LOW CLOUDS ARE MOVING MORE QUICKLY OVER WINDWARD WATERS AS OPPOSED TO LEEWARD WATERS...DUE TO HIGH PRESSURE CENTERED FAR NORTHEAST OF THE ISLANDS...AND WEAK TROUGHING LOCATED WEST OF THE ISLANDS. LOW CLOUDS ARE PRIMARILY SCATTERED OVER WINDWARD WATERS EAST OF THE ISLANDS...BUT SCATTERED TO BROKEN CUMULUS /CU/ AND STRATOCUMULUS /SC/ ARE OVER WINDWARD WATERS EAST OF THE BIG ISLAND... AND OVER WATERS SOUTH AND WEST OF KAUAI. SKIES OVER KAUAI ARE GENERALLY PARTLY CLOUDY...ALTHOUGH BROKEN LOW CLOUDS ALONG THE SOUTH AND WEST SHORES ARE MAKING CONDITIONS CLOUDIER THAN NORMAL FOR THE LEEWARD COASTS...AND ADJACENT NEAR SHORE WATERS. ASIDE FROM A PATCH OF BROKEN CU ALONG THE NORTHEAST SLOPES OF MOUNT WAIALEALE...THE REMAINDER OF THE ISLAND IS UNDER FEW TO SCATTERED CU AND SC...DESPITE THE PRESENCE OF THIN CIRRUS MOVING OVER THE ISLAND FROM THE WEST. BROKEN LOW CLOUDS LINE THE SPINE OF THE KOOLAU RIDGE ON OAHU...WITH THESE CLOUDS EXTENDING OVER SOME WINDWARD COMMUNITIES ALONG THE EASTERN SHORE. THE REMAINDER OF THE ISLAND IS UNDER MOSTLY SUNNY SKIES...WITH THIN CIRRUS OVER WATERS NORTH OF THE ISLAND...AND SCATTERED SC OVER THE SOUTHWEST COAST AND ADJACENT NEAR SHORE WATERS. SKIES OVER MAUI COUNTY AND NEAR SHORE WATERS ARE MOSTLY SUNNY THIS MORNING...BUT PATCHES OF SCATTERED TO BROKEN SC AND CU ARE OVER WINDWARD SLOPES OF MOLOKAI... AND OVER THE EASTERN LOWER SLOPES OF HALEAKALA ON MAUI...NEAR KIPAHULU AND KAUPO. BROKEN TO OVERCAST SC AND ISOLATED EMBEDDED SHOWERY CU ARE OVER THE LOWER WINDWARD SLOPES OF THE BIG ISLAND... FROM LAUPAHOEHOE TO HILO TO VOLCANO TO PAHALA...AND EXTEND UP TO 50 MILES TO THE EAST. A DIFFUSE...150 MILE WIDE...BAND OF SHOWERY CU IS NORTHWEST- SOUTHEAST ORIENTED OVER WATERS EAST OF THE ISLANDS...WITH THE WESTERN PORTION OF THIS BAND 60 TO 80 MILES EAST OF THE WINDWARD SHORES. THE BAND IS LOCATED ALONG A LINE FROM 29N 159W TO 27N 159W TO 24N 157W TO 21N 154W TO 21N 148W...AND APPEARS TO BE MOVING ON A TRAJECTORY THAT WOULD KEEP THIS MOISTURE FROM MOVING INTO THE ISLANDS. LOW CLOUDS OVER WINDWARD WATERS EAST OF OAHU AND MOLOKAI ARE MOVING TOWARD THE NORTHWEST AT SPEEDS NEAR 30 MPH...WITH LOW CLOUDS SOUTH OF THE BIG ISLAND MOVING TOWARD THE WEST AT SPEEDS NEAR 22 MPH. LOW CLOUDS OVER WATERS SOUTH OF KAUAI ARE MOVING TOWARD THE NORTHWEST AT SPEEDS NEAR 18 MPH. NORTH OF 25N...THE NORTHERN PORTION OF THE BAND MENTIONED ABOVE IS MOVING TOWARD THE NORTH...AHEAD OF A COLD FRONT THAT IS WELL NORTHWEST OF THE ISLANDS...ROUGHLY ALONG A LINE FROM 30N 163W TO 27N 167W TO 26N 175W. THUNDERSTORMS HAVE INCREASED IN BOTH COVERAGE AND INTENSITY ALONG THE FRONT IN THE LAST COUPLE OF HOURS...WITH CLOUD TOPS REACHING AS HIGH AS 40 THOUSAND FEET. WATER VAPOR IMAGERY HIGHLIGHTS A WEAK TROUGH ALOFT ASSOCIATED WITH THE FRONT...WITH A WEAK TROUGH EXTENDING SOUTHWESTWARD ALONG A LINE FROM 28N 163W TO 23N 167W TO 19N 170W TO 13N 180. A WEAK AND RATHER SMALL RIDGE ALOFT LIES EAST OF THIS TROUGH...AND IS CURRENTLY OVER THE MAIN HAWAIIAN ISLANDS. $$ BIRCHARD +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
