ANOTHER UPPER TROUGH WAS LOCATED FURTHER NORTHWEST OF THE AREA NEAR 30N180W...ALSO NEARLY STATIONARY. AN UPPER RIDGE DOMINATES THE AREA NORTH AND EAST OF 20N150W. THE UPPER TROUGH NEAR THE DATELINE IS PRODUCING THE MOST SIGNIFICANT WEATHER IN THE AREA WITH A BAND OF SCATTERED THUNDERSTORMS EMBEDDED IN A WIDE BAND OF LAYERED CLOUDS. THE BAND IS AFFECTING THE AREA WEST OF A LINE FROM 30N172W TO 15N180W. THE THUNDERSTORM TOPS IN THIS BAND ARE NEAR 50000 FEET. ANOTHER LARGE AREA OF MAINLY HIGH CLOUDINESS IS SURGING NORTHWARD AROUND THE UPPER TROUGH CENTERED JUST WEST OF THE MAIN HAWAIIAN ISLANDS. THIS BAND COVERS THE ENTIRE MAIN ISLAND CHAIN AND STRETCHES NORTH TO 27N AND SOUTH TO THE INTERTROPICAL CONVERGENCE ZONE...ITCZ...AROUND 10N...WHICH IS PROVIDING THE MOISTURE SOURCE FOR THIS UPPER LEVEL MOISTURE. ISOLATED TO SCATTERED THUNDERSTORMS COVERS TO AREA BETWEEN 10N AND 08N...ALONG THE ITCZ. DUE TO THE HIGH CLOUDS COVERING THE MAIN HAWAIIAN ISLANDS...LOWER LEVEL CLOUD FEATURES ARE NOT ABLE TO BE SEEN WITH SATELLITE IMAGERY. HOWEVER USING RADAR AND SURFACE OBSERVATIONS...BROKEN LOW CLOUDS WITH SCATTERED SHOWERS CAN BE FOUND OVER MOST OF KAUAI...OAHU AND THE WINDWARD WATERS OF OAHU AND MAUI COUNTY. SHOWERS ARE ALSO PERSISTENT ON WINDWARD MAUI AND MOLOKAI. LOWER CLOUDS AND SHOWERS ARE MOVING TO THE WEST AT AROUND 30 MPH IN AREAS FREE FROM THE ISLAND TERRAIN. $$ BRENCHLEY +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
