THE FIRST IS NORTH-NORTHWEST TO SOUTH-SOUTHWEST ORIENTED TROUGH ALOFT JUST TO THE EAST OF THE BIG ISLAND. THIS TROUGH HAS AN AXIS FROM 26N149W TO 21N154W TO 13N156W. A FEW THUNDERSTORMS ARE BEING GENERATED SURROUNDING THE SOUTHERN BASE OF THE TROUGH MOSTLY CONCENTRATED BETWEEN 10N TO 15N AND 148W TO 163W. A WEAK UPPER RIDGE IS PRESENT 400 MILES TO THE WEST OF KAUAI AND BOTH FEATURES ARE NEARLY STATIONARY. FURTHER TO THE WEST LIES ANOTHER UPPER LOW WITH A CENTER NEAR 23N178E. SCATTERED HIGH LEVEL CLOUDS ARE ASSOCIATED WITH THIS SYSTEM ACROSS THE NORTHERN FLANK OF THE LOW BOUNDED BETWEEN 25N TO 32N AND 172W TO 176E. AT THE SURFACE...A SLOW MOVING WEAK SURFACE TROUGH NEAR THE MAIN HAWAIIAN ISLANDS CONTINUES TO INDUCE BROKEN...OCCASIONALLY OVERCAST...LOW STRATUS CLOUDS AND SCATTERED LIGHT AND RADAR IS TRACKING MODERATE SHOWERS ACROSS THE MAIN HAWAIIAN ISLANDS AND ADJACENT WATERS. THE SURFACE TROUGH HAS A NORTH TO SOUTH AXIS FROM 19N159W TO 24N159W. CLOUDS AND SHOWERS MOTIONS OVER THE STATE ARE MOVING TOWARDS THE WEST-SOUTHWEST AT 10 TO 15 MPH. OVER THE MAIN HAWAIIAN ISLANDS...SCATTERED STRATOCUMULUS AND CUMULUS CLOUDS COVER MOST KAUAI. OAHU IS COVERED IN BROKEN TO OVERCAST CLOUDS. MOLOKAI HAS OVERCAST CLOUDS OVER THE WHOLE ISLAND. RADAR IS ALSO TRACKING SCATTERED SHOWERS PASSING ACROSS OAHU AND MOLOKAI WITH WINDWARD AND MAUKA AREAS RECEIVING THE BRUNT OF THE RAINFALL. LANAI HAS BROKEN TO OVERCAST CLOUDS OVER THE SOUTHERN HALF OF THE ISLAND WITH SMALL BREAKS OVER THE NORTHERN HALF. MAUI IS COVERED WITH OVERCAST CLOUDS INCLUDING HALEAKALA. A FEW BREAKS ARE OBSERVED ALONG THE NORTHWEST COAST.

A WEAK FRONT IS MORE THAN 280 MILES NORTH OF KAUAI IS SLOWLY MOVING TOWARD THE SOUTH AND SOUTHEAST. MOST OF THE CLOUDS ASSOCIATED WITH THE SYSTEM ARE CURRENTLY NORTH OF A LINE FROM 36N137W TO 28N152W TO 25N171W. THE LOW CLOUDS AT THE LEADING EDGE OF THE BOUNDARY ARE BECOMING MORE DIFFUSE WITH TIME. FAR SOUTH OF HAWAII IN THE ITCZ...A LARGE AREA OF MODERATE THUNDERSTORMS IS BOUNDED BETWEEN 04N TO 11N AND 170W TO 175E. SOME STORM TOPS ARE CLIMBING TO 50 THOUSAND FEET IN THIS AREA.
