERSTORMS ARE FOUND ALONG THE SOUTHERN BORDER OF THE AREA SOUTH OF 13N ASSOCIATED WITH THE MAIN CONVERGENCE ZONE ALONG 09N-10N. HIGHEST CLOUD TOPS ARE 50000 FEET. ACROSS THE MAIN HAWAIIAN ISLANDS...BROKEN LOW CLOUDS ARE LOCATED OVER CENTRAL AND WESTERN TWO-THIRDS OF KAUAI...OVER THE WESTERN HALF OF OAHU...THE LEEWARD SIDE OF MOLOKAI...LANAI AND HALEAKALA ON MAUI.
