THE RAGGED FRONT IS COMPRISED OF A 150 TO 175 MILE-WIDE BAND OF SCATTERED TO BROKEN CUMULUS AND STRATOCUMULUS CLOUDS STRETCHING ALONG 30N153W...27N164W...AND 29N177W. THE BROAD UPPER LEVEL TROUGH DRIVING THE FRONT LIES WELL NORTH OF 30N...LEAVING LITTLE UPPER LEVEL SUPPORT FOR THE FRONT WHICH IS DRIFTING TO THE SOUTH AT LESS THAN 10 MPH. THE FRONT HAS WEAKENED AND DISPLACED THE SUBTROPICAL RIDGE SOUTHWARD TO JUST OVER 200 MILES NORTH OF KAUAI. THE TRADE WIND FLOW AROUND THE MAIN HAWAIIAN ISLANDS IS DOMINATED BY FEW TO SCATTERED CUMULUS CLOUDS...THOUGH A SMALL CLUSTER OF BROKEN CUMULUS AND STRATOCUMULUS CLOUDS IS SKIRTING JUST NORTH OF THE BIG ISLAND. LOW CLOUDS ARE TRAVELLING FROM THE EAST NORTHEAST AROUND 15 NEAR THE SMALLER ISLANDS...INCREASING TO 20 MPH SOUTH OF THE BIG ISLAND. THE TRADE WIND FLOW IS PRODUCING SCATTERED TO BROKEN LOW CLOUDS OVER THE TYPICAL WINDWARD PORTIONS OF THE STATE. AFTERNOON SEA BREEZES HAVE LED TO THE DEVELOPMENT OF SMALL PATCHES OF BROKEN LOW CLOUDS ACROSS SHELTERED...LEEWARD SLOPES OF THE SMALLER ISLANDS. THIS EFFECT IS MORE PRONOUNCED ON THE BIG ISLAND...WHERE BROKEN TO OVERCAST LOW CLOUDS BLANKET THE KAU...SOUTH KONA...AND NORTH KONA DISTRICTS BELOW 8 KFT. THE PATTERN ALOFT OVER THE REGION IS COMPLEX BUT WEAK BETWEEN 30N AND 20N. AN UPPER LOW JUST WEST OF 180 GIVES WAY TO A WEAK UPPER RIDGE CENTERED ALONG 168W...FOLLOWED BY A WEAK UPPER LOW JUST NORTHEAST OF THE BIG ISLAND NEAR 20N156W THAT IS HAVING LITTLE EFFECT ON THE CLOUD FIELD AROUND THE ISLANDS. FARTHER EAST A STRONG UPPER RIDGE DOMINATES. THIS ENTIRE PATTERN IS SHIFTING WESTWARD SLOWLY. A SMALL AND WEAK TROPICAL DISTURBANCE NEAR 11N168W IS MOVING AWAY FROM THE MAIN HAWAIIAN ISLANDS TO THE WEST SOUTHWEST NEAR 20 MPH. THUNDERSTORMS WITH TOPS TO 46 KFT CONTINUE TO FLARE WITHIN THIS WEAK SYSTEM. $$ DWROE +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
