THE BIG ISLAND HAD BROKEN LOW CLOUDS OVER THE KONA SLOPES...THE WINDWARD SIDE OF THE KOHALA MOUNTAINS AND THE LOWER SLOPES OF THE HILO AND PUNA DISTRICTS. THE REST OF THE BIG ISLAND WAS PRACTICALLY FREE OF LOW CLOUDS. CLOUD TOPS WERE NEAR 6 THOUSAND FEET. CLOUD MOVEMENT WAS TOWARD THE WEST AT AROUND 20 MPH. HIGH CLOUDS MOVING RAPIDLY TO THE NORTH...IN COMBINATION WITH THE LOW CLOUDS...MADE FOR OCCASIONAL CLOUDY SKIES OVER THE MAUI COUNTY ISLANDS AND THE BIG ISLAND. THE HIGH CLOUDS WERE BETWEEN 20 AND 26 THOUSAND FEET...AND WERE BEING BLOWN OFF THE TOPS OF THUNDERSTORMS ALONG THE INTERTROPICAL CONVERGENCE ZONE...ITCZ...FAR SOUTHWEST OF HAWAII. AN INTERESTING FEATURE IN THE FORM OF A BROAD BAND OF LAYERED CLOUDS AND SCATTERED EMBEDDED THUNDERSTORMS WAS LOCATED FAR NORTHWEST OF KAUAI. THE CLOUDS WERE NORTHWEST OF A NORTHEAST TO SOUTHWEST ORIENTED COLD FRONT EXTENDING THROUGH 30N175W AND 26N180W. THE FRONT AND THE CLOUD BAND WERE MOVING TO THE EAST AT 10 MPH. ANOTHER INTERESTING FEATURE WAS A 250 MILE WIDE AREA OF BROKEN THUNDERSTORMS CENTERED AT 20N178W. THE THUNDERSTORMS WERE PROBABLY THE RESULT OF CONVERGENT LOW LEVEL SOUTHERLY FLOW SOUTHEAST OF THE COLD FRONT...AND DIVERGENT WESTERLY FLOW ALOFT. THE THUNDERSTORMS WERE STATIONARY WITH TOPS NEAR 45 THOUSAND FEET. ALOFT...ABOVE 25 THOUSAND FEET...A LOW WAS DETECTED BY WATER VAPOR IMAGERY ABOUT 200 MILES SOUTH OF KAUAI NEAR 19N160W. THE LOW WAS MOVING TO THE WEST AT 25 MPH. COUNTERCLOCKWISE FLOW AROUND THE LOW WAS RESPONSIBLE FOR CARRYING THE HIGH CLOUDS FROM THE ITCZ TO OVER THE EASTERNMOST ISLANDS. $$ CRAIG +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
